Method for construction of distributing storage data file sharing system based on gridding

Abstract

'Based on mesh distributing stored data file sharing system construction method', a solving method for realizing data sharing among 'virtual enterprise' formed by a plurality of enterprises. By utilizing data-base technology and mesh platform among 'virtual enterprise', the method builds a data sharing system which can ensure not only data sharing but also a single data source. Each enterprise of the system respectively builds its own sharing data-base which is loaded, maintained and managed by data administrator of the enterprise. The data file is stored in each enterprise's sharing data-base in distributed type. The method realizes data sharing by building a uniform data directory, and realizes synchronizing renewing of data directory by using functions of the mesh platform. The sharing data file in data-base is encoded by an unite bite to build up a data directory and a data dictionary, and is transferred with enterprise code to ensure a single data source. The method realizes synchronizing update utilizing a synchronizing mechanism of the mesh platform.

Description

Technical field: [0001] The invention relates to a data file system construction method for realizing multi-enterprise data file sharing and ensuring distributed storage of a single data source. The system is based on grid platform and distributed database platform environment. Background technique: [0002] In order to make full use of resources, the "virtual enterprise" jointly established by multiple enterprises is currently widely implementing off-site design and manufacturing. For example, the development of the helicopter of AVIC Second Group Company is basically designed by Jingdezhen Helicopter Design Institute, Harbin Harbin Air Group is responsible for manufacturing the rotor system of the aircraft, and Jingdezhen Changfei Group Company is responsible for the final assembly. The helicopter engine is designed by Zhuzhou Engine Research Institute, Harbin Hahang is responsible for the manufacture of the engine transmission system, and Zhuzhou Southern Power Company i...

AI Technical Summary

Problems solved by technology

[0007] ●The PDM systems adopted by each enterprise are different, and it is difficult to realize unified data exchange;

[0008] ●"Virtual enterprise" is a consortium, it is difficult to establish a unified shared database, and shared data requires distributed storage;

[0009] ●Each enterprise participates in international cooperation, and the drawing files of various product models are coded according to the coding rules of foreign companies, resulting in different coding systems, which makes it difficult to ensure the unity of data and realize the management of a single data source
