Embodiment 1

[0027] Embodiment 1: Establish a dynamic virtual data warehouse in multiple transactional database collections:

[0028] (1) Define metadata: collect business requirement data from multiple transactional database collections, and divide the collected data into technical metadata and commercial metadata for definition. The specific way to define the above data is as follows:

[0029] ①. Define technical metadata: define objects and data structure information in multiple transactional databases, descriptions of data conversion, mapping from source data to target data, possible calculation methods, user access rights, and information release history as technical metadata. And provide these data defined as technical metadata to the designers and managers of dynamic virtual data warehouses for development and daily management;

[0030] ②. Define business metadata: define the data described from the perspective of enterprise business in multiple transactional databases, that is, d...

Embodiment 2

[0040] Embodiment 2: Establish a dynamic virtual data warehouse in a single small database:

[0041] (1) Define metadata: collect business requirement data from a single transactional database collection, and divide the collected data into two types: technical metadata and business metadata for definition. The specific way to define the above data is as follows:

[0042] ①. Define technical metadata: define objects and data structure information in a single transactional database, description of data conversion, mapping from source data to destination data, possible calculation methods, user access rights, and information release history as technical metadata data. And provide these data defined as technical metadata to the designers and managers of dynamic virtual data warehouses for development and daily management;

[0043] ②. Define business metadata: define the data described from the perspective of enterprise business in a single transactional database, that is, define...

Abstract

The invention relates to a method for establishing a dynamic virtual data base in an analyzing and processing system, which comprises the following steps: (1) defining metadata; (2) constructing a dimension indexing table; (3) constructing data marts; (4) instantiating the data marts; (5) constructing and instantiating a plurality of the data marts; and (6) dynamically modeling and instantiating the virtual data base. The method collects service required data from an enterprise database, defines fields with analysis significance into the metadata, carries out dynamic modeling, dynamic extraction and conversion processing on the corresponding metadata, constructs a plurality of the data marts conforming to an analysis subject and instantiates the virtual data base so as to realize the zero storage of the data in the virtual data base, overcome contradictions between system equipment resources and continuously increased information quantities and meet the requirements of high efficiency and data real-time for a management decision database of a decider.

Description

technical field [0001] The invention relates to a method for establishing a dynamic virtual data warehouse in an analysis and processing system. Background technique [0002] Today, with the rapid development of the global economy, whether it is a multinational company, enterprise or government agency, a large amount of data needs to be processed every day. These data are often scattered in transactional databases under various application systems, such as production, sales, finance, etc. data. Decision makers often need to find the data they need from these large amounts of data for analysis in order to make correct and timely decisions. But in the face of such a large amount of data, relying on the traditional data warehouse implementation method cannot achieve the functions of dynamic modeling of data, real-time dynamic extraction of data and real-time online analysis of information. [0003] As we all know, through the use of ERP (the abbreviation of the English full n...
