Abstract

The invention provides a data retrieval method and system, and belongs to the field of databases, wherein the system comprises external databases and a search engine thereof, internal databases and a search engine thereof, a literature comparison module, a data presentation module and a registration and login module. A user logins the registration and login module; the registration and login module automatically logs in all external databases and internal databases; keywords are input in the registration and login module and search is determined, that is, the search engines of all the external databases and internal databases are automatically started, and the keywords are used for searching; and the literature comparison module extracts the literatures searched from all the external databases and internal databases, compares the literatures searched from the databases, and sends a final search result to the data presentation module for presentation according to a preset priority adoption sequence in a manner that only one literature is adopted for the same literature. According to the retrieval method and system, literature retrieval is carried out in the internal databases and the external databases through the keywords at the same time, and the workload of respective retrieval in different databases is reduced.

Description

technical field [0001] The present invention relates to the field of databases, in particular, to a data retrieval method and system. Background technique [0002] In order to comprehensively search for literature, people often need to search different database systems, such as CNKI, the US FDA Orange Book, China CDE API registration platform, etc. It will be very time-consuming and laborious if you log in to each database and enter keywords to search. [0003] CN 112487014A discloses a SQL data processing method, device and background server. The background server is connected to the client in communication, and the background server logs in to multiple databases at the same time. The SQL data processing method includes: acquiring a plurality of pieces of SQL data submitted by the client; wherein, each piece of the SQL data is given an identifier of the database pointed to; the database; respectively send each piece of the SQL data to the corresponding database to obtain ...
