Discuss what normalization is and why it is important. Normalize the database design in Module 2,

Module 3 Case: Database Normalization, Employee table

INSTRUCTIONS:

Module 3 - Case NORMALIZATION AND SQL DDL STATEMENTS Case Assignment In this assignment, you are expected to accomplish the following: Discuss what normalization is and why it is important. Normalize the database design in Module 2, and describe whether the tables are all normalized. Explain whether the tables satisfy the requirements of 1NF, 2NF, and 3NF. If you believe your tables as submitted in Case 2 are already normalized, explain in your paper how those tables meet the normalization standards. If not, how you would modify the design? Draw or describe your new database ERD the same way you did in Module 2 in the paper. Describe (in at least one paragraph) what ACID is and why it is important for databases. Describe (in at least a half page) why normalization is needed and how to optimize it. Describe lessons learned from this exercise. Include in the paper the SQL statements used for creating tables and screenshots of the results in your chosen DBMS. Assignment Expectations Normalize tables in a database design. Be able to use SQL to create tables and indexes. Briefly discuss the pros and cons of normalization.

Normalization Name Institutional Affiliation Database Normalization In the design and development of a database, it is essential to ensure that the structure provides efficiency and enhances the handling of data by the database system. Technically, the process of organizing the structure of the database while designing it by ensuring that the tables are in their minimum form to reduce redundancy is referred to as database normalization (Rouse & Vaughan, Database Normalization, 2016). The aim is to remove duplicates from the tables. In addition, the database normalization is critical in determining the dependencies in the database such that the data is logically integrated. A comprehensive database normalization process ensures that future incidences of data loss do not occur in the process of handling and updating the database (Harrington, 2
