You're totally right, and one of the limitations on the info I was able to include was that it's very difficult for me to know how to describe what we're trying to do, not having the expertise. We seem to be trying to find a SaaS solution that will allow us to store academic records, and is flexible enough to accommodate things like student work samples, assessment data, and other forms of information that we might not completely anticipate.

I know we can't build what we need from scratch, and I know that we need something more sophisticated than a NAS- we don't want to invest the capital and time to create an inhouse technology stack, we use google apps for our student and staff accounts and document hosting, and it seems like our data storage needs to be a similar kind of managed database product which allows our office staff to input new records through internal web forms and similar approachable tools.
