This assignment uses the same case study that you used in assignment one. We have provided you with the following extra details (from the LMS):
In groups of 2, you are required to carry out the ETL process to get the data from these source tables into the data warehouse that you designed. You will design 1 transformation per fact or dimension table in the data warehouse. You are then asked to write a report about the process (see requirements below).
This assignment is worth 25% of your assessment for the subject. Historically, the average mark for this assignment has been around 17/25 marks.
You will write a 2000 word report outlining the main issues and concerns you came across in performing the data load. A suggested outline for the sections of the report is (Please note that this structure is a guide only and can be changed if you wish, word limits are suggestions):
1. Executive summary: An executive summary is a short summary of the key information in the document and is written for a business person. It should contain clear details in summary form of the issues you came across in designing the ETL process. (200 words)
2. Design of the ETL Process: You should discuss and justify the design of your ETL processes.
Include diagrams of the design of your ETL transformations (for each fact and dimension table in your data warehouse) to use as evidence for the discussion. (1200 words)
3. Design of the Data Warehouse: If you had to do some redesign work on your data warehouse, detail what you changed and give reasons for the changes. (300 words)
4. Data Dictionary: Describe the types of additional meta-data that would be required in the Data Dictionary that you developed in Assignment 1, based on the ETL process. You should list and describe the kinds of metadata you need to store in a data dictionary in addition to what was required for assignment 1 – do not simply reproduce the assignment 1 data dictionary (300 words). NOTE: we are not asking for a complete data dictionary here – we are just asking for the TYPES OF ADDITIONAL Meta Data required (see the meta data lecture).
5. Appendix 1 – Work Breakdown: Detail the breakdown of work of the team members for this assignment. This should be a detailed account of what each team member accomplished as part of the assignment. Assessment Criteria
