What is Big Data Analytics
The relevance of describing any Big Data Analytics Course can be ascertained once we understand the definition of “Big Data Analytics”. Big Data Analytics is a multitude of complex processes involved in analyzing Big Data to detect information about hidden patterns, and correlations between different variables, market trends, customer behavior, and customer preferences. The data to be analyzed is so large that advanced computing techniques and tools are required to cope with the speed of the input originating from different sources like structured, unstructured, and semi-structured data. The source of such data may be varied like website traffic, comments on social media, surveys, data from Internet of Things(IoT) devices, sales volumes, and services. The results are used as tools for making informed decisions.
Characteristics of Big Data Analytics
This section is the opening topic for any Big Data Analytics Course. Any vast amount of data cannot be scrutinized with Big Data Analytics, as it has unique characteristics to identify it. These characteristics are as follows:
