Why shouldn't I use the Repository Pattern with Entity Framework?
- You should not use the Repository Pattern with Entity Framework as it can lead to poor performance and scalability issues.
- You should not use the Repository Pattern with Entity Framework as it is not compatible with the technology.
- You should not use the Repository Pattern with Entity Framework as it provides similar functionality and can lead to unnecessary complexity and code duplication.
- You should use the Repository Pattern with Entity Framework as it provides a way to abstract the data access layer and improve testability.
You should not use the Repository Pattern with Entity Framework as it provides similar functionality and can lead to unnecessary complexity and code duplication. Entity Framework provides an abstraction over the data access layer, making the Repository Pattern redundant.
What is the purpose of the Factory Method design pattern?
- To create objects without specifying the exact class of object that will be created.
- To define an interface for creating objects in a superclass, but allow subclasses to alter the type of objects that will be created.
- To encapsulate the creation of objects within a separate class.
- To provide a way to instantiate objects of a specified class.
The Factory Method design pattern provides a way to create objects without specifying the exact class of object that will be created. This allows for greater flexibility and modularity in the design of a system.
What is the difference between the Iterator and Composite patterns?
- None of the above
- The Iterator and Composite patterns are the same
- The Iterator pattern composes objects into tree structures to represent part-whole hierarchies, while the Composite pattern provides a way to access the elements of a collection object in a sequential manner
- The Iterator pattern provides a way to access the elements of a collection object in a sequential manner, while the Composite pattern composes objects into tree structures to represent part-whole hierarchies
The Iterator pattern provides a way to access the elements of a collection object in a sequential manner, while the Composite pattern composes objects into tree structures to represent part-whole hierarchies
Is Unit Of Work equals Transaction? Or it is more than that?
- It is equal to a Transaction
- It is less than a Transaction
- It is more than a Transaction
- It is not related to a Transaction
Unit of Work is more than a Transaction, as it encompasses multiple database operations into a single unit of work, including operations such as inserting, updating, and deleting records, as well as managing transactions and detecting conflicts. Transactions are used to ensure that either all or none of the operations succeed.
What are the entities of the Intercepting Filter pattern?
- Factory, Product, Concrete Product, Creator
- Filter, Filter Chain, Target, Filter Manager
- Observer, Subject, Client, Concrete Observer
- Singleton, Thread Safe Singleton, Lazy Initialization
The entities of the Intercepting Filter pattern are: Filter, Filter Chain, Target, and Filter Manager. The Filter performs the pre-processing on the request, the Filter Chain holds a list of filters and passes the request to each one, the Target is the resource that handles the request, and the Filter Manager manages the filters and decides which filter to use.
What is State pattern?
- A behavioral design pattern that allows an object to alter its behavior when its internal state changes. The object appears to change its class, but the change is implemented as a state transition within the same object. This allows for a cleaner, more maintainable implementation of state-dependent behavior.
- A creational design pattern that is used to create objects from a common interface or base class, but with different underlying implementations depending on the specific context.
- A design pattern that focuses on managing the flow of control within an application, with the goal of improving modularity and maintainability.
- A structural design pattern that uses inheritance to compose complex objects from simple objects, with the goal of reducing coupling and increasing cohesion between the objects.
The State pattern is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The change in behavior is implemented as a state transition within the same object, rather than as a change in class. This results in a cleaner, more maintainable implementation of state-dependent behavior.
What is the difference between the Flyweight and Singleton patterns?
- None of the above
- The Flyweight and Singleton patterns are the same
- The Flyweight pattern conserves memory by sharing common data among objects, while the Singleton pattern ensures that only one instance of a class exists in the system
- The Flyweight pattern ensures that only one instance of a class exists in the system, while the Flyweight pattern conserves memory by sharing common data among objects
The Flyweight pattern conserves memory by sharing common data among objects, while the Singleton pattern ensures that only one instance of a class exists in the system
What are the entities of Service Locator pattern?
- Cache, Client, Service, Service Locator, and InitialContext
- Client, Service Locator, Service, InitialContext, and Cache
- InitialContext, Cache, Client, Service Locator, and Service
- Service, InitialContext, Service Locator, Cache, and Client
The entities of the Service Locator pattern are: Service, InitialContext, Service Locator, Cache, and Client. The Service represents the service being located. The InitialContext is responsible for performing the actual lookup of the service. The Service Locator acts as a cache, keeping track of services that have already been looked up. The Cache stores references to services that have already been looked up. The Client is the entity that requires access to the service.
What is the purpose of the Interpreter pattern?
- To create complex objects step by step, using a builder object to abstract the process of creating the object
- To define a grammatical representation for a language and provide an interpreter to deal with this grammar
- To provide a common interface for a group of related classes
- To provide a way to pass requests along a dynamic chain of receivers until one of them handles the request
The Interpreter pattern defines a grammatical representation for a language and provides an interpreter to deal with this grammar
What is an Aggregate Root in the context of Repository Pattern?
- A boundary object around a group of objects, that ensures the consistency of the data
- A special type of object that implements data access logic
- An object that is the only object that should be accessed directly, while all other objects are accessed through it
- An object that is the parent of all other objects in the aggregate and controls the consistency of all objects in the aggregate
An Aggregate Root in the context of Repository Pattern is a boundary object around a group of objects, which ensures the consistency of the data. It is the parent of all other objects in the aggregate and controls the consistency of all objects in the aggregate.
