CS 346 Database Management Systems
Spring 2022
Final Project
A company is planning to create a database for the expense reports submitted by employees from
various departments within the company. Each department has many employees and each employee
belongs to one department only. Each department has a department manager who can manage one
department only. When an employee spends money for business purposes, they submit an expense
report with the details of the items they spent money for. Each expense report is submitted by one
employee only. An employee may submit more than one expense report. There are employees who
never submit any expense reports. Each expense report contains one or more expense items. The
company maintains a list of all the expense items that could be reimbursed. Each item in this list may be
included in more than one expense report. Some items may exist in the list even if they have never been
included in any expense report yet. Expense items are grouped into categories. Each expense item
belongs to one category only and each category contains many items. A sample report with expense
reports submitted by employees from three departments is attached.
Given the information mentioned above and the attached report, design and implement the database
that will be used for the automated Expense Report System. To achieve your goal, complete the
following tasks:
1 Identify all the entities that will be captured in the database. Submit a list of these entities.
2 Analyze the information provided to extract the business rules that will be used to drive the
design of the database. Submit a list of the business rules.
3 Draw the (ERD) for the database using the Crows Foot Notation.
4 Review the data in the attached report to identify all the data elements of the database.
5 Use the data in the report and follow the normalization steps discussed in class to group the
data items into tables normalized to the 4NF.
6 Optimize the 4NF database by introducing any necessary surrogate keys that will improve the
overall database design.
7 Submit a list of the 4NF tables and the attributes in each table. Indicate the Primary Key for
each table as wel las any Foreign Keys that might exist in the table.
8 Revise your Entity Relationship Diagram to see if any updates are needed after the
normalization and optimization steps. Submit your final Entity Relationship Diagram.
9 Create the database with all the tables in the . Submit your MS SQL Server
Database File (YourLastName_DB.mdf).
