Enterprise Application Integration
Many Enterprise applications have evolved rather than being planned and designed, resulting in monolithic systems running on disparate platforms. IBM's SNA/RJE (Remote Job Entry) and TCP_IP/FTP (File Tranfer Protocol) were some of the earlier synchronous technologies that acted as an information bridge between application systems. Another type of communications method was to use synchronous message-based connection-oriented method like RPC's. A need for asynchronous delivery systems spawned the advent of Message Oriented Middleware (MOM) - these products provide an assured, asynchronous and connectionless method to exchange messages (business transactions) between processes. Growing data security requirements has facilitated the use of Internet Web Services for information exchange.

We at Technical Data Services have had extensive experience in the following:

• Internet Web Services for the Microsoft and Sun Microsystems technologies
• IBM's MQ Series for s/390, UNIX and Windows
• Microsoft's MSMQ for Windows
• SOAP/XML/HTTP, RPC, FTP, SNA/RJE, SNA/LU6.2
