Allows you to represent composite objects in the form of a hierarchy

It uses independent interfaces for representing individual and composite objects

It uses an individual object that is composed of two or more composite objects

It represents just a collection of different objects

Adapter pattern is used to access facades

The Adapter pattern adds an indirection object for low coupling

The Façade pattern hides the complexity of a subsystem from a client

None of the above

Assigns responsibility to an intermediate object

Creates a convenient class that supports high cohesion and low coupling

Creates a convenient class that supports low cohesion and high coupling

Protects the system from unexpected variations

Solutions to common problems

Guiding Principles for designing a system

General concepts of designing

None of the above

Handles the message generated when a system event or operation takes place

assigns the responsibility for creating new class instance or object

Determine how a system handles conditional variations

Creates a convenient class

Avoid direct coupling

Maintain low coupling and high reusability

None of the above

Both A and B

Is used in the process of alternative evaluation

Determine how a system handles conditional variations

Assign responsibilities to an intermediate object

Defines guiding principles for assigning responsibilities to objects

It helps achieve proper fucntionality if the tasks are ordered

it is mandatory that the sequence added to a transaction must be the best execution sequence possible

The number of tasks to be executed affects the overall performance of a transaction

None of the above

Modifying a persistent object results in the instance update of the database

Only one persistent object can refer to an instance of a class at any given time

The transactional state of an object decides the response to an operation

None of the above

The model, view and the controller objects are independent of each other and can be easily used to integrate a new client's business logic

The new client can be coded into the controller as additional business logic for the enterprise data

The MVC pattern makes provisions for any new client at the time of development of the enterprise solution

The MVC Pattern provides for many models to be used by one controller, thus making it easy to incorporate a new client
