Problems solved by technology

[0004] Database conversion is a complex issue. It is necessary to consider the differences between heterogeneous databases, such as the incompatibility of different database elements, data type issues, and database platform system environment configuration issues. There is no mature one-click conversion method yet

Embodiment Construction

[0032] 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.

[0033] The present invention aims at that various relational databases are created according to the data model, so at first the data model of the source database is converted into a basic data model (i.e. database data model) by reverse engineering, and then this basic data model Through forward engineering conversion to the data type required by the target database, it solves the rapid data conversion of heterogeneous databases.

[0034] An embodiment of the present invention provides a database converter, such as figure 1 shown, including:

[0035] Model storage module 101, is used for storing the mathematical model corresponding to each database; Each kind of database corresponds to a kind of mathematical model;

[0036] Conversion parameter obtaining module ...

Abstract

The invention provides a database converter and a conversion method. The database converter and the conversion method can adapt to arbitrary conversion between multiple heterogeneous databases, and free conversion between various databases is realized by aid of a language file in a certain format through automatic matching between a pre-stored data model and a data model. Therefore, sufficient application and sharing of data in different management information system databases are realized, user experience is improved, and the database converter and the conversion method have broad application prospects.

Description

technical field [0001] The invention relates to the field of computers, in particular to a database converter and a conversion method. Background technique [0002] In today's information society, people's daily work and life are inseparable from data and information. The processing of these information data, such as collection, storage, screening, query use and maintenance, is a very tedious work that we consciously or unconsciously carry out every day, which requires the establishment of a database. In the late 1960s, a new data management system, computer database technology, appeared. With the database system, we can statistically retrieve and search a large number of materials, and perform classified printing. Database technology is needed in teaching management, household registration management, personnel management, library management, salary management, warehouse management, finance, taxation, etc. [0003] In the development, management and maintenance of the dat...
