Knowledge Fragments

Simple, unconnected knowledge fragments can be used as a personal
journal or a diary, aided by the calendar interface, and you can use
the full-text search facility to find and retrieve the information.
However, as you connect ('relate') knowledge fragments to one another,
the knowledge in your database becomes more useful and valuable.
Structurally the relationships between fragments resemble a network;
this is less limiting than other types of relationship such as the
tree structure, where each node can only have one parent. Piggydb
allows relationships between fragments to be as complex as you need.
A well-built network of related fragments can be navigated easily
using the Tree View, and arbitrary parts can be viewed using the
Document View which renders in a "printer-friendly" format.
