The Relational Model and Normalization Questions

• A relation is considered a:
• Row is synonymous with the term:
• The different classes of relations created by the technique for preventing modification anomalies are called:
• A relation in this form is free of all modification anomalies.
• One solution to the multivalued dependency constraint problem is to:
• A relation is in this form if it is in BCNF and has no multivalued dependencies:
• If attribute A determines both attributes B and C, then it is also true that:
• A tuple is a(n):
• Every time attribute A appears, it is matched with the same value of attribute B, but not the same value of attribute C. Therefore, it is true that:
• Which of the following is a group of one or more attributes that uniquely identifies a row?
• A key:
• An attribute is a(n):
• If attributes A and B determine attribute C, then it is also true that:
• The primary key is selected from the:
• In the relational model, relationships between relations or tables are created by using:
• Table is synonymous with the term:
• For some relations, changing the data can have undesirable consequences called:
• Which of the following is not a restriction for a table to be a relation?
• A functional dependency is a relationship between or among:
• When the values in one or more attributes being used as a foreign key must exist in another set of one or more attributes in another table, we have created a(n):
