the database searching service since the 1960s is providing host-terminal computing. But, current developments in open systems computing, networking, client/server computing and standards for information management are changing today's systems. Bibliographic databases are most useful databases and they are provided by online database service, CD-ROM,OPAC and Internet. The World Wide Web will influence the design of database searching of the future as will users' damands for wider access. Because many users of these database are faced to difficult to access in the complexed circumstance, database agent is needs to access different network information resources. But this database agent device has some problems. Requirements for database agents are to identify automatically interfaces (commands) and databases of individual systems. These problems will be found the solution by the analysis of existing searching systems. Another problem is the automatic relevance judgment. It is necessary to recognize the concept of relevance judgment and divide the element of the relevance between users judgment and system judgment.Client/server architecture based on Z39.50 standards achieves compatibility for retrieval between diverse database searching systems. Z39.50 standards will influence some library OPAC,but this standard is not considered the multi-literal database searching

自1960年代以来的数据库搜索服务提供了主机末端计算。但是，开放系统计算，网络，客户端/服务器计算和信息管理标准的当前发展正在改变当今的系统。书目数据库是最有用的数据库，它们由在线数据库服务，CD-ROM，OPAC和Internet提供。全球网络将影响未来数据库搜索的设计，用户的少量少量访问更广泛。由于这些数据库的许多用户在复杂的情况下很难访问，因此需要数据库代理来访问不同的网络信息资源。但是该数据库代理设备有一些问题。数据库代理的要求是识别自动接口（命令）和单个系统数据库。这些问题将通过分析现有搜索系统找到解决方案。另一个问题是自动相关性判断。有必要认识到相关性判断的概念，并将用户判断与系统判断之间的相关性元素划分。基于Z39.50标准的知名度/服务器架构实现了各种数据库搜索系统之间检索的兼容性。 Z39.50标准会影响某些库OPAC，但该标准不被视为多文字数据库搜索
