I Think My Paper is come From This 

Attachments:

By Mohsin Khokhar

17 McQs contains Past Papers.

1 As Per Code methodology, bin, cabinet folder locker, safe, shelf etc under which category? (Mark 2)

2 For an item which attributes can be written? (Mark 2)

3 Suppose you are designing object Model for ABC company. which techniques will use to Identify the object and the classes? (Mark 3)

4 Architectural design process consists of three activities. List them. (Mark 3)

5 A software engineer is working an online banking system. There are two scenarios for which he wants to make interaction diagrams; sequence and collaboration. Can you tell which diagram(s) is/are suitable for following scenarios and why? (Mark 5)

6 Apply Petor Coad methodology on Virtual University of Pakistan and identify actors, places, transactions and tangible things. (Mark 5)

My today paper is very simple 5 MCQS from past and 15 mcqs are conceptual

Q: Name to two type of structure (2 marks)

Q: Define UML methodology its Helpful True or False if true give the reason? (2 marks)

Q: How Encapsulation helpful in software engineering? (3 marks)

Answer: Encapsulation hides the details of the implementation of an object. Intelligent encapsulation focus design decisions that are likely to change. The ability to change the representation of an object without disturbing any of its clients is the essential benefit of encapsulation.

Q: In OO system it’s is possible to increase cohesion and decrease coupling (5 marks)

 

 Sorry Our Yad nhe Pleas share You Current Papers 

 

in k ans b bata dain ?

1:Name to two type of structure?

ans:

     Generalization-Specialization (Gen-Spec) and whole-part.

2:For an item which attributes can be written?

ans:

     The criteria for the inclusion of an attribute is that it should be included if the

system needs to know its value and it cannot get it any  other way. Don not add an

attribute for an association or aggregation. Examples of attributes are: number, name,

address, date, time, operational state, phone, status, threshold, type, etc.

3:Architectural design process consists of three activities. List them.

ans:

   System structuring

    Control modelling

     Modular decomposition

AOA!

Please everyone requested to upload their attended papers,which may be helpful for someone.

my today paper was tough 3 or 4 mcq,s from past paper

subjective bi almost new thi

1st question uml ki use case sequence case or class diagram ko modified karna tha static or dyamic mein

2nd q mein parameter name thay

3rd mein ek condition thi jis mein student pass one smaeter and apply for next samester course us pe sequence diagram bnani thi

moduletiy dive and conqure pe tha question

UML provides two different mechanisms to document the dynamic behaviour of the

system. These are sequence diagrams which provide a time-based view and

Collaboration Diagrams which provide an organization-based view of the system’s

dynamics.

The objects are organized in a horizontal line and the events in a vertical

time line.

complexity of the system we need to apply the principles of separation of concern,

modularity, and abstraction. This leads to designs that are easy to understand and hence

easy to maintain.

Separation of concern, modularity, and abstraction are different but related principles.

Separation of concern allows us to deal with different individual aspects of a problem by

considering these aspects in isolation and independent of each other.

A complex system may be divided into smaller pieces of lesser complexity called

Modules

A maintainable design is the one in which cost of system change is minimal

and is flexible enough so that it can be easily adapted to modify exiting functionality and

add new functionality

Coupling is a measure of independence of a module or component. Loose coupling

means that different system components have loose or less reliance upon each other.

Hence, changes in one component would have a limited affect on other components.

Coupling and cohesion are contrasting concepts but are indirectly related to each other.

Cohesion is an internal property of a module whereas coupling is its relationship with

other modules. Cohesion describes the intra-component linkages while couple shows the

inter-component linkages. Coupling measures the interdependence of two modules while

cohesion measures the independence of a module. If modules are more independent, they

will be less dependent upon others. Therefore, a highly cohesive system also implies less

coupling.

Modules with high cohesion and low coupling can be treated and analyzed as black

Boxes

The modules that interact with each other through message passing have low coupling

while those who interact with each other through variables that maintain information

about the state have high coupling.

6.4 Abstraction and Encapsulation

Abstractions is a technique in which we construct a model of an entity based upon its

essential characteristics and ignore the inessential details. The principle of abstraction

also helps us in handling the inherent complexity

Hiding

the internal details is called encapsulation.

Function Oriented versus Object Oriented Design

In the case of action-oriented approach, data is decomposed according to functionality

requirements. That is, decomposition revolves around function. In the OO approach,

decomposition of a problem revolves around data. Action-oriented paradigm focuses only

on the functionality of a system and typically ignores the data until it is required. Objectoriented

paradigm focuses both on the functionality and the data at the same time. The

basic difference between these two is decentralized control mechanism versus centralized

control mechanism respectively. Decentralization gives OO the ability to handle essential

complexity better than action-oriented approach.

:Name to two type of structure?

ans:

     Generalization-Specialization (Gen-Spec) and whole-part.

2:For an item which attributes can be written?

ans:

     The criteria for the inclusion of an attribute is that it should be included if the

system needs to know its value and it cannot get it any  other way. Don not add an

attribute for an association or aggregation. Examples of attributes are: number, name,

address, date, time, operational state, phone, status, threshold, type, etc.

3:Architectural design process consists of three activities. List them.

ans:

   System structuring

    Control modelling

     Modular decomposition

 

Some of the key advantages which make the object-oriented technology significantly
attractive than other technologies include:
 Clarity and understandability of the system, as object-oriented approach is closer to
the working of human cognition.
 Reusability of code resulting from low inter-dependence among objects, and
provision of generalization and specialization through inheritance.
 Reduced effort in maintenance and enhancement, resulting from inheritance,
encapsulation, low coupling, and high cohesion.

A message is
some action that one object performs upon another in order to elicit a reaction. The
operations that clients may perform upon an object are called methods.
The structure and behavior of similar objects are defined in their common class.
