Do you agree than any of these test cases are possible in the real world?
1. The Multi tenant blog system is hosted on a large shared hosting company giving full access to any DBA(of said shared hosting company) to freely write a select statement allowing them to export all your data into a CSV file for later reuse.
2. The Multi tenant blog system is hosted on a Virtual Private Server at a hosting company where one Blog Tenant A receives a large amount of traffic causing locks in the database and due to an error with MS SQL server the wrong database record is returned in a SELECT statement to other Blog Tenants B, Blog Tenants C, Blog Tenants D on the same Virtual Private Server.
3. An error in coding causes the wrong data(from Blog Tenant A) to be served up Blog Tenant B.
