Host Database Standards

Although terminal access provides an appropriate interface to a wide range of host applications, most organizations also require applications that seamlessly integrate host data and applications with modern client/server and Internet-based information systems. Achieving this level of integration with IBM host systems begins with an understanding of the standards that support IBM host database applications.

IBM host applications often rely on an underlying database architecture provided by the host system. IBM uses the Distributed Data Management (DDM) architecture to provide a common language and set of rules for host data access. Programs adhering to this architecture can share data across multiple platforms.
