What Type Of Projects Does A Database Administrator Work On?

I need to make a project on dba.so I  need some matter to that.

A Database Administrator can work on any project that involves the implementation and maintenance of a database environment. The environment can range from banks to hospital to schools and universities to airports. Regardless of the project, the role of a DBA involves designing, implementing and maintaining the database system. It develops policies and procedures for data security and the use of the database management system, In addition to this, staff training on the database management and use is also part of a Dba job.
