What type of database management system do you use for moderate data volumes and loads?

For moderate data volumes and loads, relational database management systems (RDBMS) such as PostgreSQL, MySQL, or MariaDB are typically used. They provide:

• Structured data storage with schema support.
• Reliability and data integrity through transactions and constraints.
• Good performance under moderate loads.
• Wide support and tools for work.

For example, a web application with hundreds of thousands of records and moderate read/write load would be an optimal choice for a relational RDBMS. If the load or data volumes increase significantly, NoSQL solutions or scaling can be considered.
