Big Data Analysis Using Distributed Approach on Weather Forecasting Data
Keywords:
Big data, ETL, Data processing unit, RSDU, DADU, real-timeAbstract
Data than it seems at first, and extracting the useful information in an efficient manner leads a system toward a major computational challenges, such as to analyze, aggregate, and store, where data are remotely collected. Keeping in view the above mentioned factors, there is a need for designing a system architecture that welcomes both real-time, as well as offline data processing. Big data is data whose characteristics force us to look beyond the traditional methods that are prevalent at the time. Online news, micro-blogs, search queries are just a few examples of these continuous streams of user activities. Evolving data streams methods are becoming a low-cost, green methodology for real time online prediction and analysis. Heterogeneity, scale, timeliness, complexity, and privacy problems with Big Data impede progress at all phases of the pipeline that can create value from data. The problems start right away during data acquisition, when the data tsunami requires us to make decisions, currently in an ad hoc manner, about what data to keep and what to discard, and how to store what we keep reliably with the right metadata.
