Relational database

The industry standard for structured data management using SQL and ACID-compliant tables.

Relational databases (RDBMS) organize information into predefined tables linked by unique keys (IDs). This architecture ensures data integrity through ACID properties: Atomicity, Consistency, Isolation, and Durability. Since E.F. Codd proposed the model at IBM in 1970, it has become the backbone of global finance and logistics. Systems like PostgreSQL and MySQL handle millions of transactions per second by enforcing strict schemas and using SQL for complex joins. It is the go-to choice when data accuracy is non-negotiable.
