Where we implemented two modes of exchanging the messages, the open mode, where the client sends and receives the data as cleartext, and the secure mode, where our TCP tunnel is protected using the Advanced Encryption Standard AES encryption algorithm to protect the traffic in the transit path.

The request for a service is actually a call to a function implemented in a procedure. Although CALL statements are usually associated with local functions - that is, procedures that execute on the same machine as the calling program - they can equally be associated with remote functions that execute on a different machine.
These are outlined below. A typical approach is to split the logical functions of the application into three:. Conceptually, each of these three areas of functionality - or layers - are handled by separate programs. The user interface logic is always handled by the client application. If the client application handles only the user interface logic, it is called a thin client.
Sometimes some, or even all, of the business logic is also handled by the client application; this is called a thick client. In a distributed computing environment, each of these programs might run on different machines - but they would work equally well if they were all running on the same machine. A Web application is the ultimate thin client. The user interface is handled entirely by the user's Web browser.
