Figure 6-4: The node set returned by XPath Evaluator. Note The preceding expression is an abbreviated form that could have been more precisely expressed as follows: NorthwindEmployees/Employee/self::*[child::employeeid > 7] You apply the predicate to the context node in person (self) and verify that the employeeid node on its children has a value greater than 7.

Choosing a Light or Dark Site Theme You have presumably chosen your color pair, but now you need to consider how you want to use those two colors on your site. Your two primary choices are a light site theme or a dark site theme. Choosing either light or dark will determine the dominant feel of the site. Suppose that your two colors are black and white. If you make your text black, it s likely a majority of the display will be white, like black lettering on a sheet of white paper. That means that your site will likely appear shiny, bright, light, or airy to a visitor. Such a scheme might be perfect for a touring bicycle site, a small-town bakery, or a search engine like Google. It might not be the best choice for a site representing a jazz club or a new first-person-shooter videogame. On the other hand, if you make the text white, the majority of the remaining space will be black. That produces a completely different effect, doesn t it The site might feel solid, edgy, mysterious, or lush. This theme might be perfect for a hip sunglasses manufacturer or an investment bank. It might not be the best choice for a handicraft or computer dating site. More realistically, you may have chosen a very light yellow and a very dark blue. With those selections, setting the text in the blue and the background in yellow will produce a light site theme. Doing the opposite, with yellow text on blue background, will produce a dark site theme. Select how the colors will be used on your site now, so you can more effectively generate the hues that you will need.

Now let s talk about statistics created by the CREATE INDEX statement on an index partitioned on a column that is not the leading column of the index key. To understand the problem we rst need to understand the history of the relationship between indexes and statistics in SQL Server. SQL Server in releases prior to 7.0 created statistics only as a by-product of index creation. When an index is created, SQL Server must read the table, order all index key values,
