Rough starting outline:

Read Operations
        (How does a read work?)
    Collection Read
        (how it works, what tables)
    Index Read
        (how it works, goes from index table to collection table -- two lookups)

Definitely feel free to alter the layout and file additional tickets split the work into more manageable units. Please add topics if you can think of any. This outline is meant only to be a starting point.
