Discuss about the Big Data Anaytics.
Big data analytics gather large amount of data and successful insights and specific patterns on them. This uncovering of information can help the companies or organizations involved make decisions that are more informed. This big data analytic concept has evolved in recent times and organizations or companies feel the need to collect large sets of information to analyze them and apply them in their business.
This report discusses about the meaning of big data analytics, and its working. It also covers the way it is used and the benefits and disadvantages of the system.
This big data analytic concept has evolved very much from the ancient times and organizations or companies feel the need to collect large sets of information to analyze them and apply them in their business (McAfee and Brynjolfsson 2012, p5). In the year 1950, companies and organizations used to collect all the information and store them in a spreadsheet to analyze them, which took too much time to implement and lacked the ability of fast implementation. With the introduction of big data, efficiency and speed is improved to a much extent.
Big data refers to the acquisition of large data that are very large to be accessed by normal data processing applications. The challenges on big data are storage, analysis, search, transfer and sharing. Big data analytics refer to the term of capturing predictive data or user behavior analytical data that extracts information from a particular skill set of varying sizes.
The data sets grow rapidly due to the sensing of information from various devices. Since 1980, the technological per-capita has increased 40 times in the modern era. Every day, (2.5*10^18) 2.5 Exabyte of data is being generated. “From 2005 to 2020, the global data volume will increase by a factor of 300” (Hu et al. 2014, p1). To handle such large amounts of information, relational database management system (RDBMS) or desktop statistical packages lags behind to gather such amounts of data, as they need to be handled in hundreds or thousands of servers.
According to Gartner and the most of the industries, the big data is defined by the 3Vs model (Fahad et al. 2014, p269). Big data is said to be high volume, high variety information and high velocity of assets gathering that made an innovative process of information gathering to enable automation of process and making of decisions.
Big data analytics is used to store and process large amounts of data that cannot be successfully analyzed by small data applications. However, there are large amount of technologies that big data analytics provide help in certain sectors.
The various uses of big data are used in mostly every industry as well as in government decisions.
Many benefits are provided by big data analysis over data science. Data science is a way of applying statistical and mathematical knowledge to get certain insights to find patterns and information.
Big data analysis is used in almost every industry. However, it poses some disadvantages that are required o be addressed.
Conclusion:
Big data analytics often gather information from internal as well as external sources. The requirements of third party sources are also required to do the job. However, this effective searching process is risk-based and is very open which provides the possibilities of data breach in the system. Thus, it is concluded in the report that the advantages provided by the use of big data analytics can successfully change the process of doing things, but certain steps are to be taken so that the work done does not provide risks to the system.
