This time I write about a simple pattern which could make the readability of your code much better. I’m talking about the “Template method pattern”. The pattern defines the skeleton of a process without implenting it. The real implemenation is handelt in another codeunit.

Contributing to “ALGuidelines.Dev”
I recently blogged about this new initiative .. the revival of the “NAV Design Patterns Wiki”: ALGuidelines.Dev . Time to talk a bit more on how you can contribute. I’m documenting this while I’m writing my very first pattern 😉 (I admit, I had this blogpost laying around for a while ;-)).
