The integration of data resources refers to the integration method of removing duplicate information from data objects in related databases, which not only provides users with a unified query interface, but also provides non-duplicate and high-quality information. Combination mode is the organic optimization and integration of multiple database systems, which is not only the integration of information in different digital resource systems, but also the optimization of digital information quality. ?
Integration mode of data resources integration;
It is mainly an integration method based on OPAC resource system. OPAC is an important digital resource system in the library, and the integration of OPAC resource system is the most basic way to integrate digital resources in the library. It is mainly realized by implementing Z39. 50 protocol, aggregate heterogeneous OPAC databases on different platforms, and establish a bibliographic integrated retrieval system.
Users can retrieve the OPAC of related libraries through the OPAC system interface. For example, the "Multi-node Database Retrieval" of the "Webpac Retrieval System" of Shanghai Jiaotong University Library can search Shanghai Jiaotong University Library, East China Normal University Library and Fudan University Library by author, title, subject, keywords and standard book number on a unified retrieval interface.
The OPAC bibliographic information of Shanghai Library does not need to switch back and forth between different OPAC interfaces of each library. South Korea's "National Library Integrated Information System" can retrieve books, periodicals, CDs, videos, audio and other materials at one time. Fusion and integration are actually the integration and merging of digital information in different OPAC systems.
