Abstract

Embodiments of the invention relate to deploying a program module. The deploying includes obtaining a data dependency relationship between the program module and multiple to-be-deployed program modules, and a specific start order. In response to a request to install and configure the program module, data on which the program module depends are identified according to the data dependency relationship. In addition, the program module is installed and configured responsive to the identified data. The program module is started in response to completion of a startup of program modules required to be started before the program module as specified by the specific start order.
