I got project in CRM SAAS development.
So they want to add custom field feature like saleforce.
I am not trying to match their scale, just want to get some information about the database engine and structure, so we can at least stay under best practice guideline for such case.
The options I have currently :
- JSON Column (Mysql / Maria recently supported this). / POSTGRESQL
Just not sure which is the best for my case above.
