Big Data Helps With Right Decision
Big data is a very popular term used to describe the growth and availability of the data, in both structured and unstructured form. Big data is as important to business, society, as the Internet has become common. Huge data requires more accurate analysis. More precise analysis may lead to more confident in decision making. And the better decisions can make greater operational efficiency, cost reductions and it also reduced risk. It is usually defined as data that includes data sets with sizes beyond the capability of commonly used software tools to capture, to be curate, and to manage, to process the data within a tolerable elapsed time. Big data “size” is a constantly an moving target.
Characteristics of Big data
Volume – The name ‘Big Data’ itself is a term which is linked to size and therefore its characteristic. It is the size of the data which decides the value and ability of the data under thought that whether it can actually considered Big Data or not.
Variety – The next characteristic of Big Data is its variety. This helps the people, who are analyzing the data very closely and who are very much associated with it, to successfully use the data upto their advantage and maintain the importance of the Big Data.
Velocity – The term ‘velocity’ refers to the speed up the generation of data or it can be said that to know how fast the data is generated and being processed to meet the demands and the challenges which are waiting ahead in the path of growth and development.
Variability – This is the factor which can be a trouble for those who are analysing the data. As this refers to the contradiction which can be shown by the data at times, it leads to obstructing the process of to handle and manage the data effectively.
Veracity – The quality of the big data which is being captured can differ very much. The exactness of analysing of the data depends on the veracity of the main source data.
Complexity – Managing the data become a very difficult process, especially when there are large volumes of data, coming from the various sources. Such data is to be linked, connected and then correlated to capture the information that is supposed to be transmitted by these data. Therefore this situation, is called the ‘complexity’ of Big Data.
Technology Used: Big data requires outstanding technologies to powerfully process the large quantities of data within satisfactory elapsed times. Big data has boosted up the demand of information management specialists, which includes some of the companies such as:
• Software AG
• Oracle Corporation
• Dell etc…
Facts and Figures – Big Data
Some other online portal use big data, some facts and figure are here below
