Question 15: Which of the statements about database normalization is true? Statements: i) Database normalization improves data redundancy, saves on storage space, and fulfills the requirement of records to be uniquely identified. ii) Database normalization supports up to 3rd normal form and removes all data anomalies. iii) Database normalization removes inconsistencies which may cause the analysis of our data to be more complicated. iv) Database normalization increases data redundancy, saves on storage space, and fulfills the requirement of records to be uniquely identified. Options: - (i), (ii) - (i), (iii) - (ii), (iv) - (iii), (iv)

Instructions: Answer the following questions in the format specified by your instructor. 1. Figure 11–33 contains sample data for a Book table. Use this figure to answer the following: a. Is the table in first normal form (1NF)? Why or why not? b. Is the table in second normal form (2NF)? Why or why not? c. Is the table in third normal form (3NF)? Why or why not? d. Identify candidate keys for the table.

Figure 11–34 contains sample data for books and stores. In discussing the data with users, you find that book codes — but not titles — uniquely identify books and that location names uniquely identify store location. Multiple book stores can stock the same book. a. Convert the data in Figure 11–34 into a relation in first normal form (1NF) using the shorthand representation used in this chapter. b. Identify all functional dependencies using the notation demonstrated in this chapter. 3. Using only the data in Figure 11–33, how could you identify the entities and attributes that would be the starting point for a database design?

Transcript

00:01 Here from the given question, the correct statement regarding the given database of the normalization, the first, the option 1 and 2 are correct.

00:20 About database normalization, the option 1 and 2 are correct.

00:44 For the statement we have, the one is true because database normalization improves data retentancy, saves on storage space and fulfills the requirement of the records to be uniquely identified.

01:20 And is one of the primary aims of normalization to reduce the retentancy and inconsistency in the data while establishing unique identification within the records...
