SQL's a good example <a href="https://stackoverflow.com/users/6741/michael-dorfman">Michael Dorfman</a> gave. Others I have used extensively are: <ul> <li><a href="http://www.cs.nmsu.edu/~rth/cs/cs177/s98/IntroUIL2.html" rel="nofollow noreferrer">UIL</a> - GUI building</li> <li><a href="http://www.gnu.org/software/make/" rel="nofollow noreferrer">Make</a> - program building and installing</li> <li><a href="http://www.regular-expressions.info/" rel="nofollow noreferrer">regexp</a> - String pattern matching</li> <li><a href="http://dinosaur.compilertools.net/" rel="nofollow noreferrer">lex and yacc</a> - lexical analyzer and compiler creation</li> </ul> As for how it works out, I think it depends on the language and the domain. UIL is out-and-out awesome for specifying GUI's. If you do the same thing in inline Motif code, GUI specification errors that the UIL compiler catches look like perfectly compilable code to a C or Ada compiler. That causes tons more time to be wasted debugging. Plus, it just plain looks uglier in general-purpose code using Motif API calls. Make can really get to be a nightmare, but there aren't a lot of tools out there that can do what it does, and I suspect they all have the same problem. Regular expressions are unneeded for very simple tasks, and a nightmare for really complex ones. For those in the middle, they are a wonderful tool. Lex and yacc can be quite helpful. However, a person who knows what they are doing can create parsers and lexical analyzers by hand with about the same amount of work.

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.
