| 摘 要： | 目前国内外图书馆信息管理系统的检索系统一般都是基于CöS 的体系结构, 并且有的还采用了COM 技术, 使系统能保护图书馆已有的软硬件资源, 并且其可维护性也有了很大提高。在此基础上, 我们采用当前在许多企业应用系统中流行的分布式技术—DCOM 技术来开发了一个图书馆分布式检索系统, 简称LDRS, 该系统在可扩展性、稳定性、负载平衡性、容错性等方面都比原有的检索系统得到了增强, 能更好的满足未来大量的读者访问需求。

| Abstract: | At present the existed library information retrieval systems are commonly based on C/S system, and some have adopted COM technology, to protect the software and hardware resources in library, and increase maintainability . Based on the theory above, we apply the DCOM technology, which is widely used in many enterprises application systems, to develop the library distributed retrieval system (LDRS). The system has strengthened noticeably in expansibility, stability, load balance, fault tolerance and will meet the requirement of large number access in the future. |
