I am in the market for some quick, effective training in Oracle Development focused on consumption from a ASP.NET development point of view.  I don't need to know how to admin the Oracle server, just how to write effective, efficient queries, setup performant data models, optimize data access and fix our overabundance of foreign keys, indexes and CLOBs.  I am advanced in SQL Server development, but need to know the nuances that differ in Oracle.

Any recommendations?  Thanks in advance!
