For a BUG tracking software it is essential to have:

Reporting facility - complete with fields that will let you provide information about the bug, environment, module, severity, screenshots etc.

Assigning - What good is a bug when all you can do is find it and keep it to yourself, right?

Progressing through the life cycle stages - Workflow

History/work log/comments

Reports - graphs or charts

Storage and retrieval - Every entity in a TESTING process needs to be uniquely identifiable, the same rule applies to bugs too. So, a bug tracking tool must provide a way to have an ID, which can be USED to store, RETRIEVE and ORGANIZE bug information.
