See the example in Chapter 7, "Refreshing Materialized Views". database administrator thus needs to define the data relationships between views rather than tables. How do SQL views compare to ANSI/SPARC external schemas /user views?. the SQL DEFAULT constraint with the CREATE TABLE command. Chapter 8.
