Developing the work ‎mechanism in ‎educational ‎institutions is one of ‎the most important ‎factors that affect ‎the quality of ‎education and its ‎outcomes. The ‎effective work ‎mechanism ‎contributes to ‎improving efficiency ‎and productivity. In ‎this work, the ‎database stored in ‎‎(The representative ‎of the Iraqi Ministry ‎of Education in Erbil ‎‎/ Specialist ‎Supervision Unit) is ‎transformed into a ‎system for managing ‎the data warehouse ‎of the educational ‎institution by ‎exploiting the ‎database available in ‎the institution and ‎linking this data. By ‎identifying the ‎necessary presences ‎in this system and ‎representing the ‎relationships ‎between the ‎presences to ‎facilitate the process ‎of extracting, ‎converting, and ‎uploading this data ‎to the system ‎designed for the ‎purpose of taking ‎advantage of modern ‎technology to ‎support the decision ‎maker in this ‎educational ‎institution. The ‎proposed system ‎helps the ‎institution’s director ‎quickly access and ‎review historical ‎data on a specific ‎subject and analyze ‎it for the purpose of ‎making strategic ‎decisions related to ‎the educational ‎process according to ‎the available ‎information ‎accurately and ‎without fatigue or ‎boredom.‎
