A Wide-area Data Resource Management Method Based on Data Dictionary

Abstract

The invention relates to a data dictionary based wide area data resource management method. The data dictionary based wide area data resource management method includes preprocessing existing data resources under the condition that existing data and applications are undamaged and unaffected, generating an independent dictionary entity with data resource characteristics, designing a data dictionary management mechanism, indexing data by a multi-level data dictionary way, compressing the data dictionary by the similar clustering technology and optimizing the data retrieval process; deploying the data dictionary in a wide area network system, supplying data index services, locating the data resources by a network host through the data dictionary and accessing the data entity. By the data dictionary based wide area data resource management method, unified maintenance and efficient sharing of the data resource among nodes of the wide area network are realized and instantaneity and uniformity of data access of clients are ensured by the aid of the unified and universal data dictionary. The data resources within the whole network can be interconnected and shared, utilization rate of the data resources is increased and management efficiency of the data resources is improved.

Description

technical field [0001] The invention relates to a resource management method in the technical field of power grid dispatching automation, in particular to a data dictionary-based wide-area data resource management method. Background technique [0002] The existing smart grid dispatching technical support system has good horizontal integration and vertical penetration capabilities, which can fully meet the needs of various disciplines of the current dispatching organization. In the future, the power grid will be tightly coupled, and the dispatching system will be globally wide-area and dynamically integrated. In the existing system, data resources are scattered in each dispatching area, adopting a centralized management method, and providing data access services in the area through the primary / standby server. In this way, some problems are brought about: 1. The visibility of data resources is limited to a single scheduling area, and data resources cannot be managed uniformly...

Problems solved by technology

In this way, some problems are brought about: 1. The visibility of data resources is limited to a single scheduling area, and data resources cannot be managed uniformly and shared across the entire network; 2. The management efficiency of data resources within the entire network is low, enabling cross- Zone data access needs to be reprocessed after receiving the original data from the data source; 3. The same data may be stored on nodes in multiple different scheduling zones, resulting in multiple data sources and low utilization of data resources
