Research And Implementation Of International Business Settlement System With Memory-based Database

The traditional database management system for all of the data is placed in the disk management, the frequent need to access a disk for data operation. As the disk data access itself performance bottleneck, the database management system performance was very limited. However, in recent years, with the rapid development of computer technology, in order to solve this problem has a realistic possibility:the memory capacity of the rising and falling prices; the computer to enter64age, the operating system can support a larger address space. It is based on technology development, as well as the market for more rapid and real-time database management system demand, the memory database (MDB) system.This article from the actual needs of projects, to main memory database methodology principles as a guide, combined with Hongkong Unicom International Settlement System (IDD settlement) status, in the analysis of Hongkong Unicom International Settlement System Problems under the premise to try local transformation and the use of memory database. Papers from the user needs to start, a detailed analysis of Hongkong Unicom International settlement system problems, and related business functional requirements, introduces main memory database for settlement.
