One of the more intriguing issues prevailing throughout the last few decades of campus system research is the question of how to achieve a flexible and efficient curriculum system. More recently, the enterprise solutions have shifted to campus systems due to the academic global competition that is in a state of constant change. In this paper, several different levels of integrations are introduced and a practical campus curriculum system consisting of a course preparation system, a course enrollment system, and an assessment system is presented. The core considerations of the proposed architecture are flexibility and performance; besides, the evaluation and measurement are also under discussion.
