a.    INDEX statement is used to create indexes in tables.
b.    An index can be created in a table to find data more quickly and efficiently.
c.    The users cannot see the indexes, they are just used to speed up searches/queries.
d.    Note: Updating a table with indexes takes more time than updating a table without (because the indexes also need an update). So you should only create indexes on columns (and tables) that will be frequently searched against.
17. Content Type ID Structure?
The content type ID of the basic content type Item is 0x01 (System: 0x, Item: 0x01). This denotes that the Item content type is a direct child of System. The content type ID of the Document content type is 0x0101, and the Folder content type has a content type ID of 0x0120.
