Data Science & the need for it
Data Science involves the retrieval of a large collection of raw data belonging to an enterprise, and processing it to get meaningful information that can be used to acquire knowledge consisting of business value for the enterprise.
The importance of Data Science stems from the challenges brought about by big data. Traditional systems have structured data which makes it easier for enterprises to analyze the data using Business Intelligence (BI) tools. But as the volume of data gathered by an enterprise increases in size, the data tends to become unstructured, thereby making Business Intelligence tools inefficient for processing the data. Data Science tools like R, Weka & RapidMiner have been introduced to process huge amounts of data.
Examples of Implementation of data science concepts-
- Data Science algorithms are used by search engines like Mozilla Firefox and Google to process our queries & display search results.
- WhatsApp Web, which allows you to access the app through your computer requires the phone camera to scan a QR code on your WhatsApp web page. This scanning process involves image recognition, which is done using data science algorithms.
- Speech recognition technologies like Alexa, Cortana & Siri also use data science concepts.
- Email services such as Gmail & Yahoo use data science techniques for spam filtering.
- In the field of medicine, disease prediction in human bodies is done using data science concepts. Rate of heart beat & blood glucose levels that are calculated through wearables on the human body like ‘Fitbit’ also employ data science concepts.
