OOPs concepts are the fundamental principles of object-oriented programming, including inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex i...read more

SOLID principles are a set of five design principles that help make software designs more understandable, flexible, and maintainable.

• S - Single Responsibility Principle: A class should have only one reason to change.

• O - Open/Closed Principle: Software entities should be open for extension but closed for modification.

• L - Liskov Substitution Principle: Objects of a superclass should be replaceable with objects of its sub...read more

Repartitioning involves changing the number of partitions in a dataset, while coalesce involves reducing the number of partitions without shuffling data.

• Repartitioning increases or decreases the number of partitions in a dataset, which may involve shuffling data across the cluster.

• Coalesce reduces the number of partitions in a dataset without shuffling data, which can improve performance by minimizing data movement.

• Exa...read more

Dataframe is a distributed collection of data organized into named columns, while RDD is a distributed collection of data organized into partitions.

• Dataframe is higher level abstraction than RDD in Spark.

• Dataframe is immutable and supports SQL queries, while RDD is mutable and does not support SQL queries.

• Dataframe provides optimization through Catalyst optimizer, while RDD does not have built-in optimization.

• Example: ...read more

Stored procedures are precompiled SQL queries stored in a database for reuse.

• Stored procedures are used to encapsulate logic for data manipulation in a database.

• They can accept input parameters and return results.

• Stored procedures can improve performance by reducing network traffic and optimizing query execution.

• Examples include procedures for inserting, updating, or deleting records in a database.

Clean code is well-structured, readable, and maintainable code that follows best practices and standards.

• Clean code is easy to read and understand by others.

• It follows consistent naming conventions for variables, functions, and classes.

• Clean code is modular, with each function or class having a single responsibility.

• It minimizes duplication and follows the DRY (Don't Repeat Yourself) principle.

• Clean code is well-tested

Some new features in .NET Core include cross-platform support, performance improvements, and modular design.

• Cross-platform support allows developers to build and run applications on Windows, macOS, and Linux.

• Performance improvements such as faster startup times and lower memory usage.

• Modular design with smaller runtime packages for more efficient deployment.

• Support for C# 8.0 features like nullable reference types and
