Denormalized tables are in BCNF.
Most of the time, modification anomalies cause problems that are severe enough that a table should be normalized into BCNF.
Read-only databases are ________ updated.
When assessing the table structure of an acquired set of tables with data, determining foreign keys is (part of) the:
Each answer below shows example data from a table. Which answer is an example of the missing values problem?
One common design problem when designing a database from existing data is the use of a general-purpose remarks column in the received data.
Needing to using more complicated SQL in database applications is a(n) ________ of normalization.
We use the SQL construct COUNT(*) to count the number of rows in a table.
We can eliminate modification anomalies with proper normalization that results in tables in BCNF.
Proper normalization eliminates duplicated data.
When building a database from an existing set of tables, we still need to consider normalization principles.
We have normalized a table into BCNF if all candidate keys are determinants.
Needing to assess the validity of assumed referential integrity constraints on foreign keys is a(n) ________ of normalization.
Creating a read-only database is a task that is ________ assigned to beginning database professionals.

When assessing the table structure of an acquired set of tables with data, determining functional dependencies is (part of) the:
One common design problem when designing a database from existing data is the presence of missing values, called blank values, in received data.
