Data Mart and Schema

The following only provides some preliminary and partial description of the scenario. It's enough to get your started to understand the type of data and the analysis we want to see from data. But you need to exercise your analysis and design skills to understand more. This is critical in any data modeling and design.

Be like an analyst and inquire more!

Data explanation

1.      CRN is course section offering id, and should be unique across semesters (80% sure)

2.      Course section: 9xx - online, 8xx - hybrid, 0xx - in-classroom

3.      Course number: 1xxx-4xxx (undergraduate, 1 to 4 for freshman, sophomore, junior, and senior), 5xxx and above (graduate)

4.      CCSE courses have five prefixes: IT, CS, SWE, CGDD, CSE

5.      The last column are the three types of enrollment headcounts:

actual enrollment number/initial enrollment number/max available seats

Sample queries and analysis

1.     We want to focus on CCSE the college as well as the IT department.

2.     Class registration analysis: providing a view of registration head counts from different perspectives.

a.      Total registration head counts as a whole, and by department and class level (graduate or undergraduate).

b.     Registration history (all semesters in the database) of key courses.

c.      Data in current semester compared to those in the same semester of last year.

d.     Online course registration trend (by computing subjects like IT, CS, Security, etc.).

e.      Other metrics like withdraw rate, average class size, class room utilization etc.

f.       [Challenge] Prediction of class enrollment and number/type of sections offering

3.     Degree program analysis

a.      Growth as a whole or in certain aspects like MSIT

b.     Comparison of departments in areas like course number, class size, faculty work load, trend, etc.

4.     Faculty performance and workload. Some key analysis include:

a.      Individual faculty member's most recent academic year.

                                                             i.     Total number of courses, and by semester

                                                           ii.     Total number of sections, and by semester

                                                         iii.     Total registration head counts, and by semester and course

                                                         iv.     Withdraw rate for each course section

b.     Faculty as a whole group

                                                             i.     Registration head count total by employment status (full time or part time), rank (professor, associate prof, lecturer, etc.), and by department

                                                           ii.     Number of course sections total by employment status, and by department

In this first milestone, we will:

·        Analyze the sample data-set and understand the relevant business (terms, rules, data, etc.)

·        Design a reasonable star schema to model the data

·        Implement the star schema in SQL Server and design dimensional data mart structure

Requirements

1.     Analyze the sample business requirement and class registration data provided. Reasonably expand the scope of the data to consider additional data that might be beneficial, like all departments, past semesters, or faculty information. The project is designed as exploratory and open. You will have questions and you need to ask questions to find out details.

2.    Design star schema for this data based on your analysis of the requirements and understanding of the domain. They must be reasonable and justifiable. Clearly show major measures, dimensions and their attributes. Use any software program to do the modeling.

3.     Design a data mart based on the star schema using SQL Server Database Engine. Schema/data mart requirements (may or may not align with your design; but for consistency please meet the following minimum requirements).

o  The fact table should include at least three measures: actual enrollment (the first number of the last column), original enrollment, maximum seats.

o  Please design at least four dimension tables.

o  Make use to have primary keys, relationships (foreign keys), appropriate data type/length, and other constraints.

4.     Design a SQL Server database diagram and take a screenshot of the diagram.

Submission

Compile all required documents and screenshots in ONE PDF file and submit it in D2L. All screenshots must be clear, original, and show the complete screen - no graphic editing or cropping is allowed. Clearly label and explain all parts.

1.      A screenshot (or an image) of the star schema (logical design) you designed using a modeling tool like ERDplus.com.

2.     A screenshot of the SQL Server data mart (database) diagram. Make sure all column data types and keys are shown in the diagram (choose the standard view).
