Introduction to Big Data
Big Data: is an interesting topic that I am going to introduce to you all and it is a topic that everyone seems to be talking about these days. With the advancement of technology in the current generation everyone is keen on knowing what big data really is and to know if this really is a special type of data. It is always a question to know where this data is coming from, how it is processed and what are the results and how are these results being used?
In this post I will introduce you to what big data is and what it really means for the most changing and challenging world we all live in.
What is Big Data?
It definitely is not a ‘special’ type of data. Also, there is no exact definition to define what Big Data is. But let me define it for you in very simple words. Big data as the name describes, it deals with a lot of data. People think they know it all, but they really don’t know. Typically what defines big data is the need big data is the need for new techniques and tools in order to be able to process it.
To use big data you are required to have programs which has the ability to span multiple physical or virtual machines. This is a major requirement because a reasonable span of time is required to process all of the data. By having multiple machines, each program knows which parts of the data that needs to be processed. Followed by this process, the results can be put together from all the machines that were used to process these data to actually make sense of a large set of data.
What kind of datasets are considered as Big Data?
A typical example for big data can be social media networks analyzing data of their members. This data can be used to learn more about them and help the members connect with content that interests them.
Transactional data and sensor data are two of the largest data sources. Stock prices, bank data can be considered as transactional data and sensor data is commonly referred to Internet of Things (IoT).
What tools are used to analyze big data?
Apache Hadoop which is a tool that is used to analyze big data is also one of the most influential tool. If I am to provide a description of Apache Hadoop it is a framework is a that allows for distributed processing of large data sets across clusters of commodity computers using a simple programming model.
There are many tools out there in the market that is available to analyze big data. These tools are specialized in such a way where these are able to provide features and performance for a specific niche or specific hardware configurations.
Big data continuously grows day by day, and it is not going to stop. Therefore, as big data grows, the open source tools that are available to analyze these data will also grow alongside.
