This is a short User's Guide to the Emdros Query Tool (aka eqt).

The Emdros Query Tool reads MQL queries and gives back the results in a way that makes sense in the context of your database.

Origins of the query tool

The original algorithms for the Emdros Query Tool were written by Hendrik Jan Bosman in Python. Thus he is the real father of the Emdros Query Tool. The algorithms were rewritten in C++ by Ulrik Petersen.
