Various embodiments are directed towards a platform for rapid development of applications. A data processing application may be generated by applying templates, work streams, change entries, and user modifications to generate data processing applications. In at least one of the various embodiments, the applications may be generated based project initial instructions and by receiving and processing example data in combination with templates, change entries, and work streams. Further, in at least one of the various embodiments, modifications made to the generated applications may be preserved as change entries associated with a work stream. In at least one of the various embodiments, separate applications may be generated based on the work streams and/or change streams of other applications. In at least one of the various embodiments, if a generated application may be modified a new revision number may be associated with the modified version of the application.
