Functional and Object-Oriented Methodology for Analysis and Design

The chapter provides an overview of FOOM–Functional and Object-oriented Methodology–for analysis and design of information systems. FOOM integrates the functional and object-oriented approaches. In the analysis phase, two main models are created: a) a conceptual data model, in the form of an initial class diagram; and b) a functional model, in the form of OO-DFDs (object-oriented data-flow diagram). In the design phase, the above models are used to design the following products: a) a complete class diagram, including Data, Menus, Forms, Reports and Transactions classes, including their attributes, relationships and methods; b) the user interface–a menus tree; c) the input and output form and report; and d) detailed descriptions of the class methods, expressed in pseudo-code or message charts
