I hope this helps.

–Don’t just write a rehash of Books Online. Try to offer some new perpectives.

–Would like to see specific examples of how indexes are implemented. In other words, include less theory and more real-world, practical advice.

–Include a discussion of the most common indexing mistakes, and how to avoid them.

–Keep the content easy to read, so that it doesn’t melt your mind.

–Include a discussion of “covering indexes” and how they should be implemented.

–The easiest indexing concepts to understand include the types of indexes, such as clustered, non-clustered; what happens when you have too many indexes; the problems caused by index fragmentation. Some of the harder parts of indexing include: indexing internals, such as how they are stored and accessed.

–When should clustered indexes be used? When non-clustered indexes should be used?

–Discuss how to identify missing indexes, unused indexes, or duplicate indexes.

–How does indexing work with LOB objects?

–What’s the best way to maintain indexes?

–How do you identify the ideal fillfactor for an index?

–Include how statisics are related to indexes, but don’t overdo it.

–How do you use Management Studio to manage indexes?

–What DMVs can you use to “peek inside” indexes?
