ABSTRACT--- Big data refers to significantly a wide range of Structured data: is utilized to allude to the data which is large data sets that are extreme or complex for traditional data- as of now put away in databases, in an arranged way processing. Data offers a great statistical power, where data with (conventional line segment databases) higher complexity (more columns or attributes) may give on to Unstructured data: This data have no reasonable false discovery at higher rate. Statistics is a kind of science which helps to make improved decisions in business and economics and arrangement away. The greater part of the data a man in other disciplines. Data summarization, analysis, and extracting experiences has a place with this class. useful inferences which lead to enhanced decisions. These Semi-structured data: Data that isn't in the customary improved decisions help to progress the current status of the database arrange as structured data, yet contain some country, department, a company or the entire economy. This hierarchical properties which make it less demanding to paper provides a brief insight in types of analytics and process. Eg: NoSQL reports. understand the scope of prescriptive analytics in detail and its advantages of applying it on big data. This paper also summarizes the most trending challenges, characteristics and tools used in business analytics and also give an insight on prescriptive analysis and its importance in business analytics. Keywords — Big data, Analytics, Business Intelligence, Business Analytics, Prescriptive Analytics.

NEED , IMPACT AND SCOPE OF PRESCRIPTIVE ANALYTICS

Importance of analytical Results Analytics are the guideline to make decisions in future. Nearly 67% of big data belongs to one of a kind forms of unstructured information generated by means of numerous enterprise packages as proven in figure-3 and consequently those organizations are missing the possibility to leverage the full fee to acquire information discovery from the ones statistics which might be beneficial to growth their earnings, manufacturing and so on. Schubert [2] says “when you get to a point where there may be an excessive amount of complexity for guide tactics, you need to look at introducing new technology to automate procedures and simplify things”.

Figure 4: Types of Analytics

Predictive Analytics: An investigation of likely situations of what may occur. The expectations are generally a predictive figure. Which utilize measurable models and figures procedures to comprehend the future and reply: "What could occur?" Prescriptive Analytics[5]: This kind of examination uncovers what moves ought to be made. This is the most significant sort of investigation and normally results in standards and proposals for following stages. Which utilize improvement and recreation algorithms to counsel on conceivable results and reply: "What would it be advisable for us to do?"

Reactive maintenance[2] (also known as "breakdown maintenance") are repairs that are done when equipment has already broken down. Reactive maintenance focuses on restoring the instrumentality to its traditional operational condition. Preventive maintenance[3]: It is a business assets maintenance approach that involves periodic or scheduled inspection of business assets, equipment, tools, machines and their parts even when they are operational at workplace or plant. Basically, preventive maintenance may be a routine maintenance to stay business instrumentality up and running to forestall sudden and expensive downtimes.

The world is moving towards a lot of connected future, and large knowledge solutions are progressing to play a giant half in automation and development of AI technologies. Firms like Google are already exploitation Machine Learning processes for bigger preciseness in delivering their services. As technologies round the globe become a lot of synchronous and practical, Big Data can become the core that connects them along. Therefore, firms exploitation Big Data solutions got to maintain with its evolving nature whereas those still reluctant to take a position ought to rethink their structure policies. There are a number of pointers which might be useful in obtaining the foremost solutions out of your investment in Big Data by analysing them well and take appropriate decisions to withstand the heavy competition in future .
