Applicability of object-oriented design to large MIS projects

<p>Previous functional decomposition design methodologies such as Structured Design, Top-Down Design and Bottom-Up Design cannot support the design of large, reusable, maintainable, complex systems. Unlike functional decomposition approaches mentioned above, object oriented design (OOD) methodologies do not seek to break a large problem into smaller, more solvable pieces. Instead, they identify those objects and operations in the real world which must be manipulated to implement a design solution to the user's problem. The purpose of this thesis is to investigate the applicability of object-oriented design (OOD) methodology for large Management Information System (MIS) projects. Furthermore, it will propose a new OOD approach called Extended OOD (EOOD) and it will test its practicability by applying the new design approach to an MIS model.</p>
