Monolithic Database

A monolithic database is a traditional database architecture where all data is stored in a single, centralized database system. It typically uses a single database management system (DBMS) to handle all data storage, processing, and management functions for an application. This approach contrasts with distributed or microservices-based database architectures.

Also known as: Centralized Database, Single Database, Traditional Database, Unified Database, Monolith DB

Why learn Monolithic Database?

Developers should use monolithic databases for simpler applications with straightforward data requirements, where data consistency and ACID transactions are critical, such as in financial systems or small-scale enterprise applications. They are also suitable when development teams are small, as they reduce operational complexity compared to distributed systems.
