Embodiment Construction

[0028] Further details will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0029] First, DBES processes the message flow, such as figure 1 shown.

[0030] The "application layer client-database engine system DBES-database server" architecture realizes the database access process according to the following steps:

[0031] 1. The database engine system DBES is started, and the specific background database server driver is loaded according to the definition of the configuration file to complete the database connection;

[0032] 2. After the database engine system DBES confirms that the database connection is successful, it establishes a connection with the system message bus, registers the unified data interface on the system message bus in service mode, and prepares to provide follow-up services;

[0033] 3. The client application program selects the application data access interface according to the specific application type, encapsu...

Abstract

The invention provides a heterogeneous database access method. According to the JDBC technology, the ODBC technology, the ADO technology and the BDE technology, the problems existing in the data access cross-platform characteristic, the data access cross-development-language characteristic and the data access cross-development-environment characteristic are solved, data access efficiency is fully considered, access modes of different data types and large-capacity data types are achieved through a specific method, developers of an application layer abandon the complex SQL, database storage process development work focuses on achievement of application service logic, and the database developers can focus on the characteristics of different database servers, organize service data formats and improve data access efficiency. For the developers, a mature system structure model and professional development work division are adopted, and application system development reliability can be improved.

Description

technical field [0001] The invention relates to a data processing method, in particular to a database access method. Background technique [0002] With the current development of computer technology, the ability to access databases is becoming more and more important. When implementing certain system applications, developers must consider the deployment of different types of relational databases to adapt to the existing IT management structure of the enterprise. Different enterprises have different choices for database systems. If an application system mandates the type of database server, it may be necessary to increase the enterprise's investment in database servers and increase maintenance investment in database services. And if a system application can be deployed according to the existing database server of the enterprise, it can save the enterprise's investment in the database, help protect the original investment, and simplify the solution and cost of system deploymen...
