Popular database models and management systems include:
- Relational database management system (RDBMS) -- adaptable to most use cases, but RDBMS Tier-1 products can be quite expensive.
- NoSQL DBMS -- well-suited for loosely defined data structures that may evolve over time.
- In-memory database management system (IMDBMS) -- provides faster response times and better performance.
- Columnar database management system (CDBMS) -- well-suited for data warehouses that have a large number of similar data items.
- Cloud-based database management system -- the cloud service provider is responsible for providing and maintaining the DBMS.
