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.

Interview
A structured conversation where one participant asks questions and the other provides answers of those questions.
Software Design
Software design is the process of planning and structuring a software system’s architecture, components, interfaces, and data flow to meet functional and non-functional requirements. It ensures scalability, maintainability and performance. Key approaches include modular design, object-oriented design and architectural patterns like MVC and microservices for efficient, reliable software development.
Language-Concepts
This tag is used to understand a basic part of the language.
Challange
A challenge is a task, problem or situation that tests a person’s skills, knowledge or determination. Challenges encourage growth by pushing individuals beyond their comfort zones and inspiring creative problem-solving. In learning, technology and work environments, challenges help improve abilities, build confidence and lead to meaningful achievements through consistent effort and resilience.
max
Max refers to the maximum value in a set of numbers or elements. In programming and mathematics, the max function identifies the largest value among inputs, such as max(a, b) or max(array). It is widely used in algorithms, data analysis, comparisons and decision-making processes to determine optimal or highest results efficiently.
Query
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
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.
Database
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.
Git
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.
min
Min refers to the minimum value in a given set of numbers or elements. In programming and mathematics, the min function identifies the smallest value among inputs, such as min(a, b) or min(array). It is commonly used in comparisons, optimization problems, data analysis and algorithms to determine the lowest or least outcome efficiently.
