Embodiment Construction

[0048] The present invention aims at the present situation that in the current telecommunication management network (TMN) system, the difference between data caused by time cannot be compared and analyzed directly, intuitively and flexibly, and proposes a method of using incremental storage to store data. And further compare and analyze the differences between the data.

[0049] Before introducing the concrete technical scheme of the present invention, some explanations are made to the premise and environment of the present invention's realization, referring to Fig. 1:

[0050]1. The invention purpose of the present invention is to solve and improve the problem and current situation of the telecommunication management network on the difference processing between data, but the present invention is not limited to be used in the telecommunication management network system, that is, the present invention is not limited by the specific data management system . For the convenience ...

Abstract

The disclosed method applicable to data changed along with time includes following steps: (1) data management system determines that type of each piece of data in data source is new added data, deleted data or modified data; (2) increment storing is carried out for the said different types of data so as to generate relevant records, as well as timestamp and symbol of type are setup in each record; (3) based on timestamp in each record in step (2), analysis and comparison are carried out for the said new added data, deleted data or modified data at any two pointed moments. The invention analyzes and compares discrepancy between data caused by time change, and solves large quantity of data to be backed up effectively.

Description

technical field [0001] The invention relates to the field of data storage and management, in particular to a method for analyzing and comparing differences of data that changes over time. Background technique [0002] The fields involving data storage and management are very extensive. Take the telecom management network system with relatively large data volume as an example. [0003] In the Telecom Management Network (TMN) system, in order to ensure the normal, stable and safe operation of the system, it is necessary to manage the data of several functional modules such as configuration, performance, fault, statistics and security. [0004] In order to ensure the normal operation of the system, or for the purpose of optimizing the system, the system administrator needs to check the latest current data of the system, as well as the data at a certain point in history. In many cases, system administrators will have a need to compare current data with historical data at a cert...
