Under this tab, the Desktop Area section controls the screen resolution settings. I strongly urge you to develop, in your own database-design work, the habit of never including white space in field names, just to prevent possible later difficulties.
Access often uses a dot notation to associate fields with the tables to which they belong.
You can safely ignore the discussion, as well as Exercise 2 on page 69. On page 47, Cassel and Palmer first mention SQL, the Structured Query Language. Access will display the SQL statement that underlies this query. For now, just note that the SQL statement contains capitalized words, which are reserved words in the formal vocabulary of SQL, together with the names of the fields in the various tables with which the query deals. If you enforce referential integrity, Microsoft Access prevents you from adding records to a related table when there is no associated record in the primary table, changing values in the primary table that would result in orphan records in a related table, and deleting records from the primary table when there are matching related records in a related table.
