Description
Technical field
The invention belongs to technical field of computer information processing, more particularly to a kind of novel dynamic generation data operation commands
Analyzing platform and design method.
Background technology
With the development of computer information technology, used software systems scale is also increasing.In office system, pipe
Reason type system and information issuing system, e-commerce system etc. fields are directed to Database Systems, what software systems were related to
Data are stored in the database mostly.
During above type of software system development, need to deposit the corresponding data of each tables of data exploitation
It takes, parsing function.In practical applications, due to the difference of input data source and presentation mode, often there is a tables of data pair
Answer one or more data models.When updating the data the corresponding tables of data in library, specific aim is needed to write increase, modification, deletion
The Sql command codes of data.In the process, to the data type of each member, data length (size), each word in data model
Effect (major key certainly increase type column, unique key) of the section in tables of data is handled.It is relatively more in software systems larger data table
When, corresponding Sql command codes are also by proportional increase.More in business module, when tables of data quantity is big, workload is non-
Chang great can occupy a large amount of project development period.
In the project of team unity, due to the technical strength of developer and the difference of coding style, software can be caused
Quality control difficulty is big in systems development process, and normalization, robustness, the maintainability of program also will be with the increasings of system scale
Add and constantly improve difficulty, stability and data processing preciseness, the correctness of software systems are difficult to control, and are occupied very
The development time of large scale, increase the testing cost and maintenance time of software, software project development is very high with maintenance cost.

A kind of design method of novel dynamic generation data operation commands, includes the following steps,
(1) after analyzing platform receives model analyzing request, judge whether data model has tables of data identity property, such as
Fruit does not have tables of data identity property then to terminate to parse work, returns and terminates parsing reason and exit analyzing platform；Have, carries out next
Step；
(2) data table name and the owner in the Data Identification attribute of parsing data model；
(3) data model member property traversal is carried out, parsing is skipped when member property is without field identification attribute, continues to examine
Look into next member property；When member property has field identification attribute, next step is carried out；
(4) various data types, format and the constraints such as sub- attribute field name, the data type in field identification attribute are checked
Description information；
(5) it uses the constraint information obtained in step (4) to verify data model member attribute value, works as verification result
When meeting the constraint rule that member property defines, continue the parsing of next member property, otherwise terminates to parse work, return terminates
Parsing reason simultaneously exits analyzing platform；After all member properties of data model check, and in all member properties at least
There are one member properties to have field identification attribute, carries out next step；
(6) it is identified according to data model tables of data and is generated with member property value with the member property respectively with field identification
Sql orders return to the Sql orders of generation and exit data model analyzing platform, otherwise terminate to parse work, return and terminate parsing
Reason simultaneously exits analyzing platform.
Preferably, when establishing data model, " tables of data " attribute is identified in model class, and table name and the owner are set
Information；" field identification " attribute is set in data model on member property corresponding with tables of data, is arranged according to actual conditions
The sub- attribute field of " field identification " attribute；Sub- range of attributes be used to reflect the characteristic of corresponding data sheet field with about
Beam；" tables of data " attribute is parsed and is handled for data model analyzing platform with " field identification " attribute.
Own preferably, analyzing platform identifies the corresponding database table of generation model according to " tables of data " of data model
Person and title, according in " field identification " of data model member field name, whether generate corresponding Sql from adding attribute
More newer field, by the attribute field data type of data model, attribute value generation updated value, and most according to " field identification "
Long length with whether allow to carry out normative constraint for sky；Whether it is to add certainly, is whether unique in being identified according to " field identification "
Key, whether major key determines the constraints of the Sql command codes of generation.
Compared with prior art, advantageous effect possessed by the present invention is：Development approach through the invention establishes data
Model, the data model analyzing platform by the present invention carry out entity data model parsing and generate Sql orders, without being grasped to data
Make layer individually to be encoded, or need to only encode on a small quantity, size of code can be significantly reduced especially for large software system, improves
Development efficiency；Sql sentences needed for database update using the method are dynamic generation, so simultaneously specification to greatest extent
Sql command code formats effectively reduce problem difficult in maintenance caused by due to writing style difference, improve the close friend of code
Property and terseness；Simultaneously because Sql orders result from data model analyzing platform, also have in terms of safeguarding with extension very big excellent
Gesture.
