INFIS

• experimental integration platform for C2 information systems

• test bed for the German part in the context of the ATCCIS (Army Tactical Command and Control Information System) study and MIP (Multilateral Interoperability Programme)

• platform independent access

Why UML?

• UML = Unified Modeling Language

• understood by most of other interesting people

• nearly formal meaning

• standardized by Object Management Group

• automatic Code Generation by CASE-Tools

How to continue?

• Redesign the complete system, such that only the application level has to be extended in further extensions

Build your own application server

• Use new techniques and buy an application server
