Legacy application portfolios are often tremendously complex, with hundreds of thousands of elements connected in many different ways. Programs call subprograms, initiate jobs, read and/or write database tables, use flat files ... and these are just a few of the more common types of connections. Analyzing these connections becomes critical when planning complex modernization projects. The following are typical of the questions that can arise:

• "We have six main applications. If we move one specific application off the mainframe, which connections will be affected?"
• "Once this application is off the mainframe, we will have to establish a data transfer mechanism to keep it in sync with the mainframe database. Which read-only data could be mirrored off the mainframe to simplify the transfers?"

Trinity Millennium Group has developed powerful tools that enable this type of analysis. We catalog all application elements and the connections between them, and then provide a variety of visualization capabilities. We can analyze the connections for a particular application element, or for a larger group of elements treated as a "cluster." For example, answering the sample questions above involves treating a given application as a cluster. The following diagram is one type of visualization that results from such analysis. The numbers on the arrows show the quantity of connections between various clusters of elements.
