Business Case and Example are attached
Overview
Entity relationship diagrams (ERDs) represent the data portion of a
cloud-based database. This is why ERDs are often used as a tool to
communicate how information is stored in a database. Being able to
describe what goes into a specific database (entities, attributes, and
relationships) ensures that you end up creating a cloud database that
actually supports organizational operations. You want to avoid creating a
database that stores irrelevant data.
For the purposes of this assignment, imagine that you are a solutions
architect at a start-up organization, Your Online Database Architecture
for Education (YODAE). To provide some context, YODAE is an educational
technology company that is quickly growing and scaling its services.
Its cloud solutions are used by teachers, educators, and administrators
in the K–12 education industry. In order to implement a cloud-based
system that meets YODAE’s clients’ needs (in this case, schools), you
will design the cloud database.
Prompt
For this activity, you will create an ERD that will represent
student-information and teacher-information data. To successfully
complete this activity, you will need to:
Review the YODAE Business Case:
Review the business case document to gain a better understanding of
YODAE, and of how your cloud solution will meet its organizational needs
and operations.
Create an Entity Relationship Diagram: As part of
the design of the cloud-based database, create an ERD to show the
architecture of the cloud database system. To create your ERD, refer to this example that already includes some components of your diagram. You must add to this diagram by including the following components:
All of the appropriate entities: What are the entities that need to be included in the ERD that are described in the business scenario?
All of the appropriate attributes: What are at least five attributes for each entity?
Necessary relationships: How will the relationships between the entities be accurately presented in the diagram?
Explain Your ERD: Write 2 to 5 paragraphs about how
your diagram meets the needs of YODAE and its clients. You are required
to provide a brief explanation about the entities, attributes, and
relationships depicted in your diagram.
What to Submit
Upload a file that contains your ERD. You may use Lucidchart, Visio,
or another software application of your choice to create your diagram.
The file you upload should either be in a .doc or .pdf format. Do not
submit the Lucidchart or Visio file that you created. Select All of the
elements of the ERD from within the application you used to create it,
and copy and paste into a Word or PDF document prior to submitting it
for assessment.
