A client application is a program that accesses a data server.
When the data server is Adaptive Server, applications can be programs created with Open Client Client-Library™ or DB-Library™, Embedded SQL™, or any other front-end development tool that is compatible with the Open Client/Server Interfaces™ (C/SI) such as PowerBuilder®. Open Client/Server includes routines and protocols for client/server communications.
In a simple replication system, clients update primary databases and Replication Server updates replicate databases. By replicating stored procedures, clients can update primary data from any replicate database.
