You need to install the CGI::Application module, it's a framework, not an application. See the Documentation, the CGI Application website and A Tutorial for CGI::Application from the tutorials section to learn how to use it.

Actually if you are new to CGI programming have a look at some of the posts from Web Programming and Ovid's CGI Course.

Perhaps learning Perl (not 'PERL') would be a useful first step. Then, realizing that CGI::Application is a module rather than an application (despite having the word in the name), and reading and understanding its documentation would start you in the right direction. Last, but perhaps in some ways most important, writing the necessary code and showing it here if and when you run into problems would be a really good approach.

The question you're asking is too broad to have a trivially easy answer.

Well, first of all, that module doesn't interact with databases.

As for steps for interacting with a database, here you go:

1. Determine what database you're using. (MySQL, Oracle, etc.)
2. Install the DBI module if it is not already installed. (Looks like you don't have to worry about this step.)
3. Install the appropriate DBD module that works with your database. (Ex: DBD::mysql for MySQL, DBD::Oracle for Oracle, etc.)

That's the general idea of what to do. Since I haven't tried connecting to databases yet, there's a chance that more experienced monks might point out things that I missed.

You missed the part where you study 'perldoc DBI' until you're ready to fall over, and then give up programming forever to become a mercenary in the wild African jungles because it's a much easier way to make a living. Otherwise, you've got it spot on. :)

# Or it can be as easy as...
perl -MDBI -wle 'print for DBI->connect("dbi:mysql:foo")->selectrow_ar
+ray("SELECT * FROM xyz")'
