Database

For some now I have been thinking what to do to develop my own database. I was not sure if I was up to the task. Part of me was saying that I was, while part of me was saying to give up. I knew something about database development from my own experience, but I was unsure whether it was enough to make sure that I am going to know how to develop a database. Were you given a chance to develop your own database, would you be willing to do it on your own or would you ask somebody for help? To be honest, I do not know what I would do.
