I'm new to Data Warehousing and a fresher. I've a plan to take an Oracle certification followed by a Teradata professional certification.
So, looking forward, whether I should take 'Oracle certified Associate' or 'Teradata certified Professional' certification first... and the value of Oracle Certifications in near future..
I would say it depends on the EDW strategy of the companies / projects you will work for. For full EDW implementations then the Teradata certification is a great asset as Big Data analytics, full enterprise consolidation and heavy-load BI applications run best on Teradata systems (which will probably be the best option). For small-scale data-marts and databases some companies go for other DB systems first before they decide to move forward to the Teradata analytical platforms. In this case, it might be reasonable to get certifications in the system you will work with first then delay the Teradata Certification until it is needed for EDW projects.
