This forces OOA to combine all behaviors , characteristics , and states together into one analysis process, rather than splitting them up into separate stages, as many other methodologies would do.

For example, a typical implementation of OOA is to create an object model for an application. The object model might describe the names , relationships , behaviors , and characteristics of each object in the system. With this information established for each object, the design process that follows is much simpler. The process of object-oriented design is really just an extension of the object-oriented analysis process that preceded it, except with a critical caveat: the consideration and implementation of constraints.

For example, with an analyzed object in hand, such as an object model , we must now consider how that object would actually be designed and implemented, which will often require the application of constraints, such as software or hardware platforms, time and budgetary limitations, performance requirements, developer aptitude, and so forth.

Put another way, the OOD process takes the theoretical concepts and ideas planned out during the OOA stage, and tries to find a way to design and tangibly implement them, usually via code using whatever language and platforms the development team has settled upon.

What is meant by class diagram? A class diagram is an illustration of the relationships and source code dependencies among classes in the Unified Modeling Language UML. In this context, a class defines the methods and variables in an object, which is a specific entity in a program or the unit of code representing that entity.

What do you mean by OOP? Object-oriented programming OOP refers to a type of computer programming software design in which programmers define the data type of a data structure, and also the types of operations functions that can be applied to the data structure.

What do you mean by Data Design? Database design is the organization of data according to a database model. The designer determines what data must be stored and how the data elements interrelate.

Database design involves classifying data and identifying interrelationships. This theoretical representation of the data is called an ontology. What does SDLC stand for? What are the three main types of models?
