Embodiment Construction

[0037] The technical content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The embodiment of the present invention provides a scientific and technological resource integration system based on a multi-source database. For the metadata or related information of multi-source heterogeneous scientific and technological resources, the integrated system cleans the data source according to the original storage method and stores it in the multi-source database. Users can query the data through a unified data query engine. The ultimate goal is to uniformly store and manage scientific and technological resource information using metadata in a specified format or standard form. The following is a detailed description of this.

[0039] Such as figure 1 As shown, the science and technology resource integration system is mainly composed of acquisition layer, processing layer, presentation ...
