Embodiment

[0039] The user's call record in the data warehouse of the telecom industry is one of the main data, which has a large amount of data and has great business significance. This embodiment takes the call record as an example to illustrate the specific implementation method of the present invention:

[0040] 1. Basic layer:

[0041] Call records are generally kept for about half a year. Through analysis, the fields in it, such as: calling and called, long-distance roaming, own party's attribution, counterparty's attribution, settlement party and other fields are all enumerated fields. Using the data compression technology of the data warehouse can greatly save data storage. Specific steps are as follows:

[0042] 1) Compression value selection:

[0043] When the field type is CHAR, the average length of bytes occupied by the field value is relatively uniform, and the value range does not exceed 255, you can compress all the value ranges as compressed values ​​to achieve an ef...

Abstract

The invention relates to a method of saving memory and constructing a green data warehouse, comprising procedures as follows: (1) Saving memory of a base layer using method of data compression; (2) Saving memory of a collection layer using method of granularity memory such as user class-fine-grained class-coarse-grained class; establishing automatic, configurable and regular data cleaning mechanism for business data which exceeds memory cycle; (3) Adjusting memory cycle according to life cycle of application analysis for application layer; establishing automatic, configurable and regular data cleaning mechanism for business data which exceeds memory cycle. The invention has the advantage of effectively saving memory, automatically cleaning data garbage in time, and enabling clean and neat green data warehouse.

Description

technical field [0001] The invention relates to a method for saving storage and building a "green" data warehouse, which is suitable for the telecommunications industry. Background technique [0002] A data warehouse is a subject-oriented, integrated, time-varying, non-volatile collection of data that supports management decision making. The data warehouse built by telecom operators generally includes data in multiple subject areas such as customers, accounts, bills, customer service, and network management. Through the ETL process, the production data is extracted from BOSS, CALLCENTER and network management system to the data warehouse system, and then loaded into the data warehouse after conversion. Then, through the automatic scheduling mechanism, the data is layered, divided into granularities, and summarized, and the data is formed into a data mart or an application summary layer, and then according to different applications, the application layer data of each star st...
