ADOxx is a development and configuration platform for implementing full-fledged modelling tools. It supports the implementation of individual modelling languages, modelling procedures and corresponding functionalities like visualisation, simulation, queries or transformation. ADOxx® applies the meta-modelling approach, thus enabling quick development of professional modelling tools. Implementation background is a configuration approach for the modelling language and a scripting approach for the functionalities. Resulting modelling tools are compiled from vast available functionalities like persistence, user management, a complete model editor, querying, simulation and import/export transformation as well as from scripted functionalities and individual add-on implementations.
