The steps for the "Create multi-source VDB" are confusing. Here are the steps:
1) Create a Teiid Model project
2) Model tables from a flat file data source
3) Model tables from a JDBC data source
4) Create joined view of data sources
5) Create and test your VDB

Problems:

• I dont think Step #2 is needed at all. Step #3 contains steps for modeling the flat file.
• Same with Step #4 - not needed? Step #3 contains steps for creating the views.
• Upon looking at this closer, I think the intent was to break Step #3 apart. That is probably the right solution - pull some items out of #3 into #2 and #4...
