System Design
System design is the process of defining the architecture, components, modules, interfaces and data flow of a system to meet specific requirements. It focuses on creating scalable, efficient and maintainable solutions, covering both high-level design (HLD) and low-level design (LLD). Essential for building reliable, high-performance software systems.

MySQL is an open-source relational database management system widely used for storing and managing structured data. It supports SQL for querying, updating and controlling data efficiently. Known for reliability, speed and scalability, MySQL powers web applications, enterprise systems and cloud platforms. It is commonly used with PHP, Java, Python and modern application stacks like LAMP and MERN.
Java is a high-level object-oriented programming language. it's firstly released by Sun Microsystems in 1995. Use this tag when you're having queries using or understanding the language. This tag is also applicable to Java libraries and frameworks.
Git is a distributed version control system used to track changes in code, collaborate with teams and manage project history. It allows developers to work independently on branches, merge updates and revert to previous versions when needed. Git ensures code integrity, supports parallel development, and is widely used in software engineering for efficient source code management and collaboration.
A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information. Use this tag if you have questions about designing a database.

Artificial Intelligence (AI) is the simulation of human intelligence in machines, enabling them to think, learn and make decisions. It powers systems to solve problems, recognize patterns, understand language and adapt over time. AI is used in various fields, including robotics, healthcare, finance and everyday applications like virtual assistants.
In C#, Collections are classes in the System.Collections and System.Collections.Generic namespaces that store and manage groups of related objects. They include types like List<T>, Dictionary<TKey,TValue>, Queue<T> and Stack<T>. Collections offer dynamic sizing, built-in search, sorting and iteration, making data handling efficient and flexible in C# applications.
In databases, a query is a request to retrieve, insert, update or delete data. Written in SQL (Structured Query Language), queries can be simple, like fetching all rows from a table, or complex, involving joins, conditions and aggregations. They are essential for interacting with and managing database information efficiently.
DSA (Data Structures and Algorithms) is a fundamental concept in computer science that focuses on efficiently storing, organizing and processing data. Data structures like arrays, linked lists, stacks and trees manage data, while algorithms provide step-by-step solutions to problems. Mastering DSA is essential for writing optimized, scalable and high-performance code.
