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.
This tag is used to understand a basic part of the language.
Application design is the process of planning and structuring an application’s architecture, user interface, data flow and functionality to meet user and business requirements. It involves decisions on technology stack, design patterns, scalability and security. Good application design ensures performance, maintainability and a seamless user experience across platforms and devices.
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.
SQL stands for Structured query language. It is a programming language for storing and processing information in a relational database. It is standard language for accessing and manipulating databases.
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.
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.
A git commit is a command used to save changes to the local repository, creating a snapshot of the project at a specific point in time. Each commit includes a unique ID, message and details of modified files. Commits help track progress, document work and enable reverting or reviewing changes, forming the foundation of version control in Git.
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.
The two-pointer technique is an efficient algorithmic approach that uses two indexes to traverse data structures like arrays or strings. The pointers move toward each other, away from each other or in the same direction to solve problems involving searching, pair finding or window management. It reduces complexity, often turning O(n²) solutions into O(n), making it ideal for optimized problem-solving.
