| 摘要: |
| 实时数据库(real-time database,简称RTDB)要求以内存数据库(main memory database，简称MMDB)作为其底层支持.内存数据库的脆弱性使得数据库的装入(包括初装和重装)极为频繁,对系统性能影响极大,而传统的装入算法对实时内存数据库不适用.为此给出影响数据装入的实时数据及事务特征,并提出一种数据装入策略与算法. |

| Abstract: |
| A real-time database (RTDB) requires a main memory database (MMDB) to support it as its base. The vulnerability of an MMDB makes its loading (including initial loading and reloading) very frequent, which has a large influence on system performance. Traditional database loading approaches are not suitable for Real-Time MMDBs. In this paper, the authors first give the properties of real-time transactions and data which have influence on the loading of a database, then present a strategy and algorithm for DB loading. |
| Key words: Real-Time database, main memory database, database loading, data access priority. |
