in reply to loading csv file in berkeley data base using perl
Hi there and welcome to perlmonks.
Likely what you're being asked to do is to transfer data that is formatted as comma separated values inside of a text file into another type of data store known as a Berkeley database. Putting the data into such a database lets you query and change the data with the features provided by that database system.
You could find a module on CPAN such as Text::CSV that will help you read in CSV data from a text file. There are other modules such as BerkeleyDB that give you a way to write that data into a Berkeley database.
You can always ask back here with specific questions if you get stuck on something.
