I was a slow started. At the age of 50 I had the opportunity totake a Masters course in Computing. Basically I am a time served engineer thathad got into using a computer and systems as part of my engineering job. Had no qualifications in computing.
Degree exposed me to databases and Access. The veil lifted from the eyes. Basically then started applying Access to everything. Some mistakes but learnt a lot. Found this forum... Learnt huge amounts. Did teh OU course on Databases. Re inforced the background of databases. Normalisation, Normalisation , Normalisation. I hear people say "What". If you do not understand Normalisation you are basically dead in the water. If not now then certainly later without a doubt.
Then experience. No substitute for this. You then learn when Not to apply Access but you also see wonderful, exciting opportunities for its use.
If you intend to really get stuck in then get all the training you can. Access is a brilliant grounding if you want to go further. It is however somewhatderided by those that do not really know what they are talking about. It is the best RAD tool about by far. I would always say, Develop in Access then migtate upwards SQL maybe Oracle if required. Oracle is overpriced and over rated in my opinion, It has its use. Huge numbers of concurrent users or really huge amounts of data. Apart from that it is an expensive hammer to crack a peanut. Some may disagree but we all have opinions.
Because Access comes with Office there are a vast number number of people who think they are database developers. They do not have a clue and make fundamental mistakes. Search the forum on Normalisation and you will see just how many times teh gurus on this forum point out that Normalisation or lack of it is the basic problem.
So there are a few words, Quite a lot actually.
My advice. Spend the money on OU to get good grounding on techniques and the real underlying knowledge that is essential to understand ALL databases, Oracle, SQL etc. They are all basically the same.
Exploit every opportunity you get to use and develop databases cos that is where you will learn.
