There may also be different categorizations that you may use so you can find the employees you need easily. For example, you may come up with a category wherein the people from one department will be lumped together depending on the specification that you will choose.

That said, there are plenty of training videos out there for those who want to learn how to do this on Oracle or in other programs that use tables to keep track of information. Most of these videos are up on YouTube and done by people who mean well, but the companies typically have FAQ or tutorial pages that will offer in-depth help if asked.
