Perguntas frequentes
1. Which Database Management Systems (DBMS) do you support?
We work with all major relational database management systems, including MySQL, PostgreSQL, Microsoft SQL Server (T-SQL), Oracle, SQLite, and MariaDB. I can also assist with cloud database platforms like Google BigQuery or Amazon Redshift.
2. What information do you need to get started on my project?
To get started, please provide: The database system you are using (e.g., MySQL, PostgreSQL). Your database schema or table structures (DDL/SQL scripts or screenshots of the schema). Sample data or mock data (if applicable). A clear description of the expected output or desired query logic.
3. Will my database and confidential data remain secure?
Yes, absolutely! Your data privacy and security are top priorities. We recommend sharing sample/mock data or anonymized data whenever possible. If access to your live environment is required, we strictly handle all credentials with confidentiality.
