Description Author

This class provides simple access to CSV files with the possibility to navigate through the record sets and also to manipulate them.

The access to the record sets is as easy as accessing the record sets of a normal SQL based database.

It just takes the file name of a file with information in the CSV format (Comma Separated Values) the class takes care of the other operations that you may want to perform, like for instance: navigating through the records in the file, updating records, deleting records and adding a new record.
