BIG DATA
Whаt is big dаtа?
- Big dаtа is а соmbinаtiоn оf struсtured, semistruсtured аnd unstruсtured dаtа соlleсted by оrgаnizаtiоns thаt саn be mined fоr infоrmаtiоn аnd used in mасhine leаrning рrоjeсts, рrediсtive mоdeling аnd оther аdvаnсed аnаlytiсs аррliсаtiоns.
- Systems thаt рrосess аnd stоre big dаtа hаve beсоme а соmmоn соmроnent оf dаtа mаnаgement аrсhiteсtures in оrgаnizаtiоns, соmbined with tооls thаt suрроrt big dаtа аnаlytiсs Big dаtа is оften сhаrасterized by the three V's:
- the lаrge vоlume оf dаtа in mаny envirоnments;
- the wide vаriety оf dаtа tyрes frequently stоred in big dаtа systems; аnd
- the velосity аt whiсh muсh оf the dаtа is generаted, соlleсted аnd рrосessed.
- Аlthоugh big dаtа dоesn't equаte tо аny sрeсifiс vоlume оf dаtа, big dаtа deрlоyments оften invоlve terаbytes, рetаbytes аnd even exаbytes оf dаtа сreаted аnd соlleсted оver

Significance of Big Data in India
- With a population of around 1.3 billion, Big Data holds a significant position in the Indian context.
- As per the study conducted by NASSCOM, “the Indian analytics industry is predicted to reach $16 billion mark by 2025.
Government Initiatives & Interventions
- NITI Aayog is currently working on a plan in collaboration with the private players to develop the‘National Data & Analytics Platform’, which will act as a single source of sectoral data for citizens, policymakers, and researchers.
- ‘Big Data Management Policy’ drafted by CAG for auditing large chunks of data generated by the public sector in the states and the union territories, is a great start.
- Ministry of Statistics and Programme
Implementation has proposed to establish a ‘National Data Warehouse on Official Statistics’ which will leverage technology and use big data analytical tools to improve the quality of macro-economic aggregates. - Use of Direct Benefit Transfer in MGNREGA & Aadhaar for authentication& availing welfare scheme benefits helps in the filtering of ghost beneficiaries.
- The Ministry of Agriculture has signed a deal with the ISRO to use satellites for mapping of agricultural assets.
- Smart City Mission, Digital India, digital economy proposals like BHIM app, inter alia are important government initiatives that are using Big Data for achieving good governance in the country.
Challenges
- Invasion of Privacy: Big Data Analytics leads to the twin problems of digitization, which are, Data privacy and Net neutrality.
- Data Security: Several incidents of leakage of Aadhaar data underlined the need for the government to increase the security and safety of virtual data it collects from its citizens.
- Technical Challenges: As the name suggests, Big data involves several inherent limitations like,
(i) Inefficient infrastructure for data collection & management of such humongous data,
(ii) Storage & computational problems,
(iii) Scalability & streaming issues. - Challenges related to Governance: For effective policymaking using Big Data, the government needs to adopt a consistent dynamic approach. Constant evaluation of the generated feedback and flexibly changing the related policy structures will percolate the benefits to the lowest level.
Way Forward
- Ethical issues related to data privacy need to get addressed.
(i) Data protection law must incorporate some of the best practices followed in the World.
(ii) It must strengthen cybersecurity in order to safely utilize the large pool of virtually available data. - Economically, the alliance of big data with blockchain technology will potentially change the way we see big data for now.
- Infrastructural Requirement: To effectively analyze the large chunks of available data, well-equipped data centers are needed. It is essential to segregate the relevant data from the irrelevant data pool.
- In a world where most of the governments & businesses rely more on new-age data sources such as satellite imagery, parking images, and night lights, Big Data governance could be a game-changer for India, where policies have for long been under-implemented.
- Big Data is like a double-edged sword. It will be wise to handle it with utmost care and conscience.
