Business Intelligence
You have been hired as a consultant for a small retail company that sells widgets online. The 
company is interested in learning how to use their data to improve their business. They have asked 
you to write a business case (search term business case template) to explain the justification for 
implementing a database management system to improve business intelligence within the company.
Within your business case, begin by explaining business intelligence. Then explain data 
management and how a database management system can facilitate business intelligence. You 
should also explain the benefits that the company will experience with the system. 
Next, consider the design of the system. Begin by describing the data entities, attributes and keys. 
For instance, a data entity may be Customer. Attributes of customer may include name and 
address. The key may be a uniquely assigned customer number. You should have at least five data 
entities in your database. Create an entity-relationship diagram showing the relationship between the 
entities (YouTube search term: entity relationship diagram tutorial). Create a relational database 
model to describe the data (YouTube search term: relational database model). ( I have added an attachment of what I turned into the teacher and my grade was 0/100.
