DBMS is a software system that manages databases. In case of overload, optimize queries, add indexes, or scale up hardware.

• DBMS stands for Database Management System

• It is a software system that manages databases

• In case of overload, optimize queries to reduce load on the database

• Add indexes to improve query performance

• Scale up hardware by adding more memory, CPU, or storage

• Use load balancing to distribute the load across multiple servers

Entity Framework is an ORM tool used to map database tables to classes in .NET applications.

• Entity Framework simplifies database access by allowing developers to work with objects instead of SQL statements.

• It supports various database providers such as SQL Server, MySQL, and Oracle.

• It provides features like LINQ to Entities, automatic change tracking, and database migrations.

• Example: In my last project, I used Entity Framework to build a web application that allowed users to ...read more

Static and final keywords are used in Java to define class-level variables and constants respectively.

• Static keyword is used to define class-level variables and methods, which are shared among all instances of the class.

• Final keyword is used to define constants that cannot be changed once initialized.

• Static variables are accessed using the class name, while final variables are accessed using object references.

• Example: 'static int count;' defines a static variable 'count', whi...read more

Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

• Abstract class can have constructors, fields, and methods, while interface cannot have any of these.

• A class can implement multiple interfaces but can only inherit from one abstract class.

• Abstract classes are used to provide a common base for multiple classes, while interfaces define a contract that implementing classes must follow.

Aggregation is a concept in object-oriented programming where one object is composed of multiple objects.

• Aggregation is a form of association where one class contains references to other classes.

• It represents a 'has-a' relationship between objects.

• For example, a car has an engine, wheels, and seats.

• Stacks are data structures that follow the Last-In-First-Out (LIFO) principle.

• They are used to store and retrieve data in a specific order.

• An example of a stack is the call stack i...read more

Cloud computing is the delivery of computing services over the internet.

• Cloud computing allows users to access data and applications from anywhere with an internet connection.

• It eliminates the need for physical servers and hardware, reducing costs and increasing scalability.

• Examples of cloud computing services include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

Count set bit in a given number

• Use bitwise AND operator with 1 to check if the rightmost bit is set

• Shift the number to the right by 1 bit after each iteration

• Repeat until the number becomes 0

• Add 1 to the count for each set bit

SDLC stands for Software Development Life Cycle.

• It is a process used to design, develop, test, and deploy software.

• It consists of several phases such as planning, analysis, design, implementation, testing, and maintenance.

• It helps to ensure that the software is developed efficiently, on time, and within budget.

• Examples of SDLC models include Waterfall, Agile, and DevOps.

Multi threading is a technique to execute multiple threads concurrently, improving performance and responsiveness.

• Threads are lightweight processes that share the same memory space.

• They can be created using classes like Thread or by implementing the Runnable interface.

• Thread synchronization is important to avoid race conditions and ensure data integrity.

• Common multi-threading concepts include thread pools, locks, semaphores, and barriers.

• Examples of multi-threading applicatio...read more
