A view is a virtual table that consists of columns from one or more tables. Though it is similar to a table, it is stored in the database. It is a query stored as an object. Hence, a view is an object that derives its data from one or more tables. These tables are referred to as base or underlying tables.

The Checksum Transformation computes a hash value, the checksum, across one or more columns, returning the result in the Checksum output column. The transformation provides functionality similar to the T-SQL CHECKSUM function, but is encapsulated within SQL Server Integration Services, for use within the pipeline without code or a SQL Server connection.

Usually developers like having full control over their reports but what happens if you have someone designated to build reports who does not quite know the backend schema. A good way to separate the building of the data for the report and the report design could be stored procedures. Now I consume stored procedures using Oracle which is not much different consuming stored procedures with SQL Server, however building the procedures is much different between the two. Even though I mention and show examples of stored procedures this is not an article for building them, just a guide for consuming a stored procedure within a Reporting Services Report.

The dynamic management views (DMVs) in SQL Server 2005 are designed to give you a window into what's going on inside SQL Server. They can provide information on what's currently happening inside the server as well as the objects it's storing. They are designed to be used instead of system tables and the various functions provided in SQL Server 2000. This article provides an introduction to DMVs and covers a few of the basic views and functions.

Data, information, and knowledge. They're all different concepts and we sometimes lose sight of the fact that there are differences. This is a good look at the difference.

In this article, we will begin an extended examination of the MDX surrounding drilling up and down within our Analysis Services cubes. Comprising an analytical technique by which an information consumer can maneuver between summarized ("drilling up") and detailed ("drilling down") levels of data, drilling up or down occurs along the lines of drilling paths that are defined within the physical structures of our cubes. Often specified by the cube's dimensional hierarchies, these paths can also be based upon alternative relationships that exist within or between dimensions.

While doing some testing of an application, I wanted to reset my environment after doing some testing with this code:
USE DNRTest BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak' GO /* Bunch of stuff tested here */RESTORE DATABASE DNRTest FROM DISK = 'dnrtest.bak' WITH REPLACEWhat happens if this runs, assuming the "bunch of stuff" isn't anything affecting the instance. See possible answers
