What are the main parameters you consider when selecting a database management system for a project?

When choosing a database management system (DBMS) for a project, I usually consider the following parameters:

• Data type and structure: relational (SQL) or non-relational (NoSQL) data, the need for supporting complex relationships or flexible schema.

• Scalability: horizontal or vertical scalability, support for clusters and replication.

• Performance: read/write speed, latency, indexing requirements.

• Reliability and fault tolerance: support for transactions, backup, recovery.

• Compatibility and integration: support for required programming languages, drivers, ORM.

• Community and support: availability of documentation, community activity, commercial support.

• License and cost: open source or commercial, licensing and support costs.

• Project features: security requirements, compliance with standards, specific functions (e.g., full-text search, geospatial data).

Considering these parameters, the most suitable DBMS is chosen for specific tasks and project conditions.
