This book is about a web application viewed as a Staff/Students on-line Assessment information system that enables students to assess their lecturers online and vice versa. The application encompasses a normalized database tables and application program that guarantees the database-user interactivity. This application is built using PHP, HTML, Java Script and MySQL. HTML presents the Front-end design, PHP and sql establishes the connectivity and interactivity. MySQL constitutes the back-end, which is the database itself.The book is written in a simple, easy-to-read style and contains examples to illustrate a certain problem solving. It is an excerpt of my BSc Project. It also contains practical demo procedures and outputs to test the reader's grasp of learners' practical perception.
