How system analysis and design is different from object oriented analysis and design?

∙ 12y ago
System analysis and design (SA&D) and object-oriented analysis and design (OOAD) are two different approaches to the development of computer-based information systems.
SA&D is a traditional approach that focuses on understanding the requirements of the system, analyzing the current system, and designing a new system that meets those requirements. It is a process-oriented approach that typically involves creating a detailed specification of the system before beginning development.
On the other hand, OOAD is a modern approach that focuses on modeling the system as a collection of objects that interact with each other to achieve the desired functionality. It is a more object-oriented approach that involves designing a system by first identifying the objects in the system, their properties, and the relationships between them.
Some of the key differences between SA&D and OOAD are:
Focus: SA&D focuses on the process of designing a system, while OOAD focuses on the objects in the system and their interactions.
Design: SA&D is typically a top-down design approach, while OOAD is a bottom-up design approach.
Requirements gathering: SA&D emphasizes the gathering of requirements and creating detailed specifications before beginning development, while OOAD emphasizes rapid prototyping and iterative development.
Abstraction: OOAD relies heavily on abstraction, while SA&D relies more on specific details and processes.
Overall, both SA&D and OOAD are valid approaches to the development of computer-based information systems, and the choice between them depends on the specific needs and requirements of the project.

Attributes in class hierarchy in object oriented analysis and design?
Analysis means finding the exact scenario for the problem and design means finding the main class from the analysis part an d to give operation for that class. and from that we can know the exact process.

The difference between Structured Analysis/Structured Design (SA/SD) and Object modeling technique (OMT) is primarily a matter of style and emphasis. In the SA/SD approach, the functional model dominates, the dynamic model is next most important, & the object model least important. In contrary to this, OMT modeling regards the object model as most important, then the dynamic model, & finally the functional model.The Structured Analysis/Structured Design approach organizes a system around procedures. On the contrary, an object oriented design technique organizes a system around real world objects, or conceptual objects that exist in the user's view of the world. Most changes in requirements are changes in function rather than in objects, so change can be disastrous to procedure based design. By contrast, changes in function are readily accommodated in an object-oriented design by adding or changing operations, leaving the basic object structure unchanged.An SA/SD design has a clearly defined system boundary, across which the software procedures must communicate with the real world. The structure of a SA/SD design is derived in part from the system boundary, so it can be difficult to extend a SA/SD design to a new boundary. To the contrary, it is much easier to extend an object-oriented design.In SA/SD the decomposition of a process into sub-processes is somewhat arbitrary. Different people will produce different decompositions. In the object-oriented design the decomposition is based on objects in the problem domain, so developers of different programs in the same domain tend to discover similar objects. This increases reusability of components from one project to the next.The object-oriented approach better integrates databases with the programming code. One common uniform paradigm, the object, can model both database and programming structure. In contrast, a procedural design approach is inherently awkward at dealing with databases.
