Anyone took this exam? Review?

Found CIW | Database Design Specialists Design and Optimize Relational Databases "CIW Database Design Specialist"

1D0-541 exam objectives: http://www.ciwcertified.com/_resourc...es/1D0_541.pdf
1D0-541 course contents: http://www.ciwcertified.com/proddesc...EDBDMPR802.PDF

It seems to me it's more entry level than "1Z0-047 Oracle Database SQL Expert". That means simpler. Do you recommend me 1D0-541 as first step?
