跨平台的一致化数据库管理系统今后大规模信息系统的发展方向,是包括大型主机、中小型机、RISC工作站和个人机,并充分利用不同平台各自优势的所谓复合客户机/服务器体系结构(Compound Client/Server Architecture)。在大型主机和AS/400平台上,DB2是主要的关系型数据库平台,此外,在UNIX和OS/2服务器平台以及DOS、WINDOWS和OS/2客户机平台的Client/Server环境中,DB2的应用也愈来愈广泛,技术优势也愈来愈明显。下面分别按超级服务器、服务器和客户机三个层次上,将DB2产品家族在不同平台上的数据库产品概述一番:
Cross-platform consistent database management system The future direction of large-scale information systems development, including the mainframe, small and medium-sized machines, RISC workstations and personal machines, and make full use of the advantages of different platforms so-called composite client / server architecture Client / Server Architecture). DB2 is the main relational database platform on mainframes and AS / 400 platforms. In addition, on UNIX and OS / 2 server platforms and Client / Server environments for DOS, WINDOWS, and OS / 2 client platforms, DB2 applications Also more and more extensive, the technical superiority is more and more obvious. The following were super server, server and client on three levels, the DB2 product family database products on different platforms outlined:
