Description

Prior to beginning work on this assignment read Chapter 9 of your textbook, review the Microsoft Create a Database website and review any relevant information in this week’s lecture. Review the chapter readings and the website to learn more about the process of creating tables and related attributes.

This assignment will be completed within the Virtual Lab Environment. For this assignment, you will access your virtual Structured Query Language (SQL) server, create a database and translate the normalized ERD from the Week Three assignment into the SQL server entities. Within the SQL server database all the following requirements must be met.

  • Create all entities with appropriate attributes
  • Select appropriate data types for all fields
  • Translate business requirements into integrity constraints
  • Build the ERD using the SQL Server Diagramming tool

Once you have created your SQL server database you will create a document. Take screenshots of the ERD and each of the individual tables within the database and paste these with appropriate labels into the document. You must submit the document via Waypoint for grading. Your instructor will also review your SQL server database within your virtual lab for grading purposes.

The assignment

  • Must be six to eight screenshots in length and formatted according to APA style as outlined in the Ashford Writing Center.

1 The Normalization Process: Converting the ERD Audrey Lane-Kinney The University of Arizona Global Campus ISM 641: Database Design and Management Robert Rossi April 26, 2021 2 The Normalization Process: Converting the ERD Normalization is a multistep process that is executed on data models to attain optimal database design. When a database is at the minimum (first normal form), the user is determined to normalize it to the 3rd normal form. Ideally, the urge to normalize the database further is still there, which requires normalizing to the Boyce-Codd Normal Form. The utilization of the fourth and fifth normal forms is far less common despite their existence. Therefore, normalization refers to the progression of proficiently organizing data in a database. The process comprises multiple steps known as forms, and the array of forms commences from 1NF to 5NF. The normalization process is essential in diminishing intricacy and redundancy as it critiques the novel data sorts utilized in a table. It is beneficial to split the larger databases table into smaller tables and connect them utilizing relationships. The process circumvents repeating groups as well as duplicates data in a table. Nevertheless, normalization has several downsides in the count of generating a longer task. Since there are more tables to link, the necessity to connect the various tables intensifies, and the task becomes more monotonous (longer and slower). The database becomes harder to realize as well. First Normal Form (1NF) Every table holds the comprehensive nuclear data elements, no duplicate data, and an allotted primary key (no duplicate groups) in this phase. A table in the first normal form contains no duplicated rows and atomic, meaning no duplicate arrays or groups, and each cell is valued. The first normal form tables have the same types of entries in the columns, and each row comprises analogous columns. Besides, the order of the columns or rows is less significant, and the table has a primary key because it contains no duplicated rows. 3 For instance, in the product table, the product modules and the product details must be keyed in distinct fields and not parted by commas. The modules or classes of data must be shifted to a new table with a link back to the predominant table, commonly referred to as the foreign key. Product Table Product ID Product Names 1 Mac-book air 2 HP Company Name Apple Inc Company Location California JPMorgan Chase & New York Co. Taken Modules Table Product ID Supply ID Modules 1 1 Introduction to PCs 1 2 Firewall Architecture Second Normal Form (2NF) In the 2NF step, the redundant data is disregarded. Therefore, if an attribute depends on only part of a multivalued key, it must be moved to a separate table during normalization. A table to be in 2NF should meet the entire database requirements surrounding the first normal 4 form. If every single non-key trait is entirely functionally reliant on the entire primary key data, that does not rely on the table's primary key directly. Then, in such a scenario, the attribute must be shifted into another table. A user has to formulate if the primary key imposes every single non-key attribute. It is not possible to determine the attribute's values with any subset of the primary key. In the second normal form, a table should have the comprehensive nuclear data attributes, a designated primary key to eliminate chances of duplicate rows and have no repeating groups. Also, every table should have entire non-primary key traits copiously reliant on the unabridged primary key. Supplier Table Supplier ID 1 Supplier Names John Kellick Corporate Name Apple Inc Corporate Location California JPMorgan Chase & 2 Laura Grey New York Co. Modules Table Supplier ID Module 1 Introduction to PCs 2 Firewall Architecture 5 Third Normal Form (3NF) Suppose a table meets all the database requirements for 1NF, 2NF and is without transitive dependencies. In that case, it is in 3NF, i.e., each column is directly dependent on the primary key (PK), and all attributes not dependent on the PK must be eliminated. It is aimed at reducing redundancies and maximizing the data integrity. 3NF meets the following criteria: 1. Each table stores all-atomic data items without repeating groups and with a designated primary key. 2. Each table has all non-primary key attributes whose functionality is fully dependent on the whole primary key. 3. The tables do not have transitive dependencies. EXAMINATIONS Score ID Student number H12/BSC/16 2745 Course Code Marks Course Name Total Marks BSC/202 75 BSC IT 75 From this table, the course name is dependent on the course code and the student number. Additionally, the total score is dependent on the course name. With the primary key in this table being Student_ID + Subject_ID, all attributes are dependent on it except for the total score; 6 transitive dependency. Therefore, to arrive at a 3NF, this transitive dependency must be removed. SCORES Score ID H12/BSC/16 Student Number Course Code 2745 BSC/202 EXAMS Course Name Total_marks BSC IT 75 Fourth Normal Form (4NF) This is aimed at removing multivalued dependencies, i.e., a table with independent attributes, but they both depend on another common attribute in the same table. To achieve this, all multiple independent relationships are isolated such that no table has multiple indirect 1:M or M: M relationships. In addition to this, no relation should have more than a single multivalued attribute (no non-trivial multivalued dependencies exist in any table). 4NF holds that despite a database satisfying the Boyce-Codd Normal Form (BCNF), it should exhibit no more than a single multivalued dependency. To get a 4NF from BCNF, get rid of all independently multivalued components and put them into two new ‘parent’ entities. For example, consider an employee with many skills and 7 several dependents. The skill and the dependent information repeat (are redundant) and independent of one another. Therefore, move them to separate tables. Fifth Normal Form (5NF) A table in 5NF minimizes redundancy by isolating all multiple relationships that are semantically related. For any table in the 5NF, all its non-trivial join dependencies are hint by candidate keys. However, some practical constraints may exist on information to justify the separation of logically related M: M relationships. For any table to be in the 3NF, it must satisfy these criteria: atomic data items, no transitive dependency, and all attributes to be depended on the Primary Key. For instance, the assignment table in the original ERD had violated the 3NF rules in that it was refencing two 8 distinct tables to acquire data, the products table and the employees’ table. This creates a functional dependency and thus the need to create a junction table (Assignee) to link both the Employees and the Products tables. Additionally, a to avoid redundant license IDs, the need for an individual licenses table arises. Moreover, in each table, the functionality of the attributes is depended on the table’s primary key. This new ERD also meets the 1NF since each table holds non-duplicated nuclear data elements. i.e., no attribute contains multiple values from each domain. This was achieved by breaking down the products table into two, purchases and products. The possibility of having two closely related columns in the same table is hereby eliminated. Any table in 2NF ought to be in 1NF and without non-prime attributes whose functionality is dependent on any candidate key in the relation. From our translated ERD, all tables conform to this. They all have atomic values as well as without non-prime attribute which depend on proper subsets of candidate keys. In conclusion, database normalization is a vital process in the design of DBMS as it forms the basis of redundancy removal, which will, in turn, come in handy in ensuring the efficiency and accuracy of the database. It, therefore, in our best interest to ensure normalization is undertaken to the very last step for better functionality of the DBMS. 9 References Eessaar, E. (2016).
