I know "here he goes being a problem AGAIN" well :wildone: :crazy1: why not both
though for this scale i suspect that at least a few of the con's for the web one will not really be a problem. i also see some of the con's for the desktop version not being a problem either
will I use it, donno, might, ive got a LOT of records to convert, but i just might consider it, how much will I make public, probibly all of it as i dont need to hide my secrets from my neighbors
i dont understand you say a month to release a beta does that mean you have some kinda life or job ????
as I run quickly and far for cover
if your into doubling up the efforts I wont mind doing the web work to have a beta out in a month ish, assuming we can come up with a data structure that we can agree on

, and features we can impliment in both in a beta release.
as for privacy I see it as a 2 part thing, users who used the web one would have to trust those that set it up that the information they desired to keep private was kept private, but a simple check for private box seems to work for me ???
the structure I see starts with a 2 part key a date and a system description, the date would be the date it started, then as tanks/filters .... were changed they would be added in another table [tanks] and [filters] with descriptions and dates as the PK then from there you have a [breedingfish] with date and tank as the PK if you moved the fish then a new record would be started using the origional fish and a new tank, then other tables for things like larva, rearing, growout and food sources and such.
this establishes a timeline, the timeline itself would have to be handled in SW not the DB but will be easy to impliment in either. you just start at the top "system" and filter down to whatever was connected to it. selecting all of the filters connected to system, then all the tanks, a "end date" field would signial that the tank was to stop at some point on the timeline.
i started a visio thing on it, but while i dont have a life i am stuck at work

so my play time is limited.
