Abstract: A web portal architecture for implementation in private universities in Nigeria was proposed and described in this paper. The waterfall model was adopted as the methodology of choice where it prescribes a systematic approach to software development which helps to clearly define both the user and system requirements, The portal proposed was developed using several development tools such as WAMP packages where the Windows platform is the operating system on which the portal runs, Apache is the server, while MySQL was used for the database and PHP as the scripting language. A model of the portal was designed using modeling tools such as Data Flow Diagram (which included student level data flow diagram, lecturer level data flow diagram, administrator level data flow diagram) and the Use Case Diagram. This was preceded by the implementation of the portal to achieve specific objectives such as controlling educational processes, providing access to educational resources, storing user details and information, ensuring security and data integrity, providing a user friendly environment for users and confidentiality.
