Catalog generating method based on refined data items

Abstract

The invention discloses a catalog generating method based on refined data items. A data item catalog is established according to a data source, wherein the catalog is a logical catalog or a physical catalog, the catalog is composed of data items or fields, and the data source comprises a database of a shared interface and / or collected data; local or all data of the database can be accessed throughthe shared interface of the database, wherein the collected data source comprises data acquired from a webpage or a network interface containing data or a server or a computer host through a networktool, the catalog data comes from an original table or a newly-built data table which generates a mapping relation with the database of the shared interface, and the newly-built data table data comesfrom an original table which generates a mapping relation with the database of the shared interface or a data table established according to the collected data. According to the method, the catalog based on the refined data items can be provided, the cross-platform or cross-system data items can be freely combined, and catalog generation is flexible and comprehensive.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a catalog generation method based on refined data items.

Problems solved by technology

The existing catalog generation methods cannot directly generate data item catalogs, but can only generate a catalog in batches or as a whole, and the catalog can only reach the level of information resources, and the degree of subdivision is not enough

At the same time, the existing catalog generation methods cannot integrate information from multiple data sources (that is, cross-platform or cross-system) to generate a catalog based on data items.
