FAQ
Frequently Asked Questions
No. The learning roadmap starts with computing and database fundamentals before progressing into SQL, design, administration and advanced engineering topics.
The academy focuses on transferable database concepts and includes learning paths around SQL, relational databases such as MySQL and PostgreSQL, cloud database concepts and broader data engineering.
The educational lab model is designed around controlled, authorized sandbox environments. Learners should only work with systems and accounts they are explicitly authorized to use.
Yes. Administration topics include users, roles, permissions, configuration concepts, monitoring, backup, recovery, maintenance and operational reliability.
No. This homepage is intentionally database-free and can be uploaded directly to standard PHP hosting. Backend database functionality can be added later as a separate authenticated system.
