Problems solved by technology

Similar policy data stored in different formats in various regions needs to be modeled so that policy data can be shared, transformed, and used in a consistent manner across the enterprise, and during development, changes to the database structure directly affect the entire The life cycle and operation of the software system, if there is no good management method, the software system will not be able to operate, it will be difficult to expand, it will not be able to be re-developed, and it will soon lose its use value
[0003] The current common practice is to draw the data model through the Power Designer software, but the difference between different data model files cannot be controlled, and the difference between the data model file and the database cannot be controlled
Inability to effectively manage the data model
It can be seen that the existing data model processing methods have the following disadvantages: 1), the difference between different data models cannot be controlled
2), unable to control the difference between the data model file and the database
3), unable to centrally manage the data model

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] figure 1 It is a schematic diagram of the difference control flow of the data model of the present invention.

[0017] See figure 1 , the difference control method of the data model provided by the present invention comprises the following steps:

[0018] Step S1: Obtain the PDM model (Physical Data Model) files of different versions of the database; PDM is to store database table data in XML format, the structure is very complicated, and it is necessary to understand the structure content (the meaning of each label definition); read the PDM Documentation, explaining the content is one of the difficulties. The present invention uses JAVA to read the XML format, interprets the tags defined in the XML, and processes information such as library table association relations, field types, field lengths, primary key relations, foreign key relations, ...

Abstract

The invention discloses a difference control method of a data model. The method comprises the following steps that (a), PDM (physical data model) files of different version databases are obtained; (b) the data structure of each basic element in the PDM files is extracted and is stored into a database; (c) the data structures of all of the basic elements in the two PDM files are read from the database for one-by-one difference comparison; (d) difference results of the two version databases corresponding to the two PDM files are displayed by adopting visualization patterns and statistical data. The difference control method has the advantages that the data structure of each basic element in the PDM files of different version databases is extracted, and the difference results of the two version database are displayed through one-by-one comparison, pattern visualization and data statistics, so the data models can be collected in a unified way, various data models can be fast and conveniently managed, in addition, the differences of different version data models can be accurately distinguished, and the effective difference control is realized.

Description

technical field [0001] The invention relates to a data model processing method, in particular to a data model difference control method. Background technique [0002] Global data is growing rapidly, but IT budgets are not keeping pace. This harsh reality means that information leaders must manage data smarter, focusing on operational efficiency anytime, anywhere. At the same time, there is a large amount of data, and these data are growing exponentially year by year. The more useful the data model is to the enterprise. Similar policy data stored in different formats in various regions needs to be modeled so that policy data can be shared, transformed, and used in a consistent manner across the enterprise, and during development, changes to the database structure directly affect the entire If there is no good management method for the life cycle and operation of the software system, the software system will not be able to operate, it will be difficult to expand, it will no...
