## Basic Concepts
Databases are ubiquitous, but no single database model can cater to the diverse needs of various projects and servers. There's a spectrum of database types and database management systems.

- **Database (DB)** is a repository of information.

- **Database Management System (DBMS)** offers a suite of tools to manage and interact with a database. It allows users to oversee the data, structure the database, and provides an interface for these operations.

Primarily, there are two database models: **relational** and **non-relational**. Additionally, there are multi-model database management systems, such as **Oracle Database**.

**Non-relational databases** encompass a variety of types, including document data stores, column-oriented databases, key-value stores, and graph databases.
