Design and Implementation of Storage Manager in Main Memory Database System ALT I BASE™

摘要

Conventional database systems are optimized for the particular characteristics of disk storage environment. Main memory database systems use the different implementation techniques to structure and organize the user data and system catalogs. In this paper, we present the design and implementation considerations of our main memory database system ALTIBASE™ that is currently applied to the time-critical applicaitons. We focus on the design issues of storage manager in ALTIBASE™. The major components are introduced, and features and characteristics of transaction management method are described. In order to evaluate our transaction performance, we show various experimental reports as measured by the TPS.
