Learning Coverage

Learning Coverage

Though the PDS™ Kit is designed as a study and preparation resource for the online PDS™ Certification examination, the books, lab handbooks, and other learning aids included in the PDS™ kit have been put together to help aspiring Big Data Scientists build longer–lasting sets of skills and a more penetrative Big Data perspective. The PDS™ Kit contents therefore seek to develop in learners, a strong and complete generic, as well as platform–based understanding of the concepts, principles, tools, techniques, and technologies of designing, developing, and applying analytics frameworks and utilities required for sharper information management and decision making.

Indeed, while the Wiley–produced kit has been developed around the DASCA Essential Knowledge Framework (EKF™), the idea behind its design, coverage, content, and structure is also to provide to aspiring Big Data Scientists, a liberal exposure to all important proprietary analytics platforms currently in vogue in the Big Data space, and concurrently, they can prepare themselves rightly for the PDS™ Certification examinations, as well. The contents of the PDS™ Kit straddle all essential knowledge areas – divided up into eight sections or modules.
