The World Of Big data

    • What is Big Data?

      Big Data is not just data but it is a collection of large datasets, frameworks, techniques, and tools. The datasets of Big Data cannot be processed using traditional data processing techniques thus the new framework, tools and techniques are used.

      Benefits

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

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

      Challenges with using Big Data

      Difficult to capture huge volumes of data

      Considering the volume and variations in data, it is not easy to capture Big Data with the help of traditional less-powerful data management systems.

      Organization of data

      Since Big Data is comprised of different types of data that differ in terms of formats and sizes, it is challenging to organize the data in one single platform.

      Storage Space

      In order to store Big Data, the platform must contain huge storage space and data processing system.

      Data Retrieval

      From those huge volumes of data, it is challenging to locate a particular data required at a short period of time.

      Data Sharing & Transfer

      Sharing of big data from one system to another requires a high speed transferring medium with huge storage capacity.
