Hi Norfolk Newbie, I'm inclined to agree with doganjo Annie. Microsoft have their critics and cynics, but they've been in the field a long time and have rather established industry standards. Specialist programmes may be better for a full-blown business, but there are better things to spend your money on, especially these days!
One (of many) valuable attributes I've found with Access (databases) and Excel (spreadsheets) is that you can VERY easily migrate or connect data between them, or use a spreadsheet or database (usually a 'Query' within the data) as the source for a mail-shot, address labels, or other mail-merges. You can also insert hyperlinks to connect web resources into something you're building/developing for your own use. It saves copying and pasting pages (and using up your memory), and means you always get the up-to-date web-page when you use it.
Doubtless, there are talented teenagers who'd scoff at my reactionary views, while themselves capable of rattling off a bespoke system after lunch one day...! But as I'm not one of them and havent any to hand, I'll settle for the proven reliable Microsoft Office product, acknowledge it does have quirks, and get the best out of them for what I want.
Also, training and advice is more available for them. The 'European Computer Drving Licence' (ECDL) is a recognised I.T. qualification that's based on MS Office software, and is the standard for people using I.T. in their work. You'll probably be able to enrol on a local Adult Education class based on ECDL, or find something in a local library to help get you started. And there's loads of stuff on the internet, too (obviously...??).
Good luck! John
