If at all possible, you should normalise information in your database using Codd's principles of database normalisation. Basically, this means that you don't duplicate information, store information that can be recalculated based on other fields, or store more than one piece of information in a sin ....

58 - Call Centres, selling, and a pause for thought

Have you noticed that telephone calls you "have to" make to renew a service are now being taken as an opportunity to sell to you? It happened to me just the other day when I called in to confirm receipt of a new credit card. "While we're waiting for the computer to authorise you, can I just ask you ....

57 - Posting 1000 letters!

We do a big mailing of over 1000 newsletters twice a year, and we never know quite how the local Post Office is going to receive us when we walk in pulling a trolley stacked with 120Kgs of franked mail. Get a "jobsworth" on the counter, and they'll insist that you pass over the envelopes in bunches ....

56 - Dress Code

I was told during last week's course that I'm much more approachable that I look in my picture and I'm delighted with that, though at the same time wondering if I should change the picture concerned to one that's a little less formal. I'm following a conversation on a list server concerning dress f ....

55 - Evening classes to learn PHP

I've often felt that the best way to learn a subject such as PHP would be to take half a day of training per week over a period of perhaps 8 to 10 weeks. Practicals exercises to try between each week's session, with the tutor starting each session / lecture with a review of issues that trainee have ....

54 - PHP and natural sorting

If you sort (8, 9, 10, 11, 12), how do you want them to be output? "In the order you've just listed, Graham", you'll probably say. But if they're strings and you sort them, then you'll get the order 10, 11, 12, 8, 9 output if you just use a default sort, because the character "1" comes before the ....

53 - Drive the drive

Our training centre is in an old Georgian Lodging House on the outskirts of Melksham, Wiltshire. Well set back from the road, long driveway. Plenty of parking, and quiet. Just a bit of a nuisance when we get a major delivery, as our historic gates have just 9'4" clearance ... Yesterday, a big artic ....

52 - International awareness

I never cease to be amazed by how international the world has become - with travel from country to country being the norm. "If it's Tuesday, it must be Belgium". Yet at the same time, there are laggards and at times the USA seems to have more than it fair share of these. Perhaps that's just beca ....

51 - Gym and swimming - Melksham Blue Pool

When you're away from home on a training course, why should you have to take a break from your fitness regime if you're that way inclined? Our training centre is less that a mile from the Melksham Blue Pool, open from 7 in the morning into the evening. We work closely in conjunction with them to e ....

50 - Current cost in your local currency

If you're selling internationally on line, it's a nice gesture to your customers to tell them roughly what things cost in their local currency, before you charge their credit card in pounds, dollars, euros, or whatever currency you use yourself. Tables of current exchange rates are easy enough to f ....
