Business Rules

Nowadays there is a lot of pressure on the middle tier of the three tier stack from both the database and the smart client. If technologies such as Yukon allow all the code to run in the databases is the business tier of logic required? Whilst the actual physical implementation of the business tier as…

Electricity as a Managment tool

Physical phenomenon can not only be used as a valuable architectural training aid but they are also useful for management training, especially handy when trying to free up budgets!   I was talking yesterday about designing power supplies for TV monitors and some of the hazards associated with that.

Architectural thinking

In my last blog I hypothesised that Architectural analysis is slightly different from developer analysis and so needs a subtly different skill set and way of thinking. To demonstrate what I mean let me describe a real life example of an architectural problem and different solutions.   I was called up late one Friday afternoon…
