Most Frequently asked Interview Questions of entity-framework(2024)

Database migrations in Entity Framework (EF) are a way of managing changes to the database schema over time in sync with the changes made in the application's data model (e.g., adding/removing fields, changing data types, etc.). Migrations allow developers to evolve the database schema in a structured and manageable way without losing data or causing inconsistency between the application's model and the actual database.

Database concurrency refers to the situation where multiple users or processes try to access and modify the same data simultaneously. In a multi-user environment, this can lead to problems such as lost updates, where one user's changes overwrite another's, or dirty reads, where data is read before it is fully committed.

Most Frequently asked entity-framework Interview Questions and Answers

Entity Framework (EF) provides a powerful and flexible way to manage changes to the database schema over time through a feature known as migrations. Migrations help you evolve your database schema as your application’s data model (C# classes) changes, ensuring that the database structure and the application code stay in sync.

Most Frequently asked entity-framework Interview Questions (2024)

Lazy loading in Entity Framework (EF) is a technique used to delay the loading of related data until it is specifically needed. It allows entities and their related navigation properties to be loaded from the database only when they are accessed for the first time, rather than being eagerly loaded along with the parent entity. This can help improve performance by reducing the amount of data retrieved initially, especially when the related data is not always required.

Entity Framework (EF) is an open-source Object-Relational Mapping (ORM) framework for .NET applications, developed by Microsoft. It allows developers to interact with databases using .NET objects rather than SQL queries, making database manipulation more intuitive and integrated within the application code.

Most Frequently asked Interview Questions of hibernate

Hibernate Query Language (HQL) is a database-independent query language used in Hibernate for querying the database. HQL is similar to SQL (Structured Query Language) but it operates on objects rather than database tables, and it is designed to work seamlessly with the object-oriented nature of Hibernate. HQL allows you to write queries that interact with Java objects (entities) rather than database tables and columns directly, which helps in maintaining a layer of abstraction between the application and the database.

Most Frequently asked hibernate Interview Questions and Answers

Hibernate Mapping refers to the process of defining the relationship between Java objects (or entities) and database tables in Hibernate. Hibernate, as an Object-Relational Mapping (ORM) framework, allows developers to map Java classes to database tables and manage the data between them seamlessly. This process involves defining how Java objects (entities) are represented in the database and vice versa, which includes relationships, primary keys, columns, and other constraints.

Most Frequently asked hibernate Interview Questions

Hibernate is an Object-Relational Mapping (ORM) framework for Java that simplifies database interactions by mapping Java objects to relational database tables. It eliminates the need for developers to write complex SQL code manually for common database operations like CRUD (Create, Read, Update, Delete). Hibernate automatically handles the conversion between Java objects and database records, making it easier to interact with relational databases in an object-oriented manner.

Most Frequently asked performance Interview Questions (2024)

Performance optimization in software development refers to the process of improving the efficiency, speed, and responsiveness of software applications. The goal is to make sure that the application performs well under different conditions, handles large datasets efficiently, responds quickly to user interactions, and scales effectively with increasing usage.
