I agree with Mitch. I would add that you should decide whether you want to do an integration test or a unit test (or both, but not in the same test). If, in fact, you do want to do a unit test, realize: <ol> <li>Your code has a "dependency" on an external database.</li> <li>When unit testing you'll have to find a way to "fake" the database. You want to test a "unit" which means a single thing, not two or more things (i.e. your CRUD code AND your connection to a database AND the database itself).</li> <li>Typically you'll need to refactor your code using something like dependency injection so that when unit testing you can fake things that your code depends on.</li> </ol> Unit testing isn't just testing your code. That's actually the easy part. The harder part is making your code testable. I recommend going to <a href="http://artofunittesting.com/" rel="nofollow">http://artofunittesting.com/</a> and watching the free videos on the right side under the heading "Unit Testing Videos". Forget the fact that he's working in .NET as it's the principles that are important. Then watch the GoogleTechTalks by Misko Hevery where he explains why you want to do dependency injection. <a href="http://www.youtube.com/watch?v=acjvKJiOvXw" rel="nofollow">Design Tech Talk Series Presents: OO Design for Testability</a> <a href="http://www.youtube.com/watch?v=wEhu57pih5w" rel="nofollow">The Clean Code Talks -- Unit Testing</a> (He has more too. There is a <a href="http://www.youtube.com/playlist?list=PLD0011D00849E1B79" rel="nofollow">series of six GoogleTechTalks</a>.)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
