I believed that knowledge increases by sharing and not by saving, so I would like to share my knowledge of big data with you briefly. Big data literally big data, it is a huge collection of data sets.
Big data is not merely data to think upon, but it is a complete subject. Big data includes frameworks, techniques, and various tools. Big data is the one, which cannot be processed by the usual computing techniques. Big data is a union of data from several applications and devices. It can be categorized in three ways structured data, semi-structured data, and unstructured data.
The list of fields from which the data can be extracted
The family members of the big data are as below:
Social Media Data: Social media such as Twitter, LinkedIn, Facebook stores the information and the views posted by people who have their accounts across the globe.
Power Grid Data: Power grid data stores the data utilized by an appropriate computer with respect to a base station.
Black Box Data: it is a component of the helicopter, airplanes, and jets, etc. it holds the information of the performance of the aircraft and catches the voices of the flight crew, recording microphones and earphones.
Stock exchange data: This catches the data about “buy” and “sell” decisions taken on a share of different organizations made by the customers.
Transport Data: The transport data includes model, capacity, distance, and availability of a vehicle.
SEO Data: Search Engine Data will collect the data from various databases.
Big Data technologies
The most suitable technologies which are capable of solving the issues of big data effectively are mentioned below.
Hadoop
Hadoop is an open-source software platform for handling big data. Hadoop created a specific platform for structuring big data and makes it more essential for analysis purposes. It has gifted the best features such as data distribution and faster processing, thus, Hadoop is critical for any business handling big data.
The Hadoop is more suitable for large files rather than large quantities of small files. It is a known fact that Hadoop is an open-source platform and uses commodity hardware, which makes it more affordable and helps in achieving the data. An added advantage of using Hadoop is, it facilitates all kinds of data, such as structured, unstructured, and semi-structured.
MapReduce
MapReduce uses multiple machines to process huge data sets. The MapReduce is basically a programming paradigm that handles big data effectively. The Apache Hadoop framework is a well-known MapReduce framework.
That makes you understand the complete process of handling big data. The Hadoop MapReduce got invented by the implementation of an algorithm, developed and maintained by the Apache Hadoop project.
SkyTree
SkyTree is a machine learning and data analytics policy mainly concentrating on handling big data. It is a high-performance machine learning, in turn, a part of Big Data, since the gigantic data make manual analysis, or even conventional automated exploration methods impracticable or too expensive.

Really great blog, it’s very helpful and has great knowledgeable information. Thanks for sharing, keep updating such a good informative blog.
I work in a large corporation, and in big companies data roles are often, sort of thrown together. So depending on the company you are talking about the role of “data scientist†can mean different things. Sometimes, this can be a very wide spectrum. For example, in one company a data scientist may be a combination of data engineer, business intelligence designer and statistical analyst. While at others a data scientist may only focus on a single type of problem, or technique (like tuning a recommendation engine using machine learning). If you would like to know more about the many different types of data roles that exist check out this post.
I have led decision science teams for big companies and I get this question a lot. I answer it this way. Data science is the combination of domain expertise (like an industry focus), programming, and mathematics. While data science is an awesome field and can be very fulfilling, it can be as frustrating and disappointing as any other career choice, if it isn’t right for you. Many people seem to think about this as a way to get a good job quickly because demand is so high right now. This is not necessarily the case. I encourage people to ask themselves why they want to become a data scientist or any other career choice they may not know much about. Once you answer that for yourself, you can find an awesome career whether it is in data science, engineering, analytics, or something else all together. Here is a link to a “day in the life†post for data scientists who work in corporate settings, that may be helpful.
