We have Eric's request about set with the data warehouse. Bruce is trying to adjust the report in Cognos to show the way that Eric would like. I need to go through and really polish the ETL for the whole data warehouse:

1. Add in some of the transformations to the ETL (Some of them were done on the fly for testing)
2. Redo student to enrollment, so it has the lowest level of detail?
3. Add a mapping in student/enrollment for the one that we deleted. (to not load 2 things in one mapping)
4. Possibly rename some things and have a better process for ETL development
       a. When to bind dimensions/cubes
       b. When to deploy, just to see if there is a faster way.
5. Build easier to get to data (if student/enrollment is redone)
6. Revisit the demographic for student.
7. Revisit the academics for student.

I have also been setting up some cron jobs on wouupg and getting up to speed with what needs to be done.

Data Warehouse

This week we have been working on answering Eric's question with the data warehouse. I feel like the planning made before hand was good but I can now see where it can  be polished a little more:

1) First thing is ALWAYS add time to research and understand how to answer the question in production   and how things are linked. When we planned this, we just thought of the work to make the dimensional model.

2) Time to Build and load ETL + time to link in Framework Manager + time to make reports + research time + testing time = total time. Keep in mind while testing, this might mean going back through the whole process (hopefully not, but it happens).

While doing this I was able to squeeze in fixing the leave in production. Banner figures leave a little different than how we used to figure leave so we are going to match  how Banner works with leave rather than the other way.
