Abstract

The invention discloses a database dynamic management method based on XML (extensible markup language) metadata. The method comprises the following steps: 1, organizing an XML storage structure and defining XML node information including user-defined business rules; 2, building a metadata analysis engine; 3, building a business dispatch execution engine; 4, building an interface for calling data by an external program; 5, and importing and exporting business data. The whole database structure is described from the perspective of businesses, all metadata in a database and the whole structure are stored in an XML, and by the analysis engine and the execution engine which are combined with the structure, the database can be directly operated by the substituted engines; the design process of the system database is simplified, the flexibility and the expansibility of the database design are simultaneously enhanced, the integration with the outer system is better, and great convenience is provided for data exchange, particularly complicated business data exchange.

Description

technical field

[0001] The invention relates to a database dynamic management method, in particular to a database dynamic management method based on XML metadata. Background technique

[0002] With the development of database and software, the storage of data in the database is no longer a problem, but as the business development in each software system becomes more and more complex, the relationship between data business tables is intricate, how to have a great impact on the system database structure Good description and management have become another important issue of data storage in the software development process.

[0003] For the data of general small-scale business systems, the business is relatively simple, the amount of data is small, and the demand for data exchange is weak, so it is not difficult for database management. In the face of large-scale systems, the current management methods are mostly based on ordinary documents or simple charts. These methods canno...
