Flatfile

The Flatfile package is designed to be a simple, light method of storing and retrieving data in tables with SQL-like features. All data is stored in tab-delimited text flat files. It supports a very powerful and extensible WHERE clause mechanism, which can be used with SELECT, UPDATE or DELETE statements. It can do ORDER BY on any number of fields, and includes full documentation with examples that should have you up and running in a couple of minutes.
