Data::Fallback Description

Fallback through an array of levels till you find your data, cacheing where desired Data::Fallback is a Perl module to allow fallback through an array of levels till you find your data, cacheing where desired.The simplest, good example for Data::Fallback, is cacheing a database to a conf file, then to memory. In general, the user supplies an array ref of hash refs (an object property named list), where each hash ref explains how to get data for that step. Each hash ref needs a package, which currently can be Memory, ConfFile, DBI, or WholeFile. Update acceptance can be set for each level.Data::Fallback then goes through the array, checking for data, stopping when it finds said data, updates up the array, as requested, and returns the data.A group can be thought of as a row and an item a column.
