Today's organizations are looking for more and better ways to pull out the information they need from the massive volume of data available to them. Big data system administrators store, manage and transfer large sets of data, making them amenable to analysis. Data analytics is the practice of examining the raw data to identify patterns and draw conclusions. Business intelligence involves the collection and organization of information to report on business activities, often pulling data from those very sets.

Along with the surge in big data interest has come a growing number of certifications, which seek to recognize the skills needed to work with enormous data sets. The target audience is IT professionals with a background in analytics, data mining, business intelligence or data management, along with a knack for and interest in mathematics and statistics. Big data engineers are in reasonably high demand and usually command salaries of $101,000 or more (according to Glassdoor), where data scientists average about $128,500 in salary.

MongoDB NoSQL Certifications

MongoDB is both an open source, NoSQL document-oriented database and the name of the company providing that technology. Because of its document-oriented NoSQL model, MongoDB is well-suited for managing large amounts of loosely structured data, as is so often the case in big data projects.

MongoDB was deemed a leader in Forrester Wave: Big Data NoSQL, Q3 2016, and Gartner selected MongoDB as a challenger in its 2016 Magic Quadrant for Operational Database Management Systems. The database ranks fifth in overall database engine popularity as of October 2017.

The MongoDB NoSQL certification program recognizes developers and operations professionals who can create and run applications on MongoDB. The program offers two associate-level credentials: MongoDB Certified DBA and MongoDB Certified Developer. The company plans to eventually roll out higher-level certifications. The current exams are based on MongoDB V3.4.

MongoDB offers private, instructor-led classroom training as well as free online video training through MongoDB University. Each online course typically runs for three to seven weeks and features video lectures, quizzes, weekly assignments and a final exam or project. Students may use the forums to interact and address each other's questions; instructors and teaching assistants monitor forums and jump in when needed.

For database professionals interested in venturing into big data projects and NoSQL databases, the MongoDB certification is certainly worth pursuing.

Oracle Business Intelligence Certification

Oracle has one of the largest certification programs in the world, and it has granted more than 1 million Oracle and Sun certifications.

Oracle's Business Intelligence (BI) certifications fall under the company's Java and Middleware certification track. The BI certifications are offered across several applications and platforms, such as Business Intelligence Applications 7 for CRM, Business Intelligence Applications 7 for ERP, and Business Intelligence Foundation 10 and 11g. To narrow down the field, we focused on the Oracle Business Intelligence Foundation Suite 11g Certified Implementation Specialist credential.

Candidates for this certification are intermediate-level professionals (architects, analysts, developers and administrators) who work with Oracle Business Intelligence Suite solutions, performing tasks such as installing, building, querying, configuring and managing the platform and BI dashboards.

Although anyone can attempt the exam, the certification is designed for members of the Oracle Partner Network who sell and deploy the technology.

The Oracle Business Intelligence Foundation 10 Certified Implementation Specialist is also available; it is based on a slightly older version of Business Intelligence Foundation but is still relevant in today's market.

SAS Certified Data Scientist

SAS is a multibillion-dollar global corporation that specializes in business analytics software and services. The company's well-honed certification program offers nine credentials across programming, information and data management, advanced analytics, and business intelligence.

Three noteworthy SAS certifications are the SAS Certified Data Scientist, SAS Certified Predictive Modeler Using SAS Enterprise Miner 13, SAS Certified Statistical Business Analyst Using SAS 9: Regression and Modeling, Business Intelligence Content Developer for SAS 9, and SAS Certified Big Data Professional Using SAS 9. We concentrated on the SAS Certified Data Scientist Using SAS 9.

Candidates for the Data Scientist certification should have deep knowledge of and skills in manipulating big data using SAS and open source tools, using complex machine learning models, making business recommendations, and deploying models. Candidates must pass five exams to earn the SAS Certified Data Scientist credential.

SAS doesn't require candidates to take certification courses as a prerequisite for exams, but the company offers an official curriculum for those who have the budget and need the extra preparation.

SAS "versioned" credentials, such as the SAS Certified Data Scientist Using SAS 9, do not expire. However, SAS may retire exams as new or enhanced software is released.

Beyond The Top 5: More Big Data Certifications

It was a real challenge to whittle down the list of popular big data certifications. The Cloudera Certified Professional Data Engineer (CCP Data Engineer) missed a top-five spot by a small margin. The company also offers CCA Spark and Hadoop Developer and CCA Data Analyst certifications. Given the company's leadership status in software and services based on Hadoop, the CCP Data Engineer certification is worth your time and consideration.

Other notable certifications include the IBM Big Data portfolio of certifications, the EMC: Data Science Associate (EMCDSA), and those from Amazon Web Services (AWS), Hortonworks, MapR and Teradata.

Check out Stanford's Data Mining and Applications graduate certificate. Although it's not a vendor-neutral or vendor-specific certification (it's a college certificate), TechExams.net forum members like it in terms of popularity and job prospects. The certificate requires completion of three courses (nine college units) at a cost of $11,340 to $12,600. The Microsoft Professional Program (MPP) currently offers four tracks for online education with course completion certificates, including two relevant tracks: one on data science, the other on big data. These are worth checking into as well, and significantly cheaper than the Stanford certificate program.

And there are many more. A quick Google search every month or two should reveal a growing list of big data, data analytics and BI certifications, and we think one or more of these is a smart way to spend your certification dollars.
