I generally do not reveal too many details about systems I design for customers or employers. This leaves me sometimes in a bind for example material. I either have to simplify it beyond what I would like, or make something up that I have not actually put into Production.
On top of that, one of the key themes of this blog is that table design is a crucial skill, and if the examples I give do not match what you are doing, they may be hard to make use of.
So I would like invite analysis requests. Go over to the Contact the Author page and drop me an email and tell me about the system you are trying to design or optimize.
There are no rules on the type of system.
The most interesting mini-projects would be those where advice you have been given elsewhere (or here for that matter) does not seem to fit.
I will do my best to reply, even if I have to say no, so that nobody is left wondering.
Remember this blog is one of those hobby/professional things, good for all of us but nobody is getting paid, so if you are in a terrible hurry this might not be the best thing.
