Easy answer here - nearly every LOB app we have uses MSSQL.

I've had engineers want to talk about syncing it to MySQL using some custom plumbing so that they can build a reporting infra around their MySQL stack, but it's just another layer of complexity over having code just use Microsoft's reporting services.

I'll add, having finance people with Excel really like being able to pull data directly from MSSQL, they do not like hearing about a technican's python app.
