In which SQL databases have you had hands‑on experience?
💡 Model Answer
I have worked extensively with several relational database systems. In my recent role, I used MySQL for web application back‑ends, writing complex SELECT queries, stored procedures, and optimizing indexes. I also have experience with PostgreSQL, where I leveraged its advanced features such as window functions, common table expressions, and JSONB support for semi‑structured data. Additionally, I have used Microsoft SQL Server in an enterprise environment, creating ETL jobs with SSIS and writing T‑SQL scripts for data migration. I am comfortable with database design, normalization, and performance tuning across these platforms, and I can adapt quickly to new SQL dialects as needed.
