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.
