As the development of E-enterprise, the strategy of traditional MIS management needs to change. Because the access control and deployment of software is an important issue we need a reliable and user-friendly interface to manage. We bring up an idea of the infrastructure of software dispatch in enterprise and realize the module by Information Resources Management System (IRMAS). Instead of operating by console, we provide the system which contains the following features: 1. Web based system; 2. Centralized management; 3. Security and trust mechanism; 4. Large scale and high performance. We recognized that the infrastructure is reliable and realizable.
