What is component based design?

What is a component-based design? The concept of component-based design envisions building websites out of ready-made elements (components), which are designed and programmed segments to be used as building blocks for your website. What is more, thanks to their modular nature, they can be easily reused on all subpages.

What is the difference between system design and object design?

System design is the designing the software/application as a whole [high level] that may include analysis, modelling, architecture, Components, Infrastructure etc. whereas the objected-oriented design is the set of defined rules/concepts to implement the functionalities within a software.

What are the difference between components and classes?

Answer: Class is a datatype that encloses data and function members. Component is a particular class that must implement the IComponent interface . It is the base class for all components in the common language runtime that marshal by reference.

What is difference between component and directive?

Component is used to break up the application into smaller components. But Directive is used to design re-usable components, which is more behavior-oriented. That is why components are widely used in later versions of Angular to make things easy and build a total component-based model.

What’s the difference between a component-based architecture and a service oriented architecture?

If you threatened to stick a rusty fork in my eye and forced me to generalise, I’d say that component-based development was a technique for modelling and assembling a specific piece of software, where as SOA is a technique for organising separate systems so they can talk to each other.

What are the advantages of component-based development?

Advantages. Ease of deployment − As new compatible versions become available, it is easier to replace existing versions with no impact on the other components or the system as a whole. Reduced cost − The use of third-party components allows you to spread the cost of development and maintenance.

What are the differences between an object and a process model?

In object models, behaviour is split across object types, whereas in process models, behaviour is captured along chains of logically related tasks. Also, object models and process models lend themselves to different styles of implementation.

What is the difference between component and deployment diagram explain with example?

Simply put, a Component diagram shows you how different elements of your system have been grouped together (into assemblies / dlls etc) – and the link between these components. A Deployment diagram takes you one step further and describes on which hardware elements do these components reside.

What is the difference between component diagram and class diagram?

A component diagram has a higher level of abstraction than a Class Diagram – usually a component is implemented by one or more classes (or objects) at runtime. Components are similar in practice to package diagrams, as they define boundaries and are used to group elements into logical structures.

What is object-oriented design?

Object oriented design is the result of focusing attention not on the function performed by the program, but instead on the data that are to be manipulated by the program. Thus, it is orthogonal to function -oriented design. Object-oriented design begins with an examination of the real world “things”.

What is the difference between object-oriented and component-oriented programming?

In a nutshell, object-oriented programming focuses on the relationships between classes that are combined into one large binary executable, while component-oriented programming focuses on interchangeable code modules that work independently and don’t require you to be familiar with their inner workings to use them.

What is the difference between a component and an object?

A component can be implemented in any programming language unlike a object. An object can be implemented only in Object oriented programming language. 7. A component have persistence. An object does not have persistence.

What is the difference between function oriented design and stepwise refinement?

Function oriented design is the result of focusing attention to the function of the program. This is based on the stepwise refinement. Stepwise refinement is based on the iterative procedural decomposition. Stepwise refinement is a top-down strategy where a program is refined as a hierarchy of increasing levels of details.
