- Above characters are in favor of integrating compressed database technology with ssdb
上述特征都适合于将压缩数据库技术集成到ssdb中去。 - The main results are as follows : ( 1 ) two kinds of compression and storage strategies for ssdb are provided , and they are ccss ( column - compressed storage system ) and rcss ( row - compressed storage system )
本文的主要研究结果如下:提出了适合科学与统计数据库的两种数据压缩存储策略,其分别为ccss ( column - compressedstoragesystem )和rcss ( row - compressedstoragesystem ) 。 - So this paper focuses on the researching about data compression methods and storage architectures which are suitable for ssdb and corresponding query processing technology on them , including data operations and query optimizations
因此,本文的研究内容包括:研究适合于科学与统计数据库的数据压缩算法及存储结构;研究在压缩科学与统计数据库上的查询处理技术,包括数据操作算法和查询优化算法。 - Scientific and statistical databases ( ssdb ) have following characters , firstly , relation schema is relatively stable , and each attribute has limited candidate values with high redundancy , secondly , new arrival data only append to the end of current data area and do not change the exist data , thirdly , every relation is made up of plenty of attributes , but majority of queries only relative with less attributes and most queries are read - only queries
科学与统计数据库( scientificandstatisticaldatabase , ssdb )具有如下特点: ( 1 )关系的模式稳定、属性值的值域有限、数据冗余大; ( 2 )新产生的数据只追加到当前数据末尾而不更新已有内容; ( 3 )每个关系都由大量属性组成,但大多数查询只与少数几个属性相关且多为只读操作。
