Task Summary
This assessment requires you to prepare a modelling report that demonstrates your ability to assess business requirements along with a logical design that could be implemented in a relational database management system.
Context
When preparing to implement a new information system, it is essential that the initial design is well thought out from the outset. Modifying the database after implementation can often be an expensive process in terms of time, effort and cost. Often the first engagement step is to conduct interviews and workshops with end users and business subject matter experts to get a better understand of how the business runs. The output of these workshops becomes the foundation for the database design.
Task Instructions
1. Please read the attached MIS602_Assessment 1_Case Study.
2. Based on the information provided in the case study, prepare a modelling report to answer the following questions:
• An entity relationship diagram including significant attributes against each entity.
• A relational model showing all fields, primary keys, foreign keys and concatenated keys. Your relational model should be in third normal form. List any assumptions/business rules you have made.
• A sample screen of what you think your online order form might look like. You may use any tool you like to create this sample screen. Write a brief paragraph discussing the following:
o Does your database design allow the storage of all the required information?
o What changes, if any, did you make to your initial ER diagram and relational model after you created the sample input screen?

Entity relationship diagram
The ER diagram does not have to be in 3NF. i.e. it can contain many
to many relationships
40%
Only a few entities identified and labelled. No relationships identified. Most entities identified and labelled. Most relationships identified. All entities identified and labelled.
All relationships identified.
Most cardinality is correct. Most Participation is correct. All Relationships meaningfully labelled. Primary key labelled for entities.
All cardinality is correct.
All participation is correct. Primary keys labelled for
many-to-many relationships. Some non-key fields labelled.
Overall, a well-presented entity relationship diagram.
Relational model
The relational model needs to be in
3NF and free from anomalies
40%
Only a few entities converted to tables. Design is not in third normal form.
No list of assumptions/ business rules. Most entities converted to tables. Most fields listed. Design is in third normal form. List of assumptions/business rules provided.
All entities converted to tables. All fields listed.
Most many-to-many relationships deconstructed into new tables. Primary keys correctly underlined. All many-to-many relationships deconstructed into new tables. Foreign key correctly underlined. Any multi-valued attributes deconstructed into new tables. Any selfjoins identified. A wellpresented relational model.
Sample screen
Sample screen of the online order form.
Discuss how the database design allow the storage of all the required information and the changes made to the initial ER
diagram and relational model
20% Sample screen does not capture the requirements of the order.
No discussion paragraph provided. Screen captures most of the requirements for the order.
Discussion paragraph does not address the key points. Screen captures all of the requirements for the order. Discussion paragraph is provided. All screen fields correctly mapped to a field in the relational model. Discussion paragraph is well written and addresses the key points.
All screen fields correctly and accurately map to a field in the relational model.
Well-presented sample screen along with a discussion paragraph that addresses the key points with clarity and detail.
