A database schema is the definition of how the data is stored in the database file. As shown in Table 6-1, in all earlier versions of Exchange Server, each database has a mailbox, folder, message, and attachment table. These tables are used to store all information for all mailboxes in the database. This provides the ability to only store a message and attachment once for each of the mailboxes in the database. The previous database schema also includes a table for each folder to store the item contents of each folder.
