Object-Oriented Analysis (OOA)
Object-Oriented Analysis is the initial phase of the software development process, where the primary focus is on understanding the problem domain, capturing and modeling the requirements, and defining the system’s behavior. OOA is all about abstracting real-world concepts and entities into a software model, and it involves the following key aspects:
- Problem Domain Understanding: During OOA, the software engineer works closely with domain experts and stakeholders to understand the problem that the software it intended to solve. This involves gathering requirements, identifying stakeholder’s needs, and understanding the business processes.
- Use Case Modeling: Use cases are used to define the interactions between various actors (people, others systems, etc.) and the system. Use case diagrams are a common tool to represent these interactions, helping to capture the system’s external behavior.
- Domain Modeling: Domain modeling involves identifying and defining the core concepts, objects, and entities in the problem domain. It typically results in the creation of class diagrams, which represent the relationship and attributes of these entities.
- Analysis of Behavior: OOA also considers the behavior of the system, often through activity diagrams, sequence diagrams, and state diagrams. These diagrams help depict how objects interact and the flow of information and control in the system.
- Identifying Constraints: Constraints, both technical and non-technical, are important to consider during OOA. These may include performance constraints, regulatory requirements, and technology limitations.
- Non-Functional Requirements: During OOA, non-functional requirements such as performance, scalability, security, and maintainability are identified and documented.
- Documentation: All the analysis work is documented, which may include various UML diagrams, use cases, textual descriptions, and other artifacts to ensure that the system’s requirements are well-understood.
Object Oriented Paradigm in Object Oriented Analysis & Design(OOAD)
There are two important steps in creating such software. Object-Oriented Analysis (OOA) and Object-Oriented Design (OOD). These steps are like the building blocks for creating software.
