What are the main properties and parameters that can be highlighted in database management systems?

Main properties and parameters of database management systems (DBMS) include:

• Data types: support for various data types (numbers, strings, dates, etc.).
• Data model: relational, document, graph, etc.
• Transactions: support for atomic operations with ACID properties (atomicity, consistency, isolation, durability).
• Query language: for example, SQL for relational DBMS.
• Scalability: ability for horizontal or vertical scaling.
• Security: authentication, authorization, data encryption.
• Backup and recovery: mechanisms to protect data.
• Performance: indexes, caching, query optimization.

For example, when working with PostgreSQL, it is important to consider transaction support and advanced data types, while with MongoDB, schema flexibility and scalability are key.
