A critical issue in Big Data management is to address the variety of data–data are produced by disparate sources, presented in various formats, and hence inherently involves multiple data models. Multi-Model DataBases (MMDBs) have emerged as a promising approach for dealing with this task as t...
Big data is not only “a lot of data” or “more data that I can handle.” We define big data as data having three characteristics: volume, velocity and variety. The first characteristic is volume. What someone calls “big data” often means that the data is much more than this person...
• Structured: The data that can be stored and processed in a fixed format is called as Structured Data. Data stored in a relational database management system (RDBMS) is one example of ‘structured’ data. It is easy to process structured data as it has a fixedschema. Structured Query ...
Big data analytics refers to the systematic processing and analysis of large amounts of data and complex data sets, known as big data, to extract valuable insights. Big data analytics allows for the uncovering of trends, patterns and correlations in large amounts of raw data to help analysts ...
