Business leaders and top executives keep talking about big data.  Job applicants put the word ‘big data’ on their resume.   To put things in perspective, big data is to the business world what ripped jeans is to teenagers.

However, big data is not just a passing trend.  It is an important part of business operations, sales, marketing, business management and every aspect of business.

Read on to find out what is big data, and what a big data course is all about. You will realise why you should enroll for one.

What is Big Data?

On a day-to-day basis, as different functions take place in a business, data gets generated. For example, if you look at an app, data would be generated around how many times each button on an app was clicked, how many times it led to another button getting clicked, which button got clicked, what happened after that, and so on and so forth.  Over a period of time data piles up into large volumes, and such large volumes of data is called big data.

Big data is characterised by volume, velocity and variety.  That is to say, large volumes of data get generated at a high speed as various functions take place through the day.  Apart from volume and velocity, big data also comes in all shapes and sizes, and it can be either structured or unstructured.

Big data helps us find out the root cause of problems, or automate solutions and functions.  For example, an automated program can sort which employee should be given the “Employee of the Month” award based on their performance data from project management tools and attendance or punctuality data from automated tools.

It is not possible to manage big data manually because of the volume, velocity and variety. There are tools to tame big data and make it manageable for further computing such as preparing automated charts and graphs for the end user stakeholders, or other as the case may be.
