A software framework has been developed for the DArk Matter Particle Explorer (DAMPE) mission, a satellite based experiment. The software framework of DAMPE is mainly written in C++ while the application under this framework is steered in Python script. The framework is comprised of four principal parts: an event data model which contains all reconstruction and simulation information based on ROOT input/output (I/O) streaming; a collection of processing models which are used to process each event data, called as algorithms; service module, a series of common tools which provide general functionalities like data communication between algorithms; and event filters. This article presents an overview of the DAMPE offline software framework, and the major architecture design choices during the development. The whole system has been applied to DAMPE data analysis successfully, based on which some results from simulation and beam test experiments are also shown in this article.
