When most DW designers begin developing a data warehouse, the Time dimension is the first dimension reviewed with the users. There are usually two or three different persectives on what the Time dimension should represent but, for the most part, it will be used for such calculations as Year-to-date Sales, Monthly Inventory Churn, etc. What most users are actually describing is a Date, or Calendar dimension.

The File Watcher Task does what it says really, it watches a folder waiting for files. When an available file is found the task completes, returning the name of the file for later use.
The task will detect changes to existing files as well as new files, both actions will cause the file to be found when available. A file is available when the task can open it exclusively. This is important for files that take a long time to be written, such as large files, or those that are just written slowly or delivered via a slow network link.

We all know the "TOP" clause returns the first n number of rows or percentage of rows thereby limiting the number of resulting rows displayed when we are selecting rows in a table.
SQL Server 2005 is packed with new features and enhancements. One of the enhancements in SQL 2005 that we are going to see is the clause, "TOP." The "TOP" clause will now allow us to do Data Manipulation and also allow similar criteria results to be displayed by using the TIES option.

There has been a lot of interest in the web-facing community lately about a new useability feature that goes by a number of different names—XMLHTTP, AJAX, out-of-band requests, and asynchronous client script callbacks, to name a few.
Regardless of the name, this feature provides a way for a standard web page to make calls back to the server, without a traditional page refresh. The user is oblivious to the fact that a server call has occurred, and is not interrupted by it.

n this lesson, we will examine another function / property in the MDX toolset, the .UniqueName function. The general purpose of the .UniqueName function is to return the Unique Name of the object to which it is appended. .UniqueName can be used in conjunction with hierarchies, dimensions, levels, and members, in a manner similar to the .Name function that we examined in String Functions: The .Name Function, and, also like .Name, .UniqueName can be useful in a host of different applications.
