Data integral service system and method

Abstract

The present invention relates to a data integrated service system. Said system includes a data register module, it is used for registering and storing data range provided by said data source and a data inquiry module, it is connected with said described data register module and one or several data sources and is used for giving inquiry request to correspondent data source and outputting the inquiry result to user. Besides, said invention also provides a data integrated service method and its concrete service steps.

Description

technical field [0001] The present invention relates to a data integration service system and method, in particular to a system that can support different data sources, shield the differences of different data sources through a unified data access method, support flexible query conditions, and make full use of the powerful retrieval function of the database. And a data integration service system and method that provide a powerful data filtering function to meet complex application development needs. Background technique [0002] Due to historical or other reasons, many enterprises already have a variety of business systems, resulting in increasingly serious information islands within enterprises. According to a report by IDC in 2001, among the world's largest 1,000 enterprises, there are an average of 14 databases and 48 An application system, and with changes in the market and customer needs, companies are constantly increasing its applications. For the consideration of re...

Problems solved by technology

[0009] 2. The client application development of data integration services changes due to different data sources;

[0010] 3. The same data access cannot span different types of data sources;

[0011] 4. Limited by the functions supported by the database, some special data filtering cannot be completed

[0014] 1. The ability of data filtering is limited and cannot meet the needs of complex applications;

[0015] 2. The rules of data conversion and integration are integrated in the custom code, making it difficult to flexibly adapt to changes

[0018] 1. The database optimizer and powerful retrieval functions cannot be used, and the performance is not high;

[0019] 2. The update of data by other database clients cannot be notified to the data integration service in time;

[0020] 3. Solve data integration by forming an intermediate library or a centralized library. However, this approach often forms a new data island
