Frequently asked questions

What is the difference between SQL and NoSQL databases?

SQL databases (relational) use structured schemas with tables and enforce ACID properties, suited for transactional data. NoSQL databases (document, key-value, etc.) offer flexible schemas, horizontal scalability, and eventual consistency, ideal for unstructured data and high throughput applications.

Which database should we choose for a new web application?

For most web applications, PostgreSQL or MySQL offer excellent balance of features and simplicity. MongoDB suits applications with flexible data models. For cloud-first projects, consider managed services like Amazon RDS to eliminate infrastructure management overhead.

How important is licensing cost when selecting a database?

Licensing costs vary dramatically. Open-source options like PostgreSQL and MySQL are free, whilst Oracle and SQL Server require significant per-core or per-instance licensing. Evaluate total cost of ownership including infrastructure, support, and operational overhead alongside licensing fees.
