Chapter 6: Structured Vs. Object Oriented Analysis and Design. – ppt video online download
Application development moves from custom development to assembly of pre-built, pre-tested, reusable software components that operate with each other. Need to define software objects and how they collaborate to fulfill the requirements. Chapter 1 Object Oriented Analysis and Design.
An investigation of the problem rather than how a solution is defined. This approach is old and is not preferred. About project SlidePlayer Terms of Service.
Chapter 6: Structured Vs. Object Oriented Analysis and Design.
A software development process is a structure imposed on the development of a software product. Assembly Modeling is technology and methods used by Computer-aided design and Product visualization differencce software systems to bbetween multiple files that represent components within a product. They are particularly useful during the analysis of requirements as they can be used to show end-to-end processing in a system.
The components within an assembly are represented as solid or surface models.
Use case diagrams, which show the interactions between a system and its environment. It defines the operation performed on objects. Also known as the spiral lifecycle model or spiral developmentit is a systems development method SDM used in information technology Betweeb. Objects with similar meaning and purpose grouped together as class.
Dynamic models identify the object needed and how they work together through methods and messages.
Difference between Structured Analysis and Object Oriented Analysis? – ppt video online download
Some people consider a lifecycle model a more general term and a software development process a more specific term. For example, adding a new employee. Without actually identifying objects, what are you going to interact with, and whose state will you change. Designs are implemented in a Programming Language.
In polymorphic operation, the operation may be carried out differently by different classes of objects. Chapter 8 Slide 1 System models September 29, This model of development combines the features of the prototyping model and the waterfall model.
Prior to the rise of OOM, the difterence paradigm was procedural programming, which emphasized the use of discreet reusable code blocks that could stand on their own, take variables, perform a function on sssad, and return values.
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. In the diffrence approach, the focus is on ooaad the structure and behavior of information systems into small modules that combines both data and process.
Object Oriented Analysis and Design. It is defined as set of specifications created and distributed by Object Management Group.
Object Oriented Approach
The objective of UML is to provide a common vocabulary of object-oriented terms and diagramming techniques that is rich enough to model any systems development project from analysis through implementation. It applies to both objects and operations. These show the processing steps as data flows through a system.
Sequence diagrams Sequence diagrams are part of the UML and are used to model the differenec between the actors. It stresses more on data structure and less on procedural structure.
For example, finding address of a particular employee.
DFD Context diagram shows the system boundaries, external entities that interact with the system, and major information flows between entities and the system. State diagram of a ssqd oven.
