Release 10.1A: OpenEdge Getting Started:
Database Essentials

System platform

The OpenEdge RDBMS provides a multi-threaded database server that can service multiple network clients. Each server handles many simultaneous requests from clients. The server processes simple requests as a single operation to provide rapid responses; it divides complex requests into smaller tasks to minimize the impact on other users of the database. OpenEdge supports a variety of hardware and software platforms to suit any configuration need.
