Question: what course should i concentrate on to become a computer expert or DBA? 

Answer: the term computer expert can mean a lot of different jobs.\n\na dba - database administrator - is just one kind of computer expert. a pretty boring kind too, if you ask me.\n\nYou could also be a programmer or a software engeneer or do something less technical, but still in the field of computers.\n\nI'm an information analyst/ project manager/ applications manager. To me, these are more interesting jobs than a dba because you work more closely with other people.
