Stack

A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. Elements are added (push) and removed (pop) from the top, making it ideal for tasks like expression evaluation, backtracking and function call management. Common implementations include arrays and linked lists for efficient data handling.

Array
An array is a linear data structure that stores multiple elements of the same type in contiguous memory locations. It allows fast access using index positions, making operations like retrieval efficient. Arrays are widely used for organizing data, implementing algorithms and building other data structures. However, their size is fixed, making resizing difficult compared to dynamic collections.
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.
