Easy Query Builder (EQB) - is a free program which allows you to create SQL queries to your database in a user-friendly way. You don’t need to know SQL or any other complex query language - all your requests can be described visually, very easily, and in (almost) natural language.

FriendlyData lets you communicate with databases using natural language. With simple statements like "Show me users from Europe", it simplifies what otherwise involves writing potentially complex SQL strings.
