I have no idea if they are any good, or if they are suitable for you as I don't know what your IT knowledge is. You should also get your boss to buy you a book on how to use Access.
Access 2003 is pretty simple depending on what you want to do. If you have ever used any database before then it should be easy.
If you have never used a database before it might be difficult to learn. If you have any questions you can feel free to ask me and I will do what I can to help. :)
It is quite possible to transfer an existing Excel spreadsheet into Access, but there doesn't seem much point in doing so.
You really need to find out more about what a database is and why you would use one before you start using Access. This isn't something that someone can easily explain to you via an advice forum. If you and your boss are serious about you using Access, you either need to do some training or start reading "Access for Dummies" (or whatever introductory book you can get).
Hkkm, I need to have old excel files converted to Access coz my boss wana use filter. The reference book I’ve got called teach yourself access 2000 visually bu marangraphics gives more info than I need.
