From the developer:
Navicat for SQLite is a powerful Database administration and development tool for SQLite. It works with SQLite version 2 and 3 and supports most of the SQLite features including Trigger, Index, View, and so on. Features in Navicat are sophisticated enough to provide professional developers for all their specific needs, yet easy to learn for users who are new to SQLite.
