Overview

The concept of big data has been around for years; most organizations now understand that if they capture all the data that streams into their businesses, they can apply analytics and get significant value from it. But even in the 1950s, decades before anyone uttered the term big data, businesses were using basic analytics (essentially numbers in a spreadsheet that were manually examined) to uncover insights and trends. The new benefits that big data analytics brings to the table, however, are speed and efficiency. Whereas a few years ago a business would have gathered information, run analytics and unearthed information that could be used for future decisions, today that business can identify insights for immediate decisions. The ability to work faster - and stay agile - gives organizations a competitive edge they didn't have before. Large data sets can be in the form of large files that do not fit into available memory or files that take a long time to process. A large data set also can be a collection of numerous small files. There is no single approach to working with large data sets, so MATLAB includes a number of tools for accessing and processing large data. Begin by creating a datastore that can access small portions of the data at a time. You can use the datastore to manage incremental import of the data. To analyze the data using common MATLAB functions, such as mean and histogram, create a tall array on top of the datastore. Big data analytics examines large amounts of data to uncover hidden patterns, correlations and other insights. With today's technology, it's possible to analyze your data and get answers from it almost immediately - an effort that's slower and less efficient with more traditional business intelligence solutions. MATLAB has the tools to work with large datasets and apply the necessary data analysis techniques. This book develops the work with MATLAB for the processing, exploration and visualization of data.
