Students admission to the Iraqi educational institutions suffers continually from being a slow paced process, in which, students have to do lots of paper work, that requires them to be precise and careful not to make any mistakes. Additionally, the process is time and effort consuming for the employees involved in the preparation and organization of the required materials, as well as, being money consuming for the Ministry of Higher Education. This research addresses the problem statement, and provides an internet based solution, that aims to facilitate admissions by fully automating the whole process, and eliminating the paper work needed by system users. The developed solution is given the abbreviation OASIS which stands for (Online Admission System for Iraqi Students). OASIS consists of four different modules: the Visitor module, which provides visitors with the ability to view current admission status. The Student module, which provides students with the ability to apply for the Iraqi educational institutions online, in addition to save, load and submit their wish lists. The Operator module, which enables operators to manipulate student’s data. Finally, the Administrator module, which enables system administrators to nominate students. The established automation system is in the form of a Rich Internet Application, which is considered to be a new category of applications that resembles to desktop applications. It is supposed to enhance user experience by providing him with the feeling that the application behaves like a typical desktop application where no page refreshes are required.The development of the proposed system was conducted using Adobe Flash Platform, which is an integrated set of tools and technologies from Adobe corporation. OASIS was developed using Adobe Flash Builder 4.0 Premium, with ActionScript 3.0 and MXML as the main programming languages, and an architectural framework called Swiz, for architecting the application.
