Database Design Using Normalization
If a table has been normalized so that all determinants are candidate keys, then that table is in:
When assessing the table structure of an acquired set of tables with data, counting the number of table rows is (part of) the:
Each answer below shows example data from a table. Which answer is an example of the missing values problem?
In all cases, normalization into BCNF is desirable.
Denormalized tables are in BCNF.
Normalization requires programmers to write more complex SQL.
When building a database from an existing set of tables, we may safely assume that referential integrity constraints have been enforced on the data we are given.
One common design problem when designing a database from existing data is the use of a general-purpose remarks column in the received data.
Most of the time, modification anomalies cause problems that are severe enough that a table should be normalized into BCNF.
We use the SQL construct COUNT(*) to count the number of rows in a table.
