Well, my advice for someone starting their professional career is, don't get married to one technology or tool. It's OK to become an Access guru, but, like Andrzejek says, focus on the proper way to design the back-end and front-end of an application. That's what will benefit you most during your career.
Then, when you get a chance or opportunity, also learn Oracle, SQL Server, ProgreSQL, MySQL, MariaDB, etcSQL, etcSQL. A lot of times that's just a matter of noting the similarities and differences. You may have to learn a couple SQL dialects. But the benefit is, you become much more marketable. You're worth more to the company you work for, and finding a new job is easier if you decide to move on for whatever reason.
I know someone that got a degree in IT in the early 80's. The only language she knew was COBOL. She didn't want to learn anything else. She was a COBOL guru and made good money. By the early 90's, she was out of a job and couldn't find work. As the year 2000 approached (Google "Y2K bug"), she was all of a sudden in high demand. She had 6 to 8 months of intense work with a lot of overtime. Y2K passed and a couple months later she was back on the streets looking for a job. She hasn't worked in IT a single day since. All because she got married to a technology and didn't want to learn anything else. The world moved on.
We are in an field where the technology changes rapidly and moves forward quickly. If you are approaching it with the idea that once you get your degree, you're good to go, then you are probably going to have a very limited career. If you enjoy learning new technology, and just kind of geek out when something radically new comes along, then you'll do good. You are living in an amazing time. All the world's knowledge is at your finger tips. You just need to spend the time and effort.
