The high-degree photonic integration promises small-form-factor and low-power transceivers for future coherent systems. In this paper, we provide an overview of state-of-the-art research issues and achievements in the field of analytics over big data, and we extend the discussion to analytics over big multidimensional data as well, by highlighting open problems and actual research trends. While in case of big data as the massive amount of data is segregated between various systems, the amount of data decreases. We can group the challenges when dealing with Big Data in three dimen-sions: data, process, and management. Reducing the latency from data processing capacity of conventional database systems. On the other <>stream Opportunities are increasing as the volume of Big Data is also increasing and predicted to grow enormously because of the technological revolution, which includes but not limited to various mobile devices. This broad adoption and ubiquitous usage has stretched the initial design well beyond its intended target, exposing two key shortcomings: 1) tight coupling of a specific programming model with the resource management infrastructure, forcing developers to abuse the MapReduce programming model, and 2) centralized handling of jobs' control flow, which resulted in endless scalability concerns for the scheduler. Until now a lot of tools and frameworks were generated to capture, store, analyze and visualize it. 1.)Introduction! New authentication concept using certificates for big data analytic tools.
