Structured Analysis treats processes and data as separate components versus object-oriented analysis combines data and the process that act on the data into objects. http://www.dbar-innovations.com

∙ 13y agoObject-oriented analysis (OOA) looks at the problem domain, with the aim of producing a conceptual model of the information that exists in the area being analyzed. Analysis models do not consider any implementation constraints that might exist, such as concurrency, distribution, persistence, or how the system is to be built. Implementation constraints are dealt during object-oriented design (OOD). Analysis is done before the Design
The sources for the analysis can be a written requirements statement, a formal vision document, interviews with stakeholders or other interested parties. A system may be divided into multiple domains, representing different business, technological, or other areas of interest, each of which are analyzed separately.
The result of object-oriented analysis is a description of what the system is functionally required to do, in the form of a conceptual model. That will typically be presented as a set of use cases, one or more UML class diagrams, and a number of interaction diagrams. It may also include some kind of user interface mock-up. The purpose of object oriented analysis is to develop a model that describes computer software as it works to satisfy a set of customer defined requirements.
Object-oriented design (OOD) transforms the conceptual model produced in object-oriented analysis to take account of the constraints imposed by the chosen architecture and any non-functional - technological or environmental - constraints, such as transaction throughput, response time, run-time platform, development environment, or programming language.
The concepts in the analysis model are mapped onto implementation classes and interfaces. The result is a model of the solution domain, a detailed description of how the system is to be built.

What is full form of abbrevation OOAD?
Object Oriented Analysis & Design
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.
Difference between links and association in object orinted analysis and design?
link is related to objects whereas association is related to classes
How system analysis and design is different from object oriented analysis and design?
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.

What is the difference between job design and analysis?
Quite simply;a job analysis is what could've been bettera job evalution is what actually the job is like
What have been the strongest influences on programming language design over the past 50 years?
Object oriented analysis and design.
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.
What the difference between c and c plus plus?
The fundamental difference is that in C++ object-oriented programming (OOP) was added. C is a procedural language (that means. top-down structure design), where as C++, which is an extension of C itself, is an object oriented language.
What is difference between Function Oriented Design and Obeject Oriented design?
In function oriented design a problem is thought in form of data and functions to manipulate those data. Both entities remain independent of each other. On the other hand in object oriented design a problem is thought in form of an encapsulated entity where both data and functions stay together in form of an object. Following link has a nice collection of articles of object oriented programming: http://cs-fundamentals.com/java-programming/java-programming-tutorials.php
