515 Assignment 6 SQL Concepts and Database Design
The Strayer Oracle Server may be
used to test and compile the SQL Queries developed for this assignment. Your
instructor will provide you with login credentials to a Strayer University
maintained Oracle server.
Imagine that you work for a finance
industry-based organization. Your organization is looking to submit its
database design documentation to an evaluation team in order to meet
Sarbanes-Oxley (SOX) compliance. You have been assigned to assist in preparing
the documentation of the organization’s sales database. You are asked to
propose a data dictionary that can be used to document the following:
- Employee (EmpNumber, EmpFirstName, EmpLastName,
CommissionRate, YrlySalary, DepartmentID, JobID)
- Invoice (InvNumber, InvDate, EmpNumber,
InvAmount, CustomerID)
- InvoiceLine (InvLineNumber, InvNumber,
ProductNumber, Quantity)
- Product (ProductNumber, ProductDescription,
ProductCost)
- Department (DepartmentID, DepartmentDescription)
- Job (JobID, JobDescription)
- Customer (CustomerID, CustomerName,
CustomerAddress, CustomerPhone)
Write a three to four (3-4) page
paper in which you:
- Create a data dictionary that includes the following:
- A description of the content for each field
- The data type of each field
- The format the data will be stored as in the field
- The range of value for the field
- A label, as required, if the attribute is a primary
key or foreign key
Note: An example is shown in Table
7.3 in chapter 7 of the textbook.
- Imagine that you are asked to identify the number of
days that exist between the first invoice and last invoice for each month
and complete the following:
- Construct a query that will show the number of days
that exist between the first invoice and last invoice, for each month,
for each employee, using the DATEDIFF function. Be sure to provide the
SQL script that will carry out this function.
- Construct a query to show the expected payment date if
invoices are due within 30 days of transaction.
- Construct a query that will show distinct area codes
of the customers.
- Create a plan of the necessary activities that would be
required to implement a valid database design process by including the
following:
- Steps in the conceptual design stage
- Steps in DBMS selection stage
- Steps in logical design stage
- Steps in physical design stage
- Task details of each activity within each stage
