What is big data?

Big data refers to sets of data that are too large and complex to be analysed using traditional methods. The concept of big data was first articulated by Doug Laney, a data analyst for Gartner. 

In his 2001 report, Laney argued that the growth of ecommerce and other forms of digital activity meant that businesses would need to look at data storage and analysis in a new way. Laney defined big data as data which was high in volume, velocity and variety.

In the digital age, businesses collect huge volumes of unstructured data from a range of sources. Vast swathes of new data stream into businesses faster than ever before. The types and formats of big data vary hugely and are less structured than traditional data. 

Storing, analysis and utilising big data effectively represented a new business challenge, Laney claimed. And businesses that conquered this new data frontier would be at a huge advantage when it came to making data-driven decisions. 

The power of data-driven decisions

The power of big data is unleashed when it is combined with data analysis. Analysing huge volumes of data can uncover unique insights. These insights can inform business decisions and improve results. 

For example, ecommerce data can help retail brands to identify buying habits. This can help inform the creation of new products. And marketers can use these insights to optimise their campaigns and increase sales. 

As well as driving innovation and informing marketing, insights from big data can also reduce fraud, improve operational efficiency, and enhance customer experience. 

Data driven decision making enables businesses to increase efficiencies and boost profits. Strategies that are based on verified data, rather than educated guesses and gut feelings, lead to more successful outcomes. 

Careers in big data

Businesses are crying out for data scientists with the skills and qualifications to work safely and securely with big data. 

Data science is at #3 on LinkedIn’s Emerging Jobs Report 2020, with a 37% annual growth on 2019. Without analysts to unlock the value of big data by spotting patterns and uncovering insights, companies are unable to benefit from data driven decision making. 

You can expect an average entry level salary of around £26,000. Once you gain experience in the role, the salaries continue to increase with the average salary within the profession as a whole being beyond £56,000.

But what sorts of roles are available in big data and what do they involve? Let’s explore:

Database administrator

Database administrators organise and store big data using specialist software. They ensure that data is consistent, clearly defined and secure. Without the crucial work of database administrators, data analysts and scientists wouldn’t have trusted data sets to work with. 

Data analyst

Data analysts use analytical skills to spot patterns and draw insights from big data. They produce business critical reports that help decision makers shape business strategy. A good analyst is able to tell a story with data, translating complex data into easy to understand trends.

Big data developer

Big data developers using coding skills to develop data storage solutions like Hadoop that make working with big data possible. Developers working in big data will need knowledge of Java, SQL, and other scripting languages to create and maintain these systems.

Data scientist

Data scientists use their analytical and problem solving skills to guide a business towards profitable opportunities. Using data analysis and interpretation to solve business problems, data scientists identify new ways to make and save money.

I was also worried that my age and lack of relevant experience would count against me once I’d gained the qualification and was actively seeking work. Stuart was able to allay any fears that I had, but did so without making any grand claims or false promises.”
