Abstract

The invention provides a cross data source inquiry device which comprises a main data source selection module 102, a first inquiry module 104, a data acquisition module and a second inquiry module. The main data source selection module is used for selecting one database from a plurality of databases to serve as a main data source. The first inquiry module is used for conducting data inquiry in the plurality of databases except the main data source to obtain inquiry result data. The data acquisition module is used for acquiring the inquiry result data of the databases except the main data source into the main data source. The second inquiry module is used for conducting data inquiry in the main data source to obtain final inquiry result data. Correspondingly, a cross data source inquiry method is further disclosed. By means of the technical scheme, enterprises can have a light-weight technical scheme with low construction cost, short construction period, large inquiry data quantity, various data logic structure and high generality when conducting cross data source inquiry, so that the device and the method ensure that the enterprises can effectively resolve the problems of large data quantity and too large pressure of an application server.

Description

technical field [0001] The invention relates to the field of data query, in particular to a cross-data source query device and a cross-data source query method. Background technique [0002] With the deepening of enterprise information application, the internal information system of the enterprise has gradually developed from the early departmental single business system to the coexistence of multiple business systems. At the same time, the report data required by the management is often comprehensive data, and it is often difficult for us to obtain all relevant data from a single business system. At this time, we need to query data from different business systems, and then combine these data from different sources After processing, organize in the same report. From a technical point of view, each business system corresponds to a data source, and the query of multiple business systems is a cross-data source query. [0003] For cross-data source query issues, the following ...
