A single Jet engine generates around 10TB of data in 30 minutes of its flight time. With thousands of flights plying about, the data generated can reach to several Petabytes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Data that can be accessed, processed and stored in a fixed format is known as structured data. The computer techniques have developed to a great extent and the format to work with a particular type of data is known in advance now. However, this does not help in cases where the data keeps growing to an extent that it touches multiple range of Zettabyte. That is where the term \u2018big data\u2019 originates. It can be challenging to process and store such large amount of data.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Data that is huge and has no proper structure to it is defined as unstructured data. This sort of data poses several challenges in terms of processing and obtaining a value of it. For instance, a heterogeneous data comprising of images, videos, text files etc can be considered as unstructured data. Several organizations have a huge amount of data but unfortunately are not aware of how to derive value out of it as most of the data is in unstructured format.
A best example to explain unstructured data is output by Google search.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

From the name itself one can have a fair idea about the size of the data being huge. The size of any data is crucial as it helps determine a value out of that data. Also, must understand that just any data cannot be referred to as Big Data. The volume of the data is important in determining whether it can be referred to as Big Data or not. Hence, it can be safely said that the \u2018volume\u2019 of the data is an important characteristic that helps in determining if a data can be referred to as Big Data.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

By variety, we mean both structured and unstructured data. Here, the data can be from several different sources. Earlier, most of the applications used data in the form of either spreadsheets or databases. Today, however, the scenario has changed and data can be of any form; videos, PDFs, audios, photos, monitoring devices and much more. Variety of data brings with uncertainty in terms of mining, analyzing and storing of data.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Along with Hadoop Distributed File Sytems, Apache Spark also works well with other data stores such as Apache Cassandra, Open Stack Swift , etc. Apache Spark also makes testing and development easy as it can be run on a single local machine.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
