Purdue University The Identified Entities for Conceptual Data Model Database Task

Purdue University The Identified Entities for Conceptual Data Model Database Task

Question Description

I’m working on a computer science multi-part question and need support to help me understand better.

Given a Movies Dataset, you will conceptualize a database solution using three or more tables. Based on the data analysis, you will then create a conceptual model using Microsoft® Visio®

  1. Download and use the Movies Dataset attached for your analysis.
  2. Identify the entities for the conceptual data model, and then determine which entities are related.
  3. In your Microsoft Word report, write a list of the entities, and explain your choices. In this same document, describe the relationships that exist between these entities, and using a few sentences, explain why they are related.
  4. In Visio (or within the same Word document), create a conceptual database model that shows the entities and their relationship. Refer to the Module 1 learning activity for an example.
  5. If you created the conceptual model in Visio, embed the Visio diagram in the Word document so that you have a single document for submission.

Part 2 – Logical Data Model

Continue to normalize the design and create a logical model using the conceptual data model created in Part 1 and leveraging the same Movies Dataset.

In a Word document, write the following:

  1. For each of the entities, define all of the attributes. Define the data type and nullability of each attribute. Explain your choices.
  2. For each of the entities, define the primary key. Define the data type and nullability. Explain your choices.
  3. For each of the entities, define any foreign keys. Define the data type and nullability of each key. Explain your choices.
  4. Create a logical model diagram using Microsoft Visio. Refer to the learning activity for an example. Please embed the Visio diagram in your Microsoft Word report so that you are only submitting a single document for this assessment.

Task 2 – Establish Data Models Based on a Medical Form

You will undertake a design process for a new scenario associated with building a new patient database. You will use a provided medical data form to collect medical information that may be used by a doctor’s office as the basis for creation of diagrams representing the conceptual and logical models of the database.

Part 1 – Design Management

Assume that this task involved a group of database designers, and you served as the group lead. Describe how you and your team would undertake the conceptual and logical database designs. How would you manage the group efforts? What means would you use to communicate with the team? How frequent should the team communicate with each other? How would you go about integrating the work accomplished by the individual team members?

Part 2 – Conceptual Data Model

Given a Medical Data Form, you will conceptualize a database solution using two or more tables. Based on the data analysis, you will then create a conceptual model using Microsoft® Visio®

  1. Download and use the Medical Data Form attached for your analysis.
  2. Identify the entities for the conceptual data model, and then determine which entities are related.
  3. In your Microsoft Word report, write a list of the entities, and explain your choices.In this same document, describe the relationships that exist between these entities, and using a few sentences, explain why they are related.
  4. In Visio (or within the same Word document), create a conceptual database model that shows the entities and their relationship. Refer to the Module 1 learning activity for an example.
  5. If you created the conceptual model in Visio, embed the Visio diagram in the Word document so that you have a single document for submission.

Part 3 – Logical Data Model

Continue to normalize the design and create a logical model using the conceptual data model created in Part 2 and leveraging the same Medical Data Form.

In a Word document, write the following:

  1. For each of the entities, define all of the attributes. Define the data type and nullability of each attribute. Explain your choices.
  2. For each of the entities, define the primary key. Define the data type and nullability. Explain your choices.
  3. For each of the entities, define any foreign keys. Define the data type and nullability of each key. Explain your choices.
  4. Create a logical model diagram using Microsoft Visio. Refer to the learning activity for an example. Please embed the Visio diagram in your Microsoft Word report so that you are only submitting a single document for this assessment.

What sources did you refer to while working on both tasks of the assessment? Cite these sources within the body of the paper and annotate those as your references at the end of the paper.

Be sure your work demonstrates the ability to apply critical thinking skills to illustrate sound reasoning. This includes the ability to identify entities, formulate inferences and identify relationships between entities, identify faulty reasoning, assess assumptions, formulate conclusions, and assess what you referred to while you worked on in this assessment.
