A fundamental way that SQL Server determines whether a principal has the permissions necessary to execute code is with its execution context rules. It’s all complicated by the possibility that a principal has permission to execute code but doesn’t have permission on the underlying objects accessed by the code, such as the data in a table. This stairway level will explore SQL Server’s execution context, ownership chains, and impersonation, as well as show you how you can control access to data via T-SQL code.
SQL Server Data Collector, together with Management Data Warehouse, is a fine and useful component for gathering information centrally about how SQL Server instances are being used, and thereby keeping an eye out for problems. It comes into its own when you have figured out how to configure it to run on maybe hundreds of instances using Central Management Server. Dennes describes how to tame the system so that it scales.
