We know that the Object-Oriented Modelling (OOM) technique visualizes things in an application by using models organized around objects. Any software development approach goes through the following stages − Analysis, Design, and Implementation. In object-oriented software engineering, the software developer identifies and organizes the application in terms of object-oriented concepts, prior to their final representation in any specific programming language or software tools. Difference Between Structured and Object-oriented analysis : Structured Analysis Object-Oriented Analysis The main focus is on the process and procedures of the system. The main focus is on data structure and real-world objects that are important. It uses System Development Life Cycle (SDLC) methodology for different purposes like planning, analyzing, designing, implementing, and supporting an information system. It uses Incremental or Iterative methodology to refine and extend our design. It is suitable for well-defined projects with stable user requirements. It is suitable for large projects with changing user requirements. Risk while using this analysis technique is high and reusability is also low. Risk while using this analysis technique is low and reusability is also high. Structuring requirements include DFDs (Data Flow Diagram), Structured Analysis, ER (Entity Relationship) diagram, CFD (Control Flow Diagram), Data Dictionary, Decision table/tree, and the State transition diagram. Requirement engineering includes the Use case model (find Use cases, Flow of events, Activity Diagram), the Object model (find Classes and class relations, Object interaction, Object to ER mapping), Statechart Diagram, and deployment diagram. This technique is old and is not preferred usually. This technique is new and is mostly preferred.
