lcTaskList Performance

Peter,

Suppose there was a database built with LiveCode, that required no SQL, that worked with your data, that made your data multi-user, that provided encryption for the network, that ran really fast, that let you tweak your data and interface as you wished?

Would this interest you?

I have continued this antiquated structure for several reasons: my customized search routines depend heavily on HC/LC's find and mark commands, which are blindingly fast, and to try to duplicate even some of the functionality using database searches would be prohibitively labor intensive -- I really don't have the time to learn SQL commands given that I already have three half-time jobs. Not to mention all the other wrinkles I would have to iron out to change to a database-centered system. I know I have painted myself into a corner here, but my system has worked so well up to now and is so complex that making the paradigm shift is overwhelming.

If I were in a position to devote more time to it and it had a future that could be ported into a commercial venture, I'd tackle the job, but everyone in the medical field is moving towards electronic medical records and my system was designed from the beginning to print hard copy paper notes for a paper chart. To move this thing into an electronic medical record system would require me to learn networking and encryption along with the database management (not to mention developing an intimate familiarity with the HIPPA laws regarding medical confidentiality). I am essentially just a (pretty experienced) LC hobbyist with another profession that I have used LC to support, not a real IT person. I'm not prepared to create an entire EMR system single-handedly.

My group practice is about to adopt an EMR system this summer, so I will not be able to use my own customized LC system any more. I am not looking forward to having to use a piece of software that I can't tweak at will to make it do exactly what I want it to, and I'm preparing myself for daily cursing as I use the new software. (The two other psychiatrists in the practice that use Psychopharmica are also feeling bleak -- they appreciate how nicely this software is attuned to the actual workflow of a busy practice, and it's about to die.)

It's been 20 years now that I've been spoiled by having a truly perfect tool -- one that evolved with my needs, not someone else's. Now it's time to say goodbye.
