How to find database projects?

There are several freelancing platforms available that would help you in getting your first database project. You can start with Upwork, Fiverr, or Freelancer. Fiverr and Upwork are my personal favorite although it is difficult to get your first project on Upwork.

I would suggest starting with Fiverr or Freelancer.

Remember, an organization will always prefer someone with a graduate degree for a database administrator. Without a university degree, the chances of climbing up in the organization are extremely low.

Which Database is easy to learn for beginners?

There are several database management systems out there. I would recommend starting with either MS Access or MySQL. Both of these are easy to learn and you do not need to buy any expensive suite of software for them. If you already have Office suite, then you would probably have access to MS Access as well. If you do not, get started with MySQL. It’s freely available.
