What is Big Data? By definition, big data is an approach to analytics, specifically, to deal with large, organized data sets which can represent real-time or historical data and that may involve thousands of nodes. The idea is that the size of the data doesn’t matter, because it will be used to solve problems. In other words, big data allows for analytical problems to be solved at the speed of natural selection, rather than on a traditional time-consuming, piecemeal basis.
Examples include medical imaging, social networks, financial markets, supply chain management, manufacturing systems, and unstructured or semi-structured databases. Apache Hadoop’s mission is to provide a framework which can be used to run applications across a wide variety of systems, using any network architecture. It is an open source project based upon JAVA and is maintained by the Stanford University Library of Software. Because Hadoop supports both the Java Server Pages applications, running on the Internet, it can easily be used as a platform for large data analysis workloads without concern for system compatibility.
What is big data analysis? Basically, it involves using different forms of analytic tools in order to unearth business insights. One tool is used to discover insights by applying a statistical technique called principal component analysis (PCA). Another tool is used to detect trends from the past – it is called backtracking. A third tool is used to extract matrices from large amounts of unstructured or semi-structured data, called machine learning tools.
One of the key ingredients for Hadoop’s success lies in its mapreduce capability. Mapreduce is a framework that is designed to parallelize the job of large Distributed Application Management teams (DAMs) by allowing each team to operate with only a single data warehouse. By only using one copy of the HDA, all the team members can run their programs on the cluster without sharing files, work on their own projects independently, and so forth. The ability to run just one application per team in the MapReduce cluster allows for easy centralization of data analysis tasks, leading to significant cost savings over the traditional Map-Reduce approach.
Big Data has been collecting large amounts of unstructured or semi-structured data for a long time. Since the dawn of the internet, there has been an ongoing effort to collect, classify, and manage this data. The first attempts to do this involved establishing a virtual relational databases on individual computers within a company. Virtual relational databases are useful for managing huge amounts of complex data, but they are limited because they are only accessible by a few specific personnel within a company. This means that for every person who needs access to a social media site on the payroll of one employee, ten other employees would need access to the same information on another employee’s computer.
A second method for managing big data analytically is through the use of two different types of statistical distributions: positive and negative covariances. Distributions such as the log-normal and the binomial are widely used for analyzing the relationships between variables. Positive Covariance and Negative Covariance are more recently studied, but positive correlation and negative correlation have proven to be extremely efficient when it comes to analyzing large amounts of descriptive and statistical data. The main difference between these two statistical distributions is that positive Covariance is linearly associated with a variable, while negative correlation is more exponential.
In addition to leveraging modern technology to analyze big data analytics, a business can also utilize traditional analytics techniques, such as data mining. Many large corporations are turning to data mining to discover unique business opportunities. With this technique, the organization can exploit the analytic clues that the company has uncovered in order to generate in-demand product lines or determine what types of customers are in greatest demand. The insights provided by analytics can greatly influence the success or failure of any given venture.
There are many tools that can be utilized in managing big data analytics. The best option is to explore the services offered by a data analytics provider. These experts will carefully examine each of the raw analytics data sets collected and will then create custom reports, which you can then analyze to understand your unique business challenges. If you are looking for a comprehensive solution to your business analytics needs, an experienced provider can offer you an affordable and fast process of evaluating data sets and extracting valuable insights from them. A provider can help you optimize your current analytics data sets to improve productivity and reduce costs while simultaneously generating new business opportunities.
