The major challenge of Big Data is extracting the useful information from the terabytes of raw data and analyzing the extracted information which is essential for the decision making. The above factor can be found in the proposed system which is simplified in three units. The first, Data Acquisition Unit (DAU) filters the collected data. The second, Data Processing Unit(DPU) process the data by collecting the useful information and the third, Analysis and Decision Unit(ADU), analyses the reduced data and supports decision making.
