In this article I will mention a specific issue that I experienced during my last GIS application and database upgrade.
The columnstore index in SQL Server 2012 stores columns instead of rows, and is designed to speed up analytical processing and data-warehouse queries.

When used appropriately, they can reduce disk I/O and use memory more efficiently.
A foreign key points to a primary key that must exist in another table, for example, column X in Table 1 must also be present in Table 2. The key protects this link, and only valid data can be inserted in the foreign key column. An untrusted foreign key may threaten a database’s referential and data integrity.
