NAME
Maplat::Web::UserSettings - save and load user/module specific data
SYNOPSIS
This module provides handling module-specific data handling on a per user basis
DESCRIPTION
This module provides a simple interface to the PostgreSQL database for saving and loading module specific data on a per user basis. It can, for example, be used to save user specific filters to the database. It can handle complex data structures.
In the background, it uses Storable and Base64 to store complex data structures and text in a database text field. This avoids having to play around with blobs.
