The belief is that the enterprise could benefit from the existing data, so don't simply overwrite data and lose it forever; keep it around in an organized and structured historical repository for specific strategic analysis. With the arrival of portable and mobile wireless systems, organizations are now looking at offering their information on PDAs. Employees would then have access to a wide range of information anytime, anywhere, giving them access to a plethora of past information. For example, if a salesperson could download his firm's available inventory and his specific client's past purchases, he could certainly benefit from a projected purchasing trend analysis as well as promising product shipping and delivery based on goods on hand.

The next step is to connect to the database. How does one actually connect to the database? If you've ever been unable to connect to your data, you know what we're saying here. It's a pain. You don't know why, you can't figure out what's happening since you've been following the same simple steps for who knows how long, and yet all of a sudden, you can't access the data. Whom do you call, how long will this takeyou're stuck. End users are usually nontechnical, and when they can't continue with business due to a technical error, you have problems.

The bonus here is that the user would be using two computers instead of one. The end−user workstation would retain information since it would have increased memory. The front−end programs could run on the workstation, leaving the main computer free for the already increasing workload from the ever−increasing number of end users. This is when we should have all invested in Microsoft, Intel, Cisco, and IBM. These people really changed the world. IBM was first trying to enhance the dumb terminal, and at the same time was building personal computers for individual usage.
