Assignment 2: Data Normalization—Avoiding Anomalies in the Database

In this assignment, you will analyze the role of data normalization in avoiding the three types of modification anomalies.

According to Edgar F. Codd, the inventor of the relational model of database design, one of the objectives of data normalization is to free the database of modification anomalies. In particular, normalization seeks to prevent three types of modification anomalies:

• Update anomalies
• Insertion anomalies
• Deletion anomalies

Tasks:

Using the Argosy University online library resources, scholarly or professional resources, your course textbook, and the Internet, conduct research on the three types of modification anomalies.

Based on your research, create a 3- to 5-page document in Microsoft Word, which includes:

• An explanation of each type of modification anomaly and how each of these anomalies arises
• An analysis and description of the use of the normalization process and how the normalization process seeks to prevent modification anomalie
