摘要
针对传统数据库和现有时态数据库中存在数据冗余及时态数据库中数据量快速增长等现象,结合现有的压缩技术,提出了时态数据压缩存储策略来解决时态数据存储中的数据冗余现象,并用分立时钟法和共用时钟法对缓变域、瞬变域时态数据进行存储。提出网格存储策略来解决时态数据快速增长问题。
Because there is datum redundancy in tradition database and temporal database in existence and the quantities of temporal database are increasing speedly. We put forward compress storage strategies for temporal datum which combine compress technology in existence in order to settle datum redundancy in the course of temporal datum storage and temporal datum of slow acting domain and momentary acting domain are accessed by using each from independence clock method and mutual clock method we also bring forward...
