Data searching method and device for heterogeneous data sources

Abstract

The invention provides a data searching method and a data searching device for heterogeneous data sources. The method comprises the steps of capturing webpage source codes of each data source, extracting basic information of objects included by each data source webpage from the webpage source codes, and storing the information as an original data file; reading the original data file, extracting object association information, and updating an object database; establishing or updating an index of each piece of object association information in the object database according to a preconfigured index structure; and querying the index of the object database according to a received user access request, acquiring the corresponding object association information, assembling into a page and returning the page to the user. According to the method and device provided by the invention, automatic information collection, analysis, searching and exhibition are performed on the heterogeneous data sources, the operation cost is low, and the operation is simple and convenient.

Description

technical field [0001] The present application relates to the technical field of data search, in particular to a data search method and device for heterogeneous data sources. Background technique [0002] With the development of information technology, in the face of massive web content, people need to browse the information through data search. The independent data sources that already exist are usually called heterogeneous data sources. Each component of a heterogeneous data source has its own autonomy, and each source still maintains its own application characteristics, integrity control, and security control. Users log in to various heterogeneous data sources (websites), and perform data searches and browse webpage content according to their different data structures. However, in this mode, on the one hand, it is limited to different business scenarios. Information needs to go through a long manual or semi-automatic process from publishing, reviewing, and engine indexin...

Problems solved by technology

However, in this mode, on the one hand, it is limited to different business scenarios. Information needs to go through a long manual or semi-automatic process from publishing, reviewing, and engine indexing from online to providing to users for browsing, which requires certain operating costs; On the other hand, the information provided by different data sources (websites) has different data structures, and users cannot fulfill diversified information browsing needs through data search.
