Introduction Of Big Data Analytics

Big data analytics refers to the process of collecting, organizing and analyzing large sets of data to discover patterns and other useful information. An enormous amount of data often referred to as Big Data is getting generated everyday by diverse segments of industries like business, finance, manufacturing, healthcare, education, research and development etc. Big data analytics will help organizations to better understand the information contained within the data and will also help identify the data that is most important to the business and future business decisions. Big data analysts basically want the knowledge that comes from analyzing the data. The healthcare industry historically has generated large amounts of data, driven by record keeping, compliance & regulatory requirements, and patient care. While most data is stored in hard copy form, the current trend is toward rapid digitization of these large amounts of data. Big Data includes huge volume, high velocity, and extensible variety of data. The data in it will be of three types. Structured data: Relational data. Semi Structured data: XML data and Unstructured data: Word, PDF, Text, Media Logs.

Big data is critical to our life and its emerging as one of the most important technologies in modern world. Follow are just few benefits which are very much known to all of us:

  • Using the information kept in the social network like Facebook, the marketing agencies are learning about the response for their campaigns, promotions, and other advertising mediums.

  • Using the information in the social media like preferences and product perception of their consumers, product companies and retail organizations are planning their production.

  • Using the data regarding the previous medical history of patients, hospitals are providing better and quick service.

Big data technologies are important in providing more accurate analysis, which may lead to more concrete decision-making resulting in greater operational efficiencies, cost reductions, and reduced risks for the business. To harness the power of big data, you would require an infrastructure that can manage and process huge volumes of structured and unstructured data in real-time and can protect data privacy and security.

There are various technologies in the market from different vendors including Amazon, IBM, Microsoft, etc., to handle big data. While looking into the technologies that handle big data, we examine the following two classes of technology:

  • 1.

    Operational Big Data

    • This includes systems like MongoDB that provide operational capabilities for real-time, interactive workloads where data is primarily captured and stored. NoSQL Big Data systems are designed to take advantage of new cloud computing architectures that have emerged over the past decade to allow massive computations to be run inexpensively and efficiently. This makes operational big data workloads much easier to manage, cheaper, and faster to implement. Some NoSQL systems can provide insights into patterns and trends based on real-time data with minimal coding and without the need for data scientists and additional infrastructure.

  • 2.

    Analytical Big Data

    • This includes systems like Massively Parallel Processing (MPP) database systems and Map Reduce that provide analytical capabilities for retrospective and complex analysis that may touch most or all the data. Map Reduce provides a new method of analyzing data that is complementary to the capabilities provided by SQL, and a system based on MapReduce that can be scaled up from single servers to thousands of high and low end machines.
