Method and system for creating queries for complex data structures

A method for creating queries for complex data structures, comprising:

• providing a graphical user interface accessed via a computer, the graphical user interface including a tree domain and a query area;
• linking the graphical user interface with a database populated with data relating to a manufacturing process, the graphical user interface including a tree domain having a tree representation of structure of the data populating the database, wherein the tree representation includes graphical representations of attributes and/or structural-elements relating to the manufacturing process and populating the database;
• dragging and dropping selective graphical representations from the tree domain to the query area where selected graphical representations are converted to a query based upon operators linking the selected graphical representations dragged and dropped from the tree domain.
