Monolithic Databases
Monolithic databases are centralized, single-tier database systems where all data is stored and managed in a single, unified database instance. They typically use a traditional relational database management system (RDBMS) like MySQL or PostgreSQL, handling all data storage, processing, and transactions in one place. This architecture contrasts with distributed or microservices-based database approaches, offering simplicity in deployment and management but potential scalability limitations.
Developers should use monolithic databases for applications with straightforward data models, moderate traffic, and where ACID compliance and strong consistency are critical, such as in financial systems or small-to-medium business applications. They are ideal when rapid development and low operational complexity are priorities, as they avoid the overhead of distributed data management. However, they may not suit high-scale, globally distributed systems requiring horizontal scalability.
