    What are the differences between big data and data science?

    Big data, as the name suggests, works with the enormous amounts of data, information and statistics that are gathered by companies. Such vast volumes of information are unable to be processed and understood using traditional data analysis methods, so big data has a way of comprehending and using this information.

    Big data deals with three key types of data, unstructured, semi-structured and structured. This covers a broad range of content such as information from social media, websites and images to XML and text files. Scientific methods are used to analyse and distil the information into a digestible format.

    Data science also looks at the same three types of data but uses a different approach. Covering data cleansing, preparation and analysis, data science uses a combination of skills including problem-solving, mathematics, programming and statistics.

    Data science applies a scientific approach to interpreting the data using algorithms and machine learning to find disguised patterns among raw data. Data science intersects the data and computing sectors. To help distinguish the two fields further, data scientists work within an area of big data.

    What are the differences between a big data and a data science career?

    When it comes to discerning one from the other in relation to pursuing a career path, one is focussed on obtaining data to generate greater efficiencies and enhancing competitiveness. In contrast, the other is concentrated on modelling techniques that evaluate the big data.

    Working in big data could lead to a career in finance, retail or communications. However, it’s all about working behind the scenes for these sectors, collating information that can change how the businesses operate. Whether it’s using data to find a competitive advantage or identify untapped opportunities, big data is fundamental to the expansion, growth and development of businesses.

    Data science, on the other hand, could lead to a career working across sectors including internet search engines, digital advertising or recommendation services. Data science takes information that big data has sourced and analyses it to make better business decisions. Data science careers are about delivering results through the application of learnings from big data.

    What would be better suited for me?

    Now that we’ve examined a few ways that data science and big data are applied to careers, you might be wondering how to decide which is best suited for you.
