Hopefully to help a little ..

The data comes off of the database into an array, which is hashed using the column names determined earlier as keys. This gives a (temporary) hash with the following structure (called %tblData in the above):

$tblData{$columnname} = data from array

for each column name.

This then needs to be added to a permenent hash (called %tableData above) keyed on one or more of these column names, the keys being provided by the user. (it's part of a sub that takes a table name and list of keys and returns a hash). This should give the structure:

%{$tableData{$key1}{$key2}{$key3}} = %tblData

ie creating a hash of hashes which could be accessed using, for example,
my $data = $tableData{$key1}{$key2}{$key3}{$columnname}.
