We use the SQL construct COUNT(*) to count the number of rows in a table.
Q3
In a 1:N relationship, the foreign key is placed in:
Q4
Multivalued dependencies create harmless anomalies that should be noted, but do not always need to be eliminated.
Q5
Normalization requires programmers to write more complex SQL.
Q6
One common design problem when designing a database from existing data is the presence of inconsistent values in the received data.
Q7
Which of the following column properties would be used to specify that cells in a column must be immediately filled with a monetary value of $10,000?
Q8
In a 1:1 relationship, the foreign key is placed in:
Q9
One common design problem when designing a database from existing data is the presence of missing values, called blank values, in received data.
Q10
Which of the following column properties specifies whether or not cells in a column must contain a data value?
Q11
Which of the following columns is(are) are required in a table?
Q12
Which of the following column properties would be used to specify that cells in a column must contain a monetary value?
Q13
The phrase "SALE.CNumber must exist in CUSTOMER.CNumber" is a referential integrity constraint.
Q14
One common design problem when designing a database from existing data is the use of a general-purpose remarks column in the received data.
Q15
When building a database from an existing set of tables, we may safely assume that there are no multivalued dependencies in the data we are given.
Q16
Which of the following data constraints would be used to specify that the value of cells in a column must be one of a specific set of possible values?
Q17
One common design problem when designing a database from existing data is the use of a single cell in one column to store multiple values of an attribute.
Q18
When you are given a set of tables and asked to create a database to store their data, the first step is to create the new database.
Q19
The design guidelines and priorities for read-only databases are different because read-only databases are never updated.
Q20
Which of the following situation requires the use of ID-dependent entities?
Q21
In all cases, normalization into BCNF is desirable.
Q22
Denormalized tables are in BCNF.
Q23
Proper normalization eliminates duplicated data.
Q25
We can eliminate modification anomalies with proper normalization that results in tables in BCNF.
