Research of Compress Storage Technique for C-TRDM

摘要

In this article, we introduce C-Temporal Relation Data Model(C-TRDM), and analyze data redundancy of tradition database and temporal database in existence. For the quantities of temporal database are increasing fleetly, we put forward compress storage tactics for temporal data which combine compress technology in existence in order to settle data redundancy in the course of temporal data storage and temporal data of slow acting domain and momentary acting domain are accessed by using each from independence clock method and mutual clock. We also bring forward strategy of gridding storage to resolve the problems of temporal datum rising rapidly.
