Using Hubspot as a full blown user database / LMS?
We run an online course business, and we're integerating all our systems with Hubspot via API.
I'm wondering if it's a good idea to take this to another level and use Hubspot as an alternative to our slow MySQL database, and use it as a base for our custom LMS.
This will mean we'll store students' progress and even homework answers as properties in Hubspot. It will mean each contact will have over 300-400 properties.
The question is -
1. Is there a reason not to do this?
2. Will this work fast enough via API? (compared to MySQL queries from PHP)
