Description

System and method for automatic business generation based on graphical business scenarios and domain templates

technical field

The present invention relates to a system and method for automatically generating business based on graphical business scenarios and domain templates. Specifically, it relates to a system where users use computer software to build graphical business scenarios. An automatic service generation system for dynamically customizing domain templates and a method for generating application software or services meeting the requirements of the scene belong to the technical field of the Internet and telecommunication networks.

Background technique

In the software development process, requirements analysis is the most basic and most important operation step. A common phenomenon is that the solutions designed and developed by the developer cannot always meet the requirements of the demander, resulting in a waste of funds and resources. This is the problem caused by inaccurate or incomplete demand acquisition. Therefore, the process from requirement analysis to software formation is the focus of people's research.

Requirement Engineering (Requirement Engineering) refers to the application of proven effective techniques and methods for requirements analysis to determine customer needs and help analysts understand the problem, and define all external characteristics of the target system. It systematically describes the system to be developed, its behavioral characteristics and related constraints through appropriate tools and notations, forms a requirements document, and supports the evolution of users' ever-changing requirements.

Requirements engineering runs through the entire process of software development, assisting developers to complete requirements acquisition, software development, and software management. However, at present, requirements engineering is more used in the field of requirements acquisition, and its role in the development and maintenance process has not been well reflected.

At present, some research results are only to obtain requirements, and most of the process of obtaining requirements is manual operation according to certain set steps, resulting in low efficiency, especially the obtained requirements cannot be directly used for the automatic generation of software/services . Although some research results can be used to generate software/services, usually the process does not include a requirements analysis phase; that is, users are required to complete the requirements analysis themselves. This puts forward higher requirements for users: users need to have certain relevant field knowledge and be able to conduct comprehensive demand analysis. Moreover, this method artificially divides requirements analysis and software generation into two stages, which is not conducive to software management and does not make full use of the capabilities provided by requirements engineering. Therefore, how to make demand analysis and software/service generation a coherent process, which is convenient for users to use and easy for software management, is a problem worthy of research by technical personnel in the industry.

At present, requirements engineering and software/service automatic generation technology have become scientific research hotspots. The following introduces two related patent applications that have been published.

(1) Scenario-based requirement analysis technology: "A System for Establishing a Software Requirement Model and a Method for Establishing a Software Requirement Model" (application number: 201110323553.7), which discloses a method of establishing a software requirement model to analyze demanded system. The system includes a software requirement information processor, as well as input devices and output interfaces. The software requirement information processor includes: a software requirement information unit, a scenario building unit, a behavior model building unit, and a software requirement model detection, modification and output unit. The steps of establishing the software requirement model are: A. Input the software requirement information; B. Establish the scene; C. Establish the behavior model; D. Detect, modify and output the software requirement model.

It should be noted that this method uses natural language to input requirements, and uses natural language to describe the requirements and scenarios in the viewpoint. Therefore, the degree of analysis and detection and modification is based on the analysis of natural language. Instead of conducting a comprehensive and thorough analysis of requirements through other more visual, direct, and friendly methods, such as graphics, it is easy to lose some hidden needs of users.

At present, the existing scenario-based requirements analysis technology still needs to describe the requirements first (usually using natural language). However, in the process of converting subjective requirements into natural language descriptions by users, some requirements (such as some non-functional requirements or potential requirements) may have been lost. Therefore, the scene analysis based on natural language description itself has incomplete and inaccurate requirements description, which will directly lead to the redefinition and supplement of requirements in the software development process, thus increasing the additional workload.

In addition, the current scenario-based requirements analysis technology is limited to obtaining the requirements model, and cannot directly use the requirements model to generate software. However, for software users, the most important concern is not whether the demand model is comprehensive and perfect, but whether the final software or service meets their expectations. Therefore, how to better apply the results obtained from requirements analysis to the software generation process is a more worthy question.

(2) Automatic software/service generation technology: "A Method for Generating Software Services According to User Needs in a Network Environment" (application number: 200110011940.6), which discloses a method for generating software services according to user needs, the steps are as follows: Users submit service requirements through the client; the server analyzes user requirements, extracts user-required functions and related software component fields, obtains all component information and sends it to the client; interface; the client sends the connection plan to the server; the server generates a software service assembly according to the user connection plan, and finally sends the generated service program to the client.

The feature of this patent application is: the premise of generating software services is that the user selects the components and connects the component interfaces by himself. Most of the operations in this way are completed by the users themselves; the server only provides an operation to generate services from the connection scheme. There are too many operations on the client side, which complicates the generation process. If the server can directly generate a similar template frame according to the user's graphical scene, and present it to the user, instead of the user choosing components, it will save a lot of energy for the user. In addition, the component analysis process in this patent application is a text matching process, which will also bring a relatively tedious workload.

To sum up, the existing software/service automatic generation technology has the following defects:

First, in the requirement acquisition stage, existing software generation technical solutions require users to input software requirement information, which is usually a requirement document described in natural language, or a requirement model described in a modeling language, and then the system analyzes these requirements, Map it to the corresponding domain. This kind of software/service generation technology is only for users who have sufficient professional knowledge and can accurately conduct demand analysis and modeling. In addition, this solution cannot assist users in requirement analysis and mining, nor can it detect and avoid errors made by users in the requirement analysis stage, which will bury hidden dangers for the generation and maintenance of software/services.

Second, in the software/service generation stage, the existing technology is based on the selection and assembly of software/service components: the system first analyzes user needs, provides a list of optional components, and then the user selects the components to be used for assembly. This process also puts forward higher requirements for users. Whether the optimal component is selected, whether the connection and configuration of the components are correct, all determine the quality of the generated software/service. Moreover, the system is only responsible for verifying the correctness of the software/service process, without considering the improvement and optimization of its performance, which also makes the quality of the software/service not guaranteed.

third. In terms of architecture selection, the system is based on the client/server (C/S) architecture, and the user must first install the client to use the system to generate software. Compared with the C/S architecture, the browser/server (B/S) architecture adopted by the present invention has obvious advantages: firstly, it is easy to operate, and the user does not need to have a strong professional background. Therefore, the user level adapted to by the present invention is more wide. Secondly, it is easy to maintain and has strong scalability. It only needs to update and maintain the server to complete the upgrade and maintenance of system functions. Finally, strong compatibility avoids problems caused by different development tools and version differences.

Therefore, how to further improve and innovate existing technologies has become the focus of attention of scientific and technological personnel in the industry.

(51) The domain template customization module transforms the business process mapping into a directed graph with a starting point and an ending point according to the process structure and semantic information in the business process description file;

(52) Plan a minimum path set so that it can cover all paths in the directed graph, that is, include all conditional branches in the business process;

(53) Select a path in the collection, and then test the path in the selected domain template; if the domain template meets the conditions of this path, then jump to step (55); otherwise, execute step (54 );

(54) extend or modify the domain template so that it satisfies the conditions of this path, and remove the path from the collection;

(55) Determine whether the path set is empty, if so, execute step (56); otherwise, return to execute step (53), that is, select the next path;

(56) Complete the customization or expansion of the domain template, and then use the path optimization algorithm to merge and split the path branches, and save the optimized domain template.

In the step (7), the operation of component selection module to search and select qualified components includes the following contents:

(71) The component selection module reads the first component information in the domain template;

(72) Search for components that meet the requirements of the domain template in the component library, and match their interface, semantics, and functional information. If there is one or more matching components, jump to step (74); otherwise, there is no If there is a matching component, execute step (73);

(73) Search the network for components that meet the matching requirements through the search interface. If the search is successful, perform step (74). If the search is unsuccessful, prompt the user that no suitable component can be found, and end the process;

(74) Select a component from the set of candidate components, test whether its interface, semantics and functions are correct, if correct, record the test data into the candidate list, otherwise, delete the component from the candidate list; then judge Whether all candidate components have been tested, if so, execute step (75); otherwise, return to execute this step (74);

(75) According to the test data, select the optimal component from the candidate component list, and add it to the component list of the template and the adaptation file;

(76) Determine whether all the components in the domain template have been matched, if so, execute step (77); otherwise, read the next component information, and return to execute step (72);

(77) Complete the search and matching of components, and store the operation results in the component list and adaptation file of the domain template.

The candidate component list is a list of all components in the domain template that meet the set requirements; the component list is set for each template, and is used to describe all the components that need to be filled in the template.

The innovative features of the system and method for automatically generating software based on graphical business scenarios and domain templates of the present invention are: after the user builds a graphical business scenario in the system of the present invention, the system automatically acquires and analyzes user needs, and dynamically customizes them according to user needs The domain template finally generates software or services that meet the requirements of the scenario. Therefore have the beneficial effect of following improvement and innovation:

In the requirements acquisition stage, the existing requirements analysis technology requires users to input software requirements information using a requirements document described in natural language or a requirements model described in a modeling language, and then the system analyzes these requirements and maps them to the corresponding domain. The present invention obtains the needs of users by means of graphical scene construction, which not only can accurately analyze the needs of users, but also does not require certain professional knowledge like natural language, and easily loses potential needs of users. Because the graphical way to build the scene is vivid, direct and friendly; more importantly, the graphical method can conduct a comprehensive and thorough analysis of requirements, assist users in demand analysis and mining, and can also detect and prevent users from generating problems during the demand analysis stage. mistake.

In the software/service generation stage, the existing technology is based on the selection and assembly of software/service components: the system first analyzes user needs, gives a list of optional components, and then the user selects the components to be used for assembly. In the present invention, the system directly customizes or expands a similar template frame according to the user's graphical scene, and automatically searches out some components and presents them to the user for selection; instead of directly selecting the components by the user. This will save a lot of energy for the user, and also reduce the requirements for user qualifications. More importantly, the system is not only responsible for verifying the correctness of software/services and processes, but also provides users with optimal components and modification suggestions, and can also ensure the quality of software/services.

In terms of architecture selection, the existing technology is based on the C/S architecture, and the user must first install the client if he wants to use the system to generate software. The B/S (browser/server) architecture adopted by the present invention has significant advantages: first, it is easy to operate, and users do not need to have a strong professional background, so the present invention is applicable to a wider range of users. Secondly, it is easy to maintain and has strong scalability. It only needs to update and maintain the server to complete the upgrade and maintenance of system functions. Furthermore, the compatibility is strong, avoiding the problems caused by different development tools and version differences.

Therefore, the present invention has very good application prospects.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The system and method for automatically generating business based on graphical business scenarios and domain templates in the present invention provide users with a graphical interface, users can build business application scenarios according to their own needs, and the system automatically analyzes the scenarios built by users, and obtains Analyze and analyze user needs, and finally generate software or services that users need. Referring to Fig. 1 below, the working principle of the system of the present invention is briefly described.

The first step is to create a graph mapping library, a domain template library, and a component library, which provide support for mapping from graph scenarios to software. When a user needs to customize a software or service, the user first drags and drops the graphic label in the graphical interface on the browser to build the application scenario of the software/service. The system first parses the scene into a business process description file and a user requirement description file through a graph mapping library. Then use the parsing result to find the domain template that meets the user's requirements in the domain template library, and complete the dynamic customization or extension of the domain template. Since the customized or extended domain template only provides the process structure of the software, it is necessary to add components to the customized or expanded domain template including the software or service process structure and its business description information through searching and testing. Components that meet the requirements found in the library, that is, component modules that can complete the set functions, so as to realize the functions of software or services, thereby completing the software/service generation process. Finally, test and deploy the generated software or service so that users can access or use the customized software or service.

Referring to Fig. 2, introduce the structural composition of system of the present invention: this system is made up of the three-layer framework of browser, server and database, the function of these three-layer components is explained respectively below:

The first layer is the browser: the interface component for the system to directly interact with the user. The human-computer interaction interface presented by the browser has the following four functional units: graphic scene construction unit, domain template customization unit, component selection unit and Business operation/management unit;

The graphic scene building unit, as a key component in the interactive interface, is used to provide users with dragging and dropping the graphic labels on the toolbar to build a graphic business scene. There are three types of graphic tags: role class, entity class and action class. The role class includes people or external characters who interact with the system; the entity class is a physical device (such as a phone) that can complete the set function, or describe software or services An abstract functional entity (such as software services); action classes are various operations performed by roles, and the role of action classes is to connect roles and entities, or entities and entities.

The domain template customization unit is responsible for receiving the domain template customized or extended by the server after the user saves and uploads the completed graphical business scene to the server, and presenting the domain template and process structure information to the user for confirmation It needs to be modified; and when the user modifies the domain template, an editing interface for modifying the template is provided; the template confirmed by the user is used to generate software or services.

The component selection unit is responsible for obtaining the list of components to be used returned by the server when using a customized or extended template to generate software or services, and presenting it to the user for the user to confirm whether modification is required; or when manually reselecting components to generate software or services When , a user selection interface is provided to generate a new component list.

The business operation/management unit is responsible for providing users with an interface for testing and deployment after the selected templates and components are assembled into the software or services users need. Users can also access and manage their customized software or services through the business operation/management unit; if they need to modify the software or services, they can return to the above-mentioned corresponding interfaces presented by the browser interface, and each unit can re-customize them.

The second layer is the server: the control core and operation center part of the system, which is responsible for the overall planning and regulation of itself and other two parts, so as to automatically generate application software or services; it is equipped with a graphic element mapping module, a domain template customization module, and a component Selection Module and Software/Service Generation Module The following four components:

The graphic element mapping module is used to complete the mapping of graphic business scenarios built by users to the process and semantics of software or services, because each graphic tag represents a set role, entity or action, and each graphic tag is mapped to a Extensible Markup Language XML (eXtensible Markup Language) description file, and in this file corresponds to a record containing description information, connection information and configuration information. All graphical labels can be mapped to corresponding records in the database. This module can complete the following three functions:

1) Extract demand semantics: extract the entire graphic business scenario and/or the semantic description of each graphic label, and when extracting semantics, in addition to extracting the semantics represented by the graphic label itself, it is also necessary to analyze the user’s configuration information to obtain its implicit Included needs.

2) Extract business process: First, analyze the main process of the software or service according to the connection relationship in the graphic business scene; then obtain the branch process in the software or service process according to the function definition of each graphic label.

3) Create a demand model: According to the type, function and semantics of each graphic label in the graphic business scenario, as well as the interaction relationship between them, the user-customized software or service demand model is obtained.

The domain template customization module is used to search for domain templates that meet the requirements in the domain template library according to the software or service process and requirement description obtained by the graphic element mapping module, and complete the customization or expansion of the domain template to transform it into one that meets user needs The software or service template, the functions completed by this module are as follows:

1) Search and match: According to the semantic description of software or service functions and their processes, search for qualified domain templates in the domain template library; if there is no matching domain template in the template library, search for matching domains on the network through the interface template.

2) Expansion and customization: When the domain templates found in the domain template library or the Internet cannot fully meet the requirements of software or service processes, they are responsible for expanding and customizing the domain templates, and adding the expanded and customized optimized domain templates to In the domain template library, in order to realize the scalability of the domain template library and improve the reusability of the domain template.

3) Process optimization: If the expanded domain template has covered all the needs of users in terms of software or service processes, but there may be some redundant or overly complicated branches, responsible for merging or splitting these process branches to improve software or services structural defects, optimize the entire software or service process and reduce the complexity of its generation and maintenance.

The component selection module, because the expanded domain template obtained from the domain template customization module is just a business process framework, to form the software or service required by the user, it is necessary to add functional components to the template, which is the function of the component selection module : Responsible for sequentially scanning the expanded domain template obtained from the domain template customization module, that is, the business process framework, and sequentially selecting or adding required functional components to form the software or service required by the user. The selection of each component is divided into two stages: firstly search for the components that meet the requirements in the component library, if the search result is an empty set, search for components on the network through the search interface; then include functions, Test the interface and performance, and record the results; after completing the testing of all components, compare the test results, and select the optimal component as a candidate component.

The software/service generation module is responsible for integrating software or services after selecting all the components in the template. The software or service generation process is divided into three parts: assembly, testing, and deployment:

Assembly is to integrate components and templates, complete interface adaptation, and shape software or services;

Testing is to test the correctness of the assembled software or service according to the user's needs and business processes;

Deployment is to deploy the generated software or service in the network environment after passing the test for users to use.

The third layer is the database: as the resource pool of the system, it is used to provide support for various resources during the entire process of generating software/services by the system; it is equipped with:

The graph mapping library is used to store the semantics, logic, operation and other information corresponding to each graph tag, so that when the graph mapping library is queried, the graph tag is converted into a set of description information, and the mapping support from the graph scene to the software or service is realized .

The domain template library is used to store multiple domain templates containing descriptive information, so that when searching for keywords, semantics or attributes in the domain template library, domain templates that meet the set requirements can be obtained. The domain template library supports customization, expansion and optimization for users to create and store their own domain templates.

The component library is used to store different functional components and their descriptions (that is, the execution file and component description information of the functional component), so that when searching for components, the description information can be found; or when testing components, use component execution files for testing; the component The library supports extensions and optimizations.

The user software configuration library is used to record various related information about the configuration and operation of user-customized software, and provide support for the operation and maintenance of software or services.

Referring to Fig. 3, the following operation steps of the method for automatically generating business by the business automatic generation system based on graphical business scenarios and domain templates of the present invention are introduced:

Step 1. The user drags and drops the graphic tags in the browser interface to build graphic business scenarios and configure interactive information: the system uses the graphic scene building unit of the browser interface to query the graphic mapping library to know the graphic business scenarios built by users by dragging and dropping graphic tags. Interaction information with the configuration, and after the graphical scene is built, the business scene is converted into a business description file.

In step 2, the graphical element mapping module of the server analyzes and extracts the user's demand information according to the business description file of the business scenario to form a business process description file and a user demand description file.

Step 3: The domain template customization module of the server analyzes the semantic description in the business process description file and the user requirement description file, and performs semantic matching and searching in the domain template library. If a matching template is found, jump to step 5; otherwise, That is, if no matching template is found, perform the subsequent step 4.

Step 4, the domain template customization module searches the corresponding domain template from the network through the search interface, and if the match is successful, proceed to the next step 5; otherwise, prompt the user that the matching template cannot be found, exit the program or re-edit the business scenario.

Step 5: The domain template customization module of the server dynamically customizes, expands and optimizes the searched domain templates according to the business process description file and user demand information. This step includes the following operations (see the flowchart shown in Figure 4):

(51) The domain template customization module transforms the business process mapping into a directed graph with a starting point and an ending point according to the process structure and semantic information in the business process description file;

(52) Plan a minimum path set so that it can cover all paths in the directed graph, that is, include all conditional branches in the business process;

(53) Select a path in the collection, and then test the path in the selected domain template; if the domain template meets the conditions of this path, then jump to step (55); otherwise, execute step (54 );

(54) extend or modify the domain template so that it satisfies the conditions of this path, and remove the path from the collection;

(55) Determine whether the path set is empty, if so, execute step (56); otherwise, return to execute step (53), that is, select the next path;

(56) Complete the customization or expansion of the domain template, and then use the path optimization algorithm to merge and split the path branches, and save the optimized domain template.

Step 6: The server returns the customized, expanded and optimized domain template and its description information to the user through the domain template customization unit of the browser. If the user needs to modify the template, the domain template customization unit completes the editing or After modification, re-upload and store; if the template does not need to be modified, proceed to step 7.

Step 7: According to the principle that each software or business corresponds to a template, and each template corresponds to multiple components, the component selection module completes the customized domain template and its description file according to the newly added domain template library, and searches the component library for matching conditions , and save the selected component information in the component list.

In this step, the operation of component selection module to search and select qualified components includes the following contents (see Figure 5):

(71) The component selection module reads the first component information in the domain template;

(72) Search for components that meet the requirements of the domain template in the component library, and match their interface, semantics, and functional information. If there is one or more matching components, jump to step (74); otherwise, there is no If there is a matching component, execute step (73);

(73) Search the network for components that meet the matching requirements through the search interface. If the search is successful, perform step (74). If the search is unsuccessful, prompt the user that no suitable component can be found, and end the process;

(74) Select a component from the candidate component set to test whether its interface, semantics and functions are correct, and if it is correct, record the test data into the candidate list (the candidate component list is all components in the domain template that meet the set requirements component list), otherwise, delete the component from the candidate list; then judge whether all candidate components have been tested, and if so, execute step (75); otherwise, return to execute this step (74);

(75) According to the test data, select the optimal component from the candidate component list, and add it to the component list of the template and the adaptation file;

(76) Determine whether all the components in the domain template have been matched, if so, execute step (77); otherwise, read the next component information, and return to execute step (72);

(77) Complete the search and matching of components, store the operation results in the component list of the domain template (the component list is set for each template, and is used to describe all the components that need to be filled in the template) and the adaptation file.

Step 8: The server returns the list of components to be used to the user through the component selection unit in the browser. If the user still needs to manually select components, it returns and presents a list of optional components for the user to choose; and the component selection module selects The selected component is tested, and after passing the test, it is saved in the component list and adaptation file; otherwise, perform the next step 9;

Step 9: The software/service generation module assembles software or services according to the business template, component list and adaptation files, completes testing and deployment, and ends the entire operation process.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
