DAT 390 Week 1 Apply U.S. Student Aid Initial Database Schema
You are assigned a project to evaluate higher education student aid data
from the U.S. government to answer the following questions:
• Which schools generate the highest amount of debt for the
average student who attends?
• What is the employment rate for the students who graduate from
this school?

3. You will complete this cumulative project throughout the course This
week, you will complete an initial review of the data and prepare an
initial database schema and data discrepancy recommendation.
Download the following spreadsheets or CSV files:
• School Code List (this link is not working for some reason but
luckily I have this file from a recent previous class):
2021FedSchoolCodeList.xlsx
• Most current spreadsheets for Loan Volume, Grant Volume, and
Campus-Based Volume

4. • Gainful Employment Information
Develop a database schema diagram based on the data tables you
downloaded. Use Microsoft® Visio® to display your diagram. Your
diagram should include:
• The identification of metadata that needs to be included in each
table
• Annotation of the diagram to identify where there may be
schematic discrepancies between the data sources
Summarize your recommendations for resolving anticipated
discrepancies and identify which strategy you would use to validate the
data quality in a Microsoft® Word document.

5. Note: You will use the downloaded files and your drafted schema in the
Week 2 individual assignment, U.S. Student Aid Database Schema and
Query Recommendations.
Submit your Microsoft® Visio® file and Word® file.

DAT 390 Week 2 Apply U.S. Student Aid Initial Database Schema and
Query Recommendations
This week you will continue your work on the project to evaluate higher
education student aid data. You will test your recommended U.S.
Student Aid database schema, build the database, and develop the
business intelligence queries that will enable you to answer the
following questions:

6. • Which schools generate the highest amount of debt for the
average student who attends?
• What is the employment rate for the students who graduate from
this school?
Revise the schema you submitted in Week 1 per your instructor’s
feedback.
Test your schema by completing the following tasks:
• Define the database tables you will need and group the tables by
function. Document your tables in an annotated Microsoft® Visio®
diagram.
• Develop the SQL queries needed and populate the tables from
the data downloaded for your Week 1 assignment. Your assignment
should:

7. • Define an appropriate strategy to optimize and incorporate best
practices in to the SQL that you created.
• Document your SQL and metadata in Microsoft® Visio® or
Microsoft® Excel®.
• Capture screenshots of each query result.
Note: You may "mock" up the SQL statement and query results if you
do not want to download a database.
Document your results as a 1-page Microsoft®Word document that:
• Describe your SQL, populated tables, and the best practices you
used to develop your SQL queries

8. • Include the SQL statements and corresponding screenshots of
each query result
Compress your revised diagram(s), testing results documentation, and
.SQL files into a ZIP folder.
Submit your assignment.

9. This week you will continue your work on the project to evaluate higher
education student aid data. You will transform your operational data
structure and schema into a data structure and schema for a data
warehouse, which will be exclusively used for reporting.
Develop a plan to integrate this new data warehouse with an internet
application. Include in your plan:
• A description of the transformation process
• A schema diagram identifying the changes needed
• Revise the diagram you submitted in Week 2 per your
instructor’s feedback.
• Specific integration plans
Document your plan as either:

10. • A 1- to 2-page Microsoft® Word document
• A 6- to 7-slide Microsoft® PowerPoint® presentation with
detailed speaker notes
Note: It is recommended that you select the delivery method of a
Microsoft® PowerPoint® presentation or a Microsoft® Word document
to use consistently throughout your weekly assignments.
Compress your revised diagram and your plan into a ZIP folder.
Submit your assignment.

quality of data they can expect from the new data warehouse.

12. Include the following information in your summary:
• Your data evaluation strategy
• Specific data evaluation queries
• Sample results per query
• Summary of findings
Document your summary as either:
• A 10-slide Microsoft® PowerPoint® presentation with detailed
speaker notes
• A 2-page Microsoft® Word document
