Disk-based data structures (DBM)

December 18, 2000

Relational databases are powerful, but often large and bulky to work with. Like trying to parallel park a Ford Explorer, sometimes you just have too much tool for the job.

We've discussed the interaction between Perl and relational databases, courtesy of the DBI module, in several installments of the Perl You Need to Know. But suppose you don't want to get tied up with a relational database and all the supporting software needed, yet you still need to store a dataset to disk for future use. This month we'll look at several Perl DBM, or database management, solutions which have much less overheard than DBI and are a quick way to store and use Perl data structures to and from disk.
