and proceed to
Certifications by product - List of certification product categorieshttp://www-03.ibm.com/certify/certs/index.shtml
and then to
IBM Information Managementhttp://www-03.ibm.com/certify/certs/dm_index.shtml
as far as the price is concerned why should we waste time researching? it' s not us who has to take the exam
and after all this is a technical help forum, not a shopping help one
this answer is meant to show how a bit of work on Your side would have got the same info which I just searched for You!
all was started with a simple google search for guess what ...
"IBM DB2 CERTIFICATION"
and the very first link returned was ...
IBM Professional Certification Program
Lay the groundwork for your personal journey to become a world-class resource to your customers, colleagues, and company through IBM Professional ...http://www.ibm.com/certify
how do You expect to pass any certification if you do not even have the basic skills of finding the info Yourself
or are You just lazy ???
