Processing Requests

The server can process SQL requests. This enables it to support a wide variety of client applications that use SQL and for those clients, SQL is the standard access language for requests to all relational and non-relational data.

In addition, the server has its own 4-GL request language called WebFOCUS that provides a much more robust set of features than SQL and extends the types of requests that can be processed, especially requests against non-relational data sources whose architecture is not based on the relational model.

The server in client/server architecture is used for data access and manipulation. The server receives a request for data, processes it, and returns an answer set or message to the client. Adapters are among the various subsystems that comprise a server.
