with tools I mean, SQL or Access... since I am not way too familiar with them but I know they could produce databases adn ACCESS could also give interfaces as well as VB ...so if i could achieve the same using Perl from the scratch, building a database until generating and maintaining such reports from this database and all that
Oh absolutely NO. Why to reinvent wheel if it's already there. I thought you are parsing files and inserting data into databases.
Use third party tools. there are lot of them.
