When I was younger we frequently went camping. This trip felt like we were camping, but I forget if this particular trip was a planned camping trip or just an outing where my Father was helping a friend with chopping up some felled trees due to clearing some land. I remember being so excited about being able to take the small hatchet we had always kept by the fireplace.

I was finally old enough to wield that cool looking ax. The one I had always wanted to snatch up and start swinging around like some crazed arena fighter. Sharp, shiny, hard and heavy, I knew this was a cool tool (especially to boys), and I wanted to use it about as badly as that cool sword shaped letter opener my Grandfather had.

We get to the site, and I start whacking like crazy at the myriad of trunks scattered about the ground. Despite my careless abandon, I remember the incident to this day. My Father was helping out this friend who had not worked with a chainsaw before. While the unknown horrors could be imagined that this friend lost a leg or something worse, it was a bit more mundane, but still a lesson to be learned.

You see, while using a chainsaw, if the tip catches on something, even the log you're sawing, the chainsaw can kick right back into your face. While this was a very minor kickback incident (no injuries this time) and turned out to be a good lesson, I remember it well - as my Father told us both about how to avoid this potential hazard.

Switching over to the world of FileMaker and the design of your database, there are a number of things in your solution which could become hazardous kickbacks - although none that will physically take off a leg. The topic of this video covers one of those potential issues and shows you not only how to avoid the issue, but how to approach your development. You have to think about every action and its consequences.

The current state of the example KarateApp database leaves us with a problem and a solution which will help you in many other similar situations. This video is certainly one worth watching if performance impact is of interest to you!
