Hmmmm
I've actually been performing magic for more than a few decades and serving as a development consultant for at least 25 years if not longer. NEVER in all that time have I ever had the need for software and data bases... it's an action that seems to be reinventing the wheel in my mind.
If one were to keep an index of every routine you actually know, details on how you personally perform it (in that we all have our little changes) then you are doing what magicians have done for centuries... keeping a log or notebook; one that you will hopefully go back to from time to time, so as to remind yourself as to the things you have done and how they may fill the niche you need filled in some new bit being developed.
Notebooks of this nature are priceless in that they preserve that aspect of magic history few ever learn of.
Though I can see the logic behind such an electronic file system I also see its coldness and the potential of its loss. One simple crash of your system, one bug or virus and voila!
I'm not trying to put down this idea, I'm only encouraging folks to think long and hard when it comes to just how practical it really is, not to mention situations that appear to be quite positive testimonials that smell more like bogus new members... if you know what I mean.
If you have Office or a similar foundation software, you can replicate most everything being offered in this software idea without the risk of having YOUR notes and YOUR secrets "borrowed" and later published or even credited to someone else. You lessen the risks of loosing that material in that you have your own back up in place and do not have to use a specific "rare" software for access... especially when the idea may fail and no longer prove available or else you find yourself in a classic Green Place course of pettiness and get "cut off"... not that magic is full of petty people and political game players or anything
No... I have to say BUYER BEWARE and more so, I'd have to encourage you to stick with what's worked for more than a few hundred years. Handwritten journals are one of the treasures of magic no matter who composed them. Many have been found a generation or two after some obscure person's passing, revealing a master piece of theory and "new" effect concepts never before known to our fraternity; a testament about a life and how a fallen fellow processes their thoughts.
Can you imagine just how horrible it would be, to not have the Sielbit, Harbin and Thayer notebooks today? The loss of the Houdini and Thurston journals?
There's so very much more and we owe it to our industry to make certain our words are preserved in hard form, not just on some data base that will eventually prove obsolete or worse, deteriorate and thus, loosing everything we've entrusted to it (solely).
Just some thoughts...
