Yes, this is standard stuff. Apart from the documentation for the DBI module, you might also want to get "Programming the Perl DBI" from O'Reilly. It is quite old now but if you use simple DBI then it still tells you all you need to know about it and it is well written and has easy examples.
This may be all you need for a simple project but be aware of the fact that there are newer approaches to database interaction around, such as object-relational mapping, e.g. with DBIC which allow you to interact with a database without writing SQL queries. IMHO, if you are just getting started with this, you might as well learn DBIC instead of bare-bones DBI.
