Over the years, the data output has seen unprecedented growth. This is driven by the rising percentage of mobile users, the influx of internet access, and a boom of eCommerce apps. Businesses rely on data science approaches to collect, analyse, model and analyse data in response to this data stream. This enables them to make informed decisions, drive revenue growth and succeed.
What is Data Science?
Data science explores big data. It also employs scientific processes, methods, and algorithms to extract valuable insights and business intelligence from the diverse structured and unstructured data. It encompasses the realms of machine learning and enables the discovery of meaningful patterns and knowledge.
The data science journey follows a comprehensive workflow that involves several intricate processes. It all begins with data acquisition, where diverse data sources are gathered and aggregated. It's like placing every piece of the puzzle in a box so they can be readily located and studied. Of course, before we begin the analysis, we must ensure that the data is trustworthy and accurate.
After the data is collected, you can follow it up with data warehousing. This means organising and storing the data so that it facilitates efficient retrieval and analysis. It's like fitting all the puzzle pieces in a box so you can easily find and examine each one. We also need to ensure the data is reliable and accurate. This is where data cleansing comes in. It's like giving the puzzle pieces a thorough cleaning, getting rid of any noise, inconsistencies, or errors that might hinder our understanding.
Once the data is clean, we move on to data processing. This step involves transforming the raw data into a format suitable for analysis. It's like shaping the puzzle pieces to fit together smoothly, preparing them for the next exciting phase. Data staging is where we prepare the data for further exploration. Think of it as setting the stage for our analysis, ensuring all the necessary elements are in place. Then, through data clustering, we start to uncover patterns and relationships within the dataset. It's like identifying groups of puzzle pieces that belong together, revealing the underlying structure.
Once the patterns are identified, it's time for data modelling. This step employs statistical and machine learning techniques to build models that can predict future outcomes and behaviours. It's like using the puzzle pieces we've assembled so far to anticipate what the final picture might look like.
After the valuable insights are extracted, data scientists will engage in exploratory work, text mining, regression analysis, predictive analysis, and qualitative analysis. These techniques allow us to dig deeper into the data, extracting even more meaningful insights. It's like examining the intricate details of the puzzle, exploring its colours, shapes, and textures.
Of course, insights alone are not enough. We need to effectively communicate our findings. This is where data visualisation comes into play. We use charts, graphs, and interactive dashboards to visually present the insights. It's like showcasing the completed puzzle in a way that captivates and engages others, helping decision-makers understand and act upon the information.
In a nutshell, data science is a captivating field that follows a complex yet rewarding journey. It combines various processes, methodologies, and analysis techniques to transform raw data into valuable knowledge. By leveraging data-driven insights, organisations can make informed decisions and gain a competitive edge in our data-driven world.
Why is there a need for Data Scientists?
Here are some recent facts related to data sources, shedding light on the sheer volume of data generated globally and the challenges associated with processing it.
- After analysing all the data that is currently available worldwide, around 70% of it is user-generated, according to a DM News report. (Reference: DM News)
- As per an estimate, 1.145 trillion megabytes of data are generated on a daily basis.
- Statista estimates that in 2021 around 79 zettabytes of data/information was created, consumed, collected, and duplicated globally. (Reference: Statista)
- As per the forecasts made by CrowdFlower in its Data Scientist Report, text data makes up 91% of the data utilised in data science. It further showed unstructured data consisting of 33% images, 11% audio, 15% video, and 20% other types of data in addition to text. (Reference: CrowdFlower Data Scientist Report)
- The global datasphere has 90% replicated data and 10% unique data.
- In the international digital universe, between 80% and 90% of the data is unstructured, as per an article published on CIO. (Reference: CIO)
- A user of the internet today would need 181 million years to download all the data from the internet.
- In 2020, about two Data Science professionals joined LinkedIn per second.
- In 2020, every person on earth has produced nearly 2.5 quintillion bytes of data daily and each person has produced about 1.7 MB of data each second. (Reference: Domo)
These data science facts shed light on the massive volume and variety of data being generated globally, underscoring the need for data scientists and advanced data analytics techniques to harness the potential insights contained within this wealth of information.
