Nearly 70 percent of the world's data is stored in mainframe-based relational databases. Organizations that implement IBM mainframe and IBM AS/400 hosts need a way to let intranets, extranets, and Web users access data on those systems. A number of methods have been developed to provide host connectivity, including LAN-based access to mainframes, gateways that provide translation services, and Web technologies that provide a variety of middleware services.

More information about database connectivity in general may be found under the topics "DBMS (Database Management System)," "Middleware and Messaging," "MOM (Message-Oriented Middleware)," and "Multitiered Architectures."

This topic continues in "The Encyclopedia of Networking and Telecommunications."
