There are a number of sources you can get help from (Teradata manuals, online reference, various books and also instructr led courses). Please be aware though, certification means very little without experience.
it seems that they (Teradata) have stopped doing so (distributing jackets). I have the master certificate hanging on my wall (meaning they sent me all the stuff as with the previous exams), but I have not received any e-mail from Teradata.
either they just forgot you (mazorro) or they have brought it back to life in the meantime. As a newcomer among the Teradata Masters, I've got a message, just as described above, and been asked about my size as well as my preferred shipping address. This was even before the invitation to the Master's Forum/Mailing List I haven't received so far.
I have received a mail from Jacqueline.Schierer@teradata.com for Master jacket after completing all the 6 Certifications and as per my request for size its been delivered at free of cost, The effort for completing 6 certification is equilant to one Teradata Master Jacket and own values. even you will feel the excellency.
