An application can communicate with a server through language commands. For Adaptive Server, the language is Transact-SQL. For Open Server, the language is whatever the Open Server has been programmed to understand. The application enters the commands into a command buffer, which the DBPROCESS points to. The application can place multiple commands in the command buffer, and the set of commands in the buffer is known as the command batch. The application then sends the command batch to the server, which executes the commands in the order entered in the buffer.
