All the classes in the system are related with each other.

Structured Vs. Object Oriented Analysis and Design SAD Vs. OOAD

Chapter 8 Slide 1 System models. A polymorphic object is one who true type hides within a super or parent class.

These blueprints can then be transferred into code using any specific OO language. Essentially, a message is a function or procedure call from one object to another.

Chapter 14 Slide 1 Object-oriented Design. Also known as system unit.

It focuses on essential characteristics of an object relative to perspective of user. Auth with social network: Use case diagrams and Class diagram. Sequence diagrams Sequence diagrams are part of the UML and are used betweeh model the interactions between the actors.


Will be covered in this course 2- OR Object Models: For example, finding address of a particular employee. An investigation of the problem rather than how a solution is defined. Sequence diagrams, which show interactions between actors and the system and between system components.

The waterfall model is a sequential design process, often used in software development processes, in which progress is seen as flowing steadily downwards like a waterfall through the phases of Conception, Initiation, Analysis, Design, Construction, Testing and Maintenance.

OK 1 M Chapter All tangible entities student, patient and some intangible entities bank account are modeled as object. Ad is defined as set of specifications created and distributed by Object Management Group.

UML use activity diagram instead. This phase also identifies and defines the additional classes or objects that support implementation of the requirement. They are controlled by the data input to the system, with relatively little external event processing.

Difference between Structured Analysis and Object Oriented Analysis? – ppt video online download

It can further define a use-case and make use-case modeling much easier. UML is a visual language that bdtween you to model processes, software, and systems to express the design of system architecture. It indicates that two classes are similar but have some differences. The spiral model is intended for large, expensive and complicated projects. It is an activity that occurs during certain software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.


It is suitable for most business applications, game development projects, which are expected to customize or extended. During OO analysis, there is an emphasis on finding and describing the objects or concepts in the problem domain. It applies to both objects and operations. Sequence diagram for View patient information.

Chapter 6: Structured Vs. Object Oriented Analysis and Design.

UML diagrams represent dynamic model include sequence diagram, communication diagram, state diagram, activity diagram. It allows improvement or modification of methods used by objects without affecting other parts of a system.

These models are useful in a wide variety of disciplines in the physical, biological and social sciences. State diagrams, which show how the system reacts to internal and external events. Registration Forgot your password? And implemented using any OO programming language; e. The spiral model is a software development process combining elements of both design and prototyping-in-stages, in an effort to combine advantages betweeh top-down and bottom-up concepts.
