| 摘要: |
| 本文提出了一种支持实时事务的预分析算法和基于该算法的主存数据库内外存替换策略．它首先预分析实时事务以获得事务存取行为的知识，再在事务执行时，进行基于这些信息的存取及内外存数据交换，从而实现主存数据库管理和支持实时事务的定时限制. |

| Abstract: |
| In this paper, the authors present transaction pre analysis and data I/O strategies of a main memory database to support real time transactions. A real time transaction is firsly pre analyzed to get the information about access behavior of the transaction, the system performs data I/O between main memory and secondary storage (if necessary) based on the information. Therefore, the main memory database requirements are implemented and thus real time transactions are supported. |
| Key words: Transaction pre analysis real time transaction real time database main memory database |
