"Object oriented design is a method where developers think in terms of objects instead of procedures or functions. The overall system is designed keeping in view the interaction among objects that maintain the states and provide implementation on them. For implementing object oriented design three methodologies are adopted Object Modeling Technique (OMT), Structure Analysis/Structured Design (SA/SD), Jackson Structured Design (JSD). SA/SD approach is based on the data flow and JSD approach is action-oriented. Since SA/SD is easy to understand but it focuses on well defined system boundary whereas JSD approach is too complex and does not have any graphical representation."
