NICE Component Based Technology Question Paper

Unit-I :
Two Mark Questions :
1. Define software component :
A software component is a system element offering a predefined serviceable to communicate with other components.

2. Specify the characteristics of object :
Object is a unit of instantiation, it has a unique identity. It may have state and this can be externally observable.

3. What is prototype object? :
The object may be implicitly available in the form of an object that already exists. Such a preexisting object is called a prototype object.

4. What is factory object and methods? :
Factory objects : It can be an object of its own. Factory methods: Methods on objects that return freshly created other objects are another variation.

5. What are modules? :
Modules do not have a concept of instantiation whereas classes do. Modules can be used and always and have been used to package multiple entities.

6. Specify the non-technical aspects that are need in interfaces :
** A component have multiple interfaces, each representing a service that the component offers.
** Redundant introductions of similar interfaces need to be minimized.
** Requires a small number of widely accepted unique naming schemes.

7. Define callback :
Callbacks are a common feature in procedural libraries that has to handle asynchronous events.

8. What is component architecture? :
Component architecture is the pivotal basis of any large-scale software technology and is of utmost importance for component based systems.

9. Specify some cornerstones of a component architecture :
** Interaction between components and their environment is regulated.
** The roles of components are defined.
** Tool interfaces are standardized.

10. Specify the roles of an architecture :
** Architecture needs to create simultaneously the basis for independence and cooperation.
** An Architecture defines overall invariants.
** It needs to be based on the principal considerations of overall functionality
** It prescribes proper frameworks for all involved mechanisms.

11. What is the use of conceptual level? :
A component framework is a dedicated and focused architecture usually around a few key mechanisms and a fixed set of policies for mechanisms at the component level.

12. Define component framework :
A component framework is a dedicated and focused architecture usually around a few key mechanisms and a fixed set of policies for mechanisms at the component level.

13. What is a resource? :
A resource is a frozen collection of typed items.

14. Define middleware :
Middleware is a name for the set of software that sits between various operating systems and a higher distributed programming platform.

15. Categorize the middleware :
** Message oriented middleware(MOM).
** Object oriented middleware(OOM).

16. What is generative programming? :
Generative programming aims at transformations approach to the construction of software.

17. Specify the areas used in generative approaches :
** Used to produce individual components.
** Used to enhance composed systems.

18. Specify the criteria that is used to fulfill the software definition :
** Multiple use
** Non-context specific.
** Composable with other component.
** Encapsulated.

19. Specify the fundamental properties of component technology :
** If a component fails to function it must not violate system-wide rules.
** Software development processes that do not depending on testing
** Performance of a component system is affected in non-trivial ways by the actual composition

20. What is enhance composed systems and give example :
They need to be positioned in such a way that they do not interfere with the unit of deployment characteristic of components.

Eg :JIT technique.
