A system and method for organizing and classifying existing applications so as to enable users to create new applications using the one or more parts of existing applications. The system is capable of automatically generating a large number of template applications which are fully designed, coded, and ready-to-use. The system also automatically expands its catalog of template applications and screen components, which are categorized based on a specified purpose, whenever a user creates a new application or screen with the same purpose. In this way a user can simply specify the purpose of what they want to create, and the system will provide a ranked list of possibilities based on the actions of other users, and automatic generation mechanisms.
