1. Which of the following is a group of one or more attributes that uniquely identifies a row?
2. 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):
3. A relation is considered a:
4. In the relational model, relationships between relations or tables are created by using:
5. A functional dependency is a relationship between or among:
6. Table is synonymous with the term:
7. Which of the following is not a restriction for a table to be a relation?
8. For some relations, changing the data can have undesirable consequences called:
9. A key:
10. An attribute is a(n):
11. A relation in this form is free of all modification anomalies.
12. If attributes A and B determine attribute C, then it is also true that:
13. A tuple is a(n):
14. If attribute A determines both attributes B and C, then it is also true that:
15. One solution to the multivalued dependency constraint problem is to:
16. In a relation, the order of the rows matters.
17. In a relation, the rows are sometimes called "records."
18. Any table that meets the definition of a relation is said to be in first normal form.
19. Given the functional dependency R → (S,T) , then it is also true that R → S.
20. A candidate key is a determinant that determines all the other columns is a relation.
21. The only reason for the existence of relations is to store instances of functional dependencies.
22. A relation is in 5NF when multivalued dependencies are isolated in their own relation.
23. The functional dependency R → S means that the value of S can be determined when we are given a value of R.
24. In a relation, the columns are sometimes called "attributes."
25. In a relation, the order of the columns does not matter.
