Embodiment Construction

[0018] The implementation of the method for uniformly accessing the database system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 It is a schematic diagram of the unified database interface structure of the short message system. Due to space limitations, this figure only draws the structure of the two databases encapsulated by Oracle's OCI and SYBASE's DB LIB as a schematic illustration. For the convenience of description, the following two are used The encapsulation of one type of database is described as an example. As for the application of more other types of databases, those of ordinary skill in the art can also achieve the purpose and effect of the present invention on the basis of understanding the present invention.

[0020] Such as figure 1 As shown, generally, the application program should actively initiate a connection to the database server, and maintain the validity of the connection u...

Abstract

The method of efficient and united access of data base system includes following steps: creating data base connecting pond; classifying ground level calling interfaces of data base systems according to their functions; packing the ground level calling interfaces based on the classification; making dynamic base with the packed united data base interfaces; and read or write access via the data base. Practical test shows that the present invention has 20-30 % higher efficiency compared with the system adopting ODBC technology, raised data base access rate and greatly raised processing capacity. Owing to the packed ground level interfaces of several kinds of data base systems, the present invention may be used in commercial data base systems through simple configuration.

Description

technical field [0001] The invention relates to the field of databases, in particular to a method for accessing various types of databases by using a unified database interface. Background technique [0002] With the continuous advancement of database technology, in order to improve work efficiency and service level in all walks of life, the application of database is becoming more and more extensive. Such as communication, financial security, water supply, power supply, weather service and other fields, after the introduction of the national unified service number, the dependence on the database system is increasing. [0003] However, because the database systems in various places are not launched at the same time, the specifications and formats are different; even in different regions of the same system, there are many tricks, and the access methods to the database are also different. This state greatly affects the normal coordinated operation of the entire database syste...
