The Model Concept

infoTOWN Visual Query Builder functions are based on "Models". A Model is a graphical representation of a database, or part of a database. Queries are built using the fields of a Table in the Model.

 

A Join is made represented by an arrow indicating the direction of movement.

The direction of the join determines the direction in which infoTOWN Visual Query Builder generates the SQL text.
