, , , ,

Object Oriented Design (OOD) is one approach of software design and is defined as the

process of planning a system of interacting objects for the purpose of solving a software problem

.

What are the 4 key activities in an object oriented design process?

Terms in this set (37) The four basic activities in software development are requirements analysis (deciding what the program should do)

, design (deciding how to do it)

, implementation (writing the solution in source code), and testing (validating the implementation).

What are the steps involved in Object Oriented Design?

  • Object Identification. The first step of object design is object identification. …
  • Object Representation. …
  • Classification of Operations. …
  • Algorithm Design. …
  • Design of Relationships. …
  • Implementation of Control. …
  • Addition of Redundant Associations. …
  • Omission of Non-Usable Associations.

Why is it important to specify the interfaces of components that are being developed by a software engineering team?

Why is it important to specify the interfaces of components that are being developed by a software engineering team? …

You need to specify interfaces so that objects and subsystems can be designed in parallel.

What are the activities of object oriented design?

Object Oriented Design (OOD) is one approach of software design and is defined as the

process of planning a system of interacting objects for the purpose of solving a software problem

.

What are the key concepts of object oriented design?

Object-oriented programming has four basic concepts:

encapsulation, abstraction, inheritance and polymorphism

. Even if these concepts seem incredibly complex, understanding the general framework of how they work will help you understand the basics of a computer program.

What is the difference between structured design and object oriented design?

The main difference between structured and object oriented programming is that

structured programming allows developing a program using a set of modules or functions

, while object oriented programming allows constructing a program using a set of objects and their interactions.

How do design patterns reuse?

How do design patterns contribute to reuse?

abstraction level concept reuse

– Using patterns means that you reuse the ideas but can adapt the implementation to suit the system that you are developing.

What is object-oriented development lifecycle?

The object-oriented life cycle model considers

‘objects’ as the basis of the software engineering process

. The development team starts by observing and analyzing the system they intend to develop before defining the requirements. Once the process is over, they focus on identifying the objects of the system.

What is the basic activity in designing an application in Ooad?

Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by

applying object-oriented programming

, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.

What is system design and its types?

Definition: Systems design is

the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements

. … The designs can be defined in graphical or textual modelling languages.

How do you identify objects in object-oriented programming?

  1. Start with a scenario (usually representing a normal course through a use case)
  2. Identify initial classes/objects and make cards for them (this is can often be done by picking out the nouns)
  3. Going through a scenario helps identify responsibilities of a chosen object.

What is the process of system design?

There are four system design processes:

developing stakeholder expectations, technical requirements, logical decompositions, and design solutions

. … If the answer to any of these questions is no, then changes to the design or stakeholder expectations will be required, and the process starts again.

WHY IS interfaces so important?

Identifying interfaces

helps you to define your system’s boundaries

. Identifying interfaces also helps you understand the dependencies your system has with other systems and dependencies other systems have with your system.

What are the levels at which software reuse is possible?

What are the 4 levels at which software reuse is possible? ~

The abstraction level where knowledge of successful abstractions is reused

. ~The object level where objects classes and methods from libraries are reused. ~The component level where collections of objects are reused.

Why are interfaces needed?

Why do we use interface ?

It is used to achieve total abstraction

. Since java does not support multiple inheritance in case of class, but by using interface it can achieve multiple inheritance . … The reason is, abstract classes may contain non-final variables, whereas variables in interface are final, public and static.
