Application Integration Issues Deny Companies Maximum Benefit From Investments In IT

By Peggie K. Lambert


Enabling the communication of the vast array of different applications normally found in larger companies is a huge problem. When old mainframe legacy systems are part of the equation, data transfers between applications can become extremely complex and require expert support. In fact, large amounts of Of the efforts and and expenses of modern Information Systems departments are swallowed by the bottomless pit of application integration.

While middle ware exists to help overcome these issues, the permutations of languages, equipment, databases, and operating system are never ending, so it is impossible to cater for every eventuality. If proprietary tools are not available, the the solution is a home-grown procedure to do the job of communicating between systems. Here the skills shortage may affect the maintainability of such software bridges.

The advent of the concept of object orientation seemed to promise some relief. Unfortunately this did not address the problem. Only if there is only one occurrence of any data, with all applications accessing it directly would the problem be obviated. As long as there are Application specific databases, the problem will persist.

However, packaged solutions would still depend on their unique databases. This means so there will still be considerable redundancy, necessitating communication via some form of middleware. With packages often being preferred, there is really no solution in sight for this dilemma.

What is needed to resolve the situation today is a situation where an enterprise database with standard modules to update, maintain, and query the common data is created. Any new applications would then simply interface with that central database. Application specific data could be integrated with the enterprise database or kept separate, as appropriate.

Such a simplified view of company date is still completely futuristic. The power of computer hardware makes it possible for inefficient. Sub-optimal configurations to survive. Perhaps the IT professionals could learn from manufacturing, where the lesson was learned long ago that keeping older, inefficient, machinery because it had been paid for and was still work was an ineffective approach, which lowers quality and productivity.

In any company, a lot of effort goes int application integration. Because the complexities may be too much to handle, many organizations simply accept the situation and live with the multiple capturing of data. It is to be hoped that some rationalization will occur as the Computer software industry matures. Perhaps future Information Professional will be amazed and the current haphazard approach to such an important business function.
