The term used for unstructured data is Big Data.
According to NASSCOM analysis and report; the structured data and semi-structured data accounts for only 10% each, whereas, the remaining 80% of data comes from unstructured data. In general, organizations analyze structured and semi-structured data using traditional data analytics tools. Previously, Google developed Map-Reduce framework tool for analyzing unstructured data. Later, Apache developed a framework called ‘Hadoop’, which is equipped with excellent features providing better data analysis and reveals information according to the requirements. Many companies have started to explore new opportunities in the field of unstructured data. However, the privacy and data protection concerns have also risen in the industry.
