Application development moves from custom development to assembly of pre-built, pre-tested, reusable software components that operate with each other. It is a standard language for designing and documenting a system in an object oriented manner that allow technical architects to communicate with developer.
UML is extensible and scalable. Download ppt “Chapter 6: We think you have liked this presentation. It focuses on essential characteristics of an object relative to perspective of user. This model of development combines the features of the prototyping model and the waterfall model. About project SlidePlayer Terms difderence Service. 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.
Software development and all of its activities including testing are an iterative process. Registration Forgot your password?
Object Oriented Approach
It is defined as set of specifications created and distributed by Object Management Group. It defines the operation performed on objects. State diagrams, which show how the system reacts to internal and external events. To make this website work, we log user data and share it with processors.
My presentations Profile Feedback Log out. Static models show the structural characteristics of a system, describe its system structure, and emphasize on the parts that make up the system.
It also includes identifying the classes and their relationships to the other classes in the problem domain, that make up an application. Use case diagrams and Class diagram.
Objectives Explain the purpose and various phases of the traditional systems development life cycle SDLC Explain when to use an adaptive approach to. Also ssadd as the spiral lifecycle model or spiral developmentit is a systems development method SDM used in information technology IT.

If you wish to download it, please recommend it to your friends in any social system. Similar terms include software life cycle and software process.
It is suitable for most business applications, game development projects, which are expected to customize or extended. In this approach, projects can be difficult to manage due to uncertain transitions between phase. This model represents the user needs bettween user view of system.
UML diagrams that represent static model include class diagram, object diagram, and use case diagram. Focus on Objects rather than data or process Covered in previous course. These models are useful in a wide variety of disciplines in the physical, biological and social sciences.
Chapter 8 Slide 1 System models September 29, The analysis should continue, in consideration of the target context, with: Class diagrams, which show the object classes in the system and the associations between these classes. Defining the problem 2. Sharif University of Technology Session 3. An Overview of Software Development 1. This approach is old and anr not preferred. It is simply the combination of process and data into a single entity.
This phase also identifies and defines the additional classes or objects that support implementation of the requirement. It performs well in situation where systems are undergoing continuous design, adaption, and maintenance. For example, diffrrence are many specific software development processes that ‘fit’ diffrrence spiral lifecycle model. A software xifference process is a structure imposed on the development of a software product. A prototype typically simulates only a few aspects of the features of the eventual program, dicference may be completely different from the eventual implementation.
Chapter 7 Slide 1 System models l Dicference descriptions of systems whose requirements are being. Share buttons are a little bit lower. Use case diagrams, which show the interactions between a system and its environment.
The objects and actors involved are listed along the top of the diagram, with a dotted line drawn vertically from these. A mixed model is a statistical model containing both fixed effects and random effects, that is mixed effects. Share buttons are a little bit lower.

System Analysis and Design Object Oriented Approach
The objective of this phase is to design and refine the classes, attributes, methods, and structures that are identified during the analysis phase, user interface, and data access. Dynamic models show the behavioral characteristics of a system, i.
Chapter 14 Slide 1 Object-oriented Design. It is suitable for real time system, embedded system and projects where objects are not the most useful level of abstraction.
