ssdb 中文意思是什麼

ssdb 解釋
文獻數據庫
  1. 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 )

    本文的主要研究結果如下:提出了適合科學與統計數據庫的兩種數據壓縮存儲策略，其分別為ccss （ column - compressedstoragesystem ）和rcss （ row - compressedstoragesystem ） 。
  2. 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，本文的研究內容包括:研究適合於科學與統計數據庫的數據壓縮演算法及存儲結構;研究在壓縮科學與統計數據庫上的查詢處理技術，包括數據操作演算法和查詢優化演算法。
  3. 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

    科學與統計數據庫（ scientificandstatisticaldatabase ， ssdb ）具有如下特點: （ 1 ）關系的模式穩定、屬性值的值域有限、數據冗餘大; （ 2 ）新產生的數據只追加到當前數據末尾而不更新已有內容; （ 3 ）每個關系都由大量屬性組成，但大多數查詢只與少數幾個屬性相關且多為只讀操作。
  4. Above characters are in favor of integrating compressed database technology with ssdb

    上述特徵都適合於將壓縮數據庫技術集成到ssdb中去。
