Free query building software for windows

Korzh Query Builder (KQB) is a free tool that provides user-friendly graphical interface for building SQL statements, perform queries to databases and export the results into different formats.
You can describe your database data model only once and then do not worry about database design or table relationships - KQB will take care about that. You just describe your requests by creating natural English sentences and receive the results immediately.
KQB builds SQL SELECT statement according to users demand and database structure you define. It can build SELECT statements with sub-queries, with table aliases, with all kind of joins.
The tool can be used even by non-experienced users. If the data model is described then the users do not see real tables and real field names and see only the table names and field descriptions you want them to see. Operators can be spelled out (e.g. "is equal to" instead of mathematical symbols), field values can be replaced with descriptions (e.g. "MasterCard" instead of actual values like "MC") that makes interface more friendly.
