Since the internet went public in 1995, there’s been an explosion in data creation. In 2013, there were 4.4 zettabytes of data in the world and this is expected to increase tenfold by 2020. To put this into perspective, a zetta equals 1021, a number so large it defies human imagination. And this figure is only growing exponentially, fueling a global demand for people with strong skills in data analytics.
Of course there’s a fine line between having too much and too little data. Too few hard numbers may require an organization to make guesses or assumptions. There are occasions when a “go with the gut” leap of faith can be useful and rewarding, especially if part of a company’s culture and vision is to be innovative and daring. But in other instances, trying to answer a question such as “What do our customers really want?” without having solid, reliable information can be troublesome, especially if the only evidence you have are a handful of personal anecdotes or online comments.
Too much data can cause opposite problem. Besides making Powerpoint presentations infinitely drier, too many numbers and statistics can be overpowering, almost to the point of paralysis.
Ultimately, a quantitative overabundance can become too big to manage, bogging down the decision-making process.
So where is that sweet spot that can easily provide just the right amounts and types of data to help objectively guide a company in its decision-making process? People who can answer this question may become superstars in the workplace, building databases, rebuilding legacies, and providing insights on demand, including projections for a company’s future budget, operations, and sales targets by identifying appropriate associations, trends, and patterns.
Certainly, companies have had access to different sources of information, such as sales trends and various government reports about domestic production or payroll, but until recently, the typical company didn’t always have time or resources to mine too deeply. Today’s world of Big Data is different, with fast and easy access to shared databases in the cloud; database software with better searchability; site tools, extensions, and plugins that gather the tidbits of info; and more courses to teach people useful skills and processes.
It’s not surprising that the Big Data profession—a group which includes various analysts, scientists, engineers, and administrators—is expected to see 700,000 fresh openings by 2020.
Furthermore, the Bureau of Labor Statistics (May 2016) reported that the mean salary for database administrators was $87,130.
Even for non-quants, learning how to interpret and manage figures can prove very beneficial across industries. Learn why skills in data analytics are expected to be valuable and how to develop knowledge in this field.
Mastering data analytic skills can open doors into a variety of industries and help professionals remain valuable to current employers. Virtually all industries can benefit from trained data experts, including engineering, architecture, pharmacology, manufacturing, and healthcare, among others. But, according to IBM, the heaviest demand—59 percent of all jobs in this field—is going to be in finance, insurance, professional services, and IT companies.
The highest regions of demand for skills in data analytics are financial, high-tech, and political metropolitan communities with large populations, including New York (eight times higher demand than average); San Francisco/San Jose (22 percent higher demand than average); and Washington, D.C. (14 percent higher). Los Angeles, Dallas, Boston, Atlanta, and Philadelphia are also considered to be rapidly growing for this sector as well. Plus, due to lucrative salaries offered, it might be easier to survive in some of these communities with higher costs of living.
People with database knowledge combined with other skills can be seen as even more assets to an organization, including software engineering; programming (e.g., SQL, Python, Apache Hadoop, SAS, Java); communication; business ethics; and even machine learning, where people can teach computers how to follow instructions and recognize patterns. This type of automation can save time and produce useful results.
