What parameters do you consider when choosing a database for a project?

When choosing a database for a project, I consider the following parameters:

• Type of data and structure: relational (SQL) databases are suitable for structured data with clear relationships, NoSQL is for flexible schemas or unstructured data.
• Volume and scalability: how large the data volume is and how quickly it will grow; whether horizontal scalability is needed.
• Performance requirements: read/write speed, latency.
• Transactional consistency: whether strict ACID compliance is required or if eventual consistency is acceptable.
• Project features: e.g., support for geospatial data, full-text search, analytics.
• Ecosystem and support: availability of drivers for Go, community, documentation.
• Ease of administration and deployment: requirements for support, backup.

Example: for a project with financial transactions, I would choose PostgreSQL for its reliability and transactional support. For a project with a large volume of logs, NoSQL options like MongoDB or Cassandra are suitable.
