摘要
数据库技术的发展经历了格式化数据库、关系数据库、面向对象数据库及XML数据库等几个阶段.数据库系统结构由集中走向分布,利用CGI、ASP、PHP、ODBC、JDBC、JSP等技术可实现网上数据库的动态访问.数据库技术经历了半个世纪的发展过程,各数据库系统呈现出极强的异构性,互操作问题是数据库技术研究的热点;跨库检索、数据仓库、Z39.50、OAI、Webservices等是当前互操作的主要技术.
The development of database has experienced several phases, such as format database, relational database, object-oriented database and XML database, from concentrated to distributed structure, dynamic visit can be realized by the technologies of CGI, ASP, PHP, ODBC, JSP, etc.. Over a half century, quite different structures of database system have formed, co-operation has been the focus of attention in the research, on-line retrieval, data bank, Z39.50, OAI, Web services are the main techniques.
