Integration With Existing Systems

In the following figure, the existing academic information system of a university is abstracted by the blocks labeled UNIV database and UNIV Enrollment System, while HEEDS is represented by the Automated pre-registration block.

No changes may be necessary in the existing university system to take advantage of the functionality of HEEDS. The existing enrollment system and HEEDS communicate through XML files: this manner of information exchange keeps the systems as separate entities. Scripts only have to be written for data exchange. The overall integration strategy is outlined by steps 1 3 in the figure. The MIS office of UNIV will be responsible for creating the scripts in Step 3.
