Induction – Free Mac OS X Database Client That Supports SQL & NoSQL
Induction is an open source and free tool for understanding and communicating relationships in data.
It can be used to explore rows/columns, run queries and visualize the data in several ways.
The tool has support for many databases including PostgreSQL, MySQL, SQLite, Redis and MongoDB. Also, any others can be added by writing new adapters.
Induction is currently in alpha and not a full-featured client yet but has a roadmap to become one.
