With more companies worldwide set to invest in big data, the demand for qualified professionals in data-related fields is projected to grow, which, in turn, is expected to drive salary growth.

The technology research company Gartner Inc. reported in September 2015 that more than three-quarters of firms are investing or plan to invest in big data through at least 2017. That represents a slight increase over the percentage of companies that reported investment plans in 2014.

Nearly two-thirds of the companies responding to the new Gartner survey listed “enhanced customer experience” as the No. 1 goal of their big data initiatives, with “process efficiency” and “more-targeted marketing” each listed by 47% of firms.

Gartner previously reported that nearly 2 million jobs in Information Technology would be created nationwide between 2012 and 2015 to support the growing role of big data in the business world.

Big data, along with security and mobile technology, will be a major factor fueling employment opportunities in IT during 2016, including for database administrators, according to a report by the global staffing firm Robert Half.

“More companies are using big data analytics to help inform business decisions and are relying on specialized personnel for managing and interpreting raw data,” Robert Half reported in September 2015, adding that starting salaries for IT professionals are projected to rise by 5.3% on average in the next year.

The data-related careers highlighted in this guide typically require candidates to have strong analytical, problem-solving and organizational skills. Many of the positions also require superior verbal and written communication, as well as a high level of creativity.

A thorough understanding of relational database theory and practice may be essential, along with experience in enterprise database programs such as Microsoft SQL Server, Oracle or IBM DB2. In addition, employers often require experience in specific programming languages, including Java and SQL.

A bachelor’s degree in Computer Information Systems or a related field may be required for entry-level positions. Advancement to managerial and analyst positions may be possible with additional experience and an advanced degree such as a Master of Business Administration with a concentration in Cybersecurity or an MBA with a concentration in Information Technology Management.
