What is Big Data´s use?
-
We all generate an enormous amount of information every day and precisely because of this, new analytical profiles and disciplines have appeared as Data Science which are capable of processing these massive data and convert them into patterns.
Let's say that the objective of Big Data is not entering the micro data when you individually have performed a particular action, what is being sought is, on the basis of the analysis, know when individuals, who admit a common segmentation, performed a certain action.
Thanks to this we can perform tests and strategies predictively with greater guarantees of success than if we did it by pure intuition or heuristics. We live the time of Data Driven strategies.

Examples of application

Now it begins to be transversal to all activity and sector. Thanks to the very high capabilities of current computers process and reducing the costs of hardware and software, which was previously reserved to large corporations has become democratized arriving at all levels.
Financial services may be the first to use it extensively since, for them, it is very useful to determine risk factors for example when granting a loan. On the other side, medical sector which, based on medical records of a population, may be able to predict other kinds of risk factors and cases: clinics when developing certain diseases or treatments for them.
Of course Big Data has also reached marketing. One of the most important keys when launching a new product or simply test a service is the analysis. Using Big Data the hypothesis that we formulate will be much more accurate and therefore, we can better optimize our resources.
