The information collection system collects text information, images, monthly data of economic operation, annual data, etc. on the Internet through search engines, and enters the collected information into corresponding databases by category through the information entry module shown in Figure 2. Then, through the information review module, information management module and information statistics module shown in Figure 2, the entered information is reviewed, re-edited, and deleted, and the number of reviewed information is counted according to the column, time, and entry personnel. The data processed above are stored in structured database and unstructured database respectively through the information exchange interface, and the corresponding structured data and unstructured data are described in metadata, and then the information is stored in the database shown in Figure 1 The information database on the server, and the multimedia files are stored in the file server shown in Figure 1.

Then, the backup server shown in FIG. 1 performs a backup operation on the above-mentioned information database; the personnel with corresponding authority realize background management through the application server shown in FIG. 1 .

As shown in Figure 2, the above-mentioned unstructured database includes a picture database, a video database, and an audio database; the above-mentioned structured database includes: a model database, an index database, a basic database, and an expert database.

The above-mentioned model library is used to collect practical models and analysis methods in macroeconomics, and to organize and teach these models and analysis methods and continuously enrich them into the model library. Make some mature models suitable for user applications into semi-automatic and interactive processes for users to use.

The purpose of the above-mentioned index database is to establish an index system library that needs to be used in quantitative analysis in macroeconomic decision-making analysis, and to establish a time-series database that can be used for economic calculation and analysis. The index system is embodied in a tree structure, which can Click to expand and select; considering the relatively large index library, there should be an index search function; each index can display monthly value, monthly growth rate, cumulative value, and cumulative growth rate according to different economic significance; you can query the required data by time period. The query results are required to be exported in EXECL format, displayed in charts, simple statistical analysis and correlation analysis. Among them, the indicators provided in the indicator library are divided into monthly indicators, annual indicators and annual CD-ROM data.

The base library mentioned above is used to create indicators. The specific indicators are determined by the user, and the data source is implemented by the user.

The above-mentioned expert database aims to provide diversified decision-making support functions to meet the multi-level needs of analysts and decision-makers. The data exported by the system or external data can be analyzed or modeled with the E-VIEWS software provided by the system. The analytical methods provided by the system can also be used for quantitative analysis to obtain the information required for decision-making.

A single conventional database technology is far from being able to meet the integration, interaction, information extraction and fusion of massive and multi-source heterogeneous data. Therefore, the above-mentioned economic operation analysis system adopts multi-source, heterogeneous and object-oriented data warehouse technology, including data mining and data fusion, to overcome the defects of single database technology. As shown in the flow chart of data fusion in Figure 3, this economic operation analysis system divides unstructured databases into heterogeneous databases on the Internet and various heterogeneous databases existing in intranets of various institutions according to the nature and location of unstructured databases. processed using different techniques. For Internet heterogeneous databases, use Internet mining technology, Internet search technology, and network radar to search for useful information from Internet web pages or professional websites. For the various heterogeneous databases existing in the intranet of each organization, the heterogeneous and heterogeneous data from multiple data sources are integrated by establishing a data warehouse, and processed and sorted into a usable data resource to meet the needs of decision support. demand.

Users use full-text search and knowledge search tools to meet their needs for searching structured and unstructured information. Data mining and OLAP (OnLine Analysis Process, Online Analytical Processing) are operations performed on the data warehouse, and they are all analysis tools based on the data warehouse. Data mining is a mining analysis tool, which mainly uses various analysis methods to actively mine the laws contained in a large amount of data, while OLAP is a proof-seeking analysis tool, that is, there is a hypothesis, through OLAP to get verified. The two analysis tools, data mining and OLAP, are complementary and can be used together. OLAP can help people put forward hypotheses, and can also verify the results predicted by data mining; data mining can dig out a conclusion, but whether this conclusion is correct or not can be verified by OLAP.

The above-mentioned heterogeneous database is a collection of multiple related database systems, and its purpose is to realize the merging and sharing of data information resources, hardware equipment resources and human resources among different databases. Each of the above-mentioned database systems already existed before joining the heterogeneous database system, and had its own DMBS. Each component of the heterogeneous database has its own autonomy. While realizing data sharing, each database system still maintains its own application characteristics, integrity control and security control. The heterogeneity of heterogeneous database systems is mainly reflected in the following aspects:

■Heterogeneity of computer architecture: each participating database can run on mainframe, minicomputer, workstation, PC or embedded system respectively.

■ Heterogeneity of the basic operating system: the basic operating system of each database system can be Unix, Windows NT, Linux, etc.

■Heterogeneity of DMBS itself: It can be Oracle, SQLServer, etc., which are both relational database systems, or databases with different data models, such as relational, schema, hierarchical, network, object-oriented, and functional databases together form a heterogeneous Database systems.

With the help of data warehouse technology, information can be collected from multiple databases in the heterogeneous database system, and a unified global model can be established. At the same time, the collected data also supports access to historical data. Query for decision support.

On the basis of establishing the information base, the WEB application server will publish information through the information release subsystem; end users log in through the browser involved in the client subsystem, and retrieve information according to their needs. The retrieved information is dynamically displayed to the customer after being processed.
