WOLD (Wizard fOr Leveraging the Development of multi-platform user interfaces) helps designers to produce running user interfaces to data bases of information systems simultaneously for multiple computing platforms. This software consists of a wizard application guiding designers step by step according to a mixedinitiative approach of production rules structured in a decision tree for choosing appropriate design options covering user interfaces to be produced. The main goal of this software is to speed up the development life cycle according to a transformational approach, spiral life cycle, derivation of user interfaces from data bases structure and queries, intelligent layout derived from data base structure and query. User interfaces are structured and described according to characteristics that remain independent of computing platforms.
