After reading this week's article, "Modeling for the Future," expand on the subject of Database Modeling. There are several tools listed and reviewed in the article. Research these tools further (or identify other commercially available modeling tools), compare three tools, and apply your findings as if you were selecting one of the tools for use at your place of employment. Be sure to include comparative detail information on implementation scenarios, target industries, company types most suited for the tool, costs, software type, the type of operating system required, and the target user population.
