Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/wittyicon29/in-memory-db

An in-memory database using C++ is a system that stores data primarily in RAM for fast access and manipulation. It supports basic CRUD operations and may include features for concurrency control and optional data persistence.
