Secondary indexing is simply the task of determining other indexes to add to a database to make queries more efficient. It is called secondary indexing because when you defined the identifiers earlier in this chapter, every table in your schema got a primary key index to make searching by primary key very efficient. There is a cost for indexing in that as new values are added to your tables, the indexes must be updated with any new values that must be indexed. With this in mind, you will want to create as few indexes per table as possible but add indexes judiciously where necessary. You are probably responsible for making sure that indexing is efficient when you recommend a data schema. That doesn t mean that you can t elicit advice. If your company employs database administrators, you should use them to help you make smart indexing decisions. When you want to determine what secondary indexes you need, you will want to look at what types of data in the schema are likely to cause searches that do not use the primary key. For example, you might choose to add an index on the Order table s OrderNumber field so that searching for an order by its order number is a fast search. Adding secondary indexes during the design mode can only get you so far. Typically, indexes will need to be tweaked once a project is delivered to help make real-world searches perform better. Using tools like SQL Server Profiler and SQL Server Database Tuning Wizard will help improve the performance of a running database.

Figure 3-3: Detailed information about a WIM image Mounting WIM Images If you want to manage an image, you first need to mount it. To mount the W:\Myimage.wim image on (for example) the C:\MountedImages folder, you enter the following command in the elevated Deployment Tools command prompt: dism /mount-wim /wimfile:w:\myimage.wim /index:1 /mountdir:c:\mymountedimages The /index flag in this command indicates the image that you want to mount. You can have several images (for example, several editions of Windows 7) within a single WIM file.

Be aware that the ISNULL function is not the same as using the IS NULL clause in a query. The IS NULL clause is just used to detect whether the NULL value exists, whereas the ISNULL function will actually replace the NULL value with a replacement value.
