well the first thing you should work out is archiving and how your system sorts this out , then fully optimize the systems to be able to work optimally , being a learning system (assumption) most of the data will stop growing since all that is changing is statuses , so your archive should be able to move students who have left and their data so that each year you're working only required data no reference data . Else for estimating this is what you need How many transactions does a student create in the system per month e.g. how many cats , assignment uploads , finall exams etc How much class work does the teacher upload every month/term (does this change and is it different per teacher in the same subject) the above will guide you to estimate that by the end of 1 yr 200 student transactions and 100 teachers transactions will have pushed data worth X Mbs On Fri, Aug 14, 2015 at 11:20 AM, Jangita via skunkworks < skunkworks@lists.my.co.ke> wrote:
Seems like a math direct proportion question from primary school :)
Anyway, is the 6.3GB ONLY the database data students and users? Or does it contain the operating system and supporting software (apache python, mysql binaries etc). To estimate space, I normally let the product run for several months and check daily/monthly usage. You might find that in April/August (school holidays) the data doesn't expand that much.
If your DB is structured correctly, space usage should be inversely exponential for a selected client base (master tables) from what I've seen of transactional systems (telecoms and banks)
If I were you, I'd watch for some time,graph then estimate

Dear members, I am trying to estimate the projected hard disk space usage by a web app; assuming the said web app is a school software;
*If 60 students and 40 users are using 6.3 GB of hard disk space, how many GBs will 100 students and 90 users use?*
Or is there a better way to estimate growth?
I am particularly at pains because students and users do not produce the same amount of data, therefore, I cant do 60+40 and use that. On the other hand, if I calculate for students kando and users kando, somehow that feels wrong because they will both use the same, well, hard disk...
