The Story of Big Data
In the early days there was a period when people traveled between villages village using a horse-driven cart. However, as times passed, villages converted into towns and towns were spread out. The distances between one town to the next town was also increasing. It became difficult traveling between town and also the baggage. Then, out of the blue one of the smartest fellas suggested that we groom and feed horses more often, as a way to fix the issue. EASILY think about this suggestion, it's not too bad however, do you believe horses could be transformed into elephant? I'm not sure. Another smart person said, rather than one horses pulling the cart why don't we have four horses pulling this same wagon. What are your thoughts of this idea? I really believe it's a fantastic solution. Nowadays, people can cover vast distances in a shorter period of time and carry more baggage.

The same idea pertains to Big Data. Big Data says, till the present, we were content in storing data onto our servers due to the size of data was small and the time required to process the data was also acceptable. In today's technological age, data is increasing prematurely and people are dependent on data a lot of times. Because of the speed with which data grows, it's becoming difficult to store it on any server.

Through this website , Big Data Tutorial, why don't we examine the source that are the foundation of Big Data, which the conventional systems have didn't process and store.

Big Data Driving Factors
The quantity of data available on the earth is increasing rapidly because of many reasons. Divers sources and our day-to- every day activities produce a massive amount information. Thanks to the advent of the web each of the globe has gone online and everything we do results in a digital footprint. With smart objects being brought online and data growing, the rate has accelerated. The primary source of Big Data are social media websites, sensor networks, digital images and videos, mobile phones transactions, purchase records, web logs health records, archives security for military, commerce complicated scientific research , and more. The totality of these data sources is about Quintillion bits of information. In 2020, the quantity of data will reach 40 Zettabytes, that is add up to adding every grain of sand that exists on the planet multiplied by seventy-five.

Precisely what is Big Data?
Big Data is really a term that identifies an accumulation of data sets which are huge and complex. They are difficult to control and store using the available databases management tools or conventional software for data processing. The issue is in the collection, curation, storage and sharing transfer, analyzing, and displaying the data.

Explore Curriculum Big Data Characteristics
The five traits which are the basis of Big Data are: Volume Velocity, Variety Value and Veracity.

Volume
Volume refers to the "quantity of data' that is increasing daily at a rapid pace. The volume of data created by computers, humans, as well as their interactions on social media marketing is enormous. Researchers have estimated that up to forty Zettabytes (40,000 Exabytes) will be created in 2020, that is an increase of 300 times over 2005.Velocity
Velocity refers to the rate at which different sources create data every day. The info stream is huge and constant. Data Analysis Courses Online of users on Facebook is 1.03 billion daily active users (Facebook DAU) on Mobile currently this can be the increase in 22% from year to year. This shows how rapidly the amount of people using Facebook keeps growing on social media marketing , and how quickly data has been generated every day. When you can deal with the pace and data, you can make insights and make actions based on data that is real-time.
Variety
There are many sources that are making contributions to Big Data and Big Data, the kind of data they produce differs. It may be structured, semi-structured , or unstructured. Thus, there's an array of data that's generated each day. During the past, we would have the data using Excel and databases, but now the data is coming as audios, images video, sensor data, and more. as illustrated in the below image. That is why this type of data that is not structured poses challenges in terms of capturing, storage in addition to mining and analyzing information.
ADVANCED
After having discussed volumes, Velocity, Variety and Veracity and Veracity, there's yet another V to consider when analyzing Big Data i.e. Value. It's all very well in fact it is great to have access massive levels of data, but unless we're able to change it into value , it isn't worth it. With regard to making it value I'm discussing, is it adding to the success of the firms that are studying huge amounts of data? Will be the companies engaged in Big Data achieving high ROI (Return on Investment)? If it generally does not add to their earnings by using Big Data, it is ineffective.

In Variety the article, there are many kinds of data that are being generated every day. Therefore, let's know the various kinds of datathat are available:

The types Big Data
Big Data could be of three kinds:

Structured
Semi-Structured
Unstructured
structured
The data that's processed and stored in a predetermined format is referred to as structured data. The data stored in a relational database management software (RDBMS) can be an instance of structured data. It is simple for structured data processing since it is really a fixed schema. Structured Query Language (SQL) is generally used to manage these types of Data.
Semi-Structured
Semi-Structured data is a kind of data it doesn't possess a formal structure as an data model i.e. an underlying table definition in the relational DBMS However, it is organized by properties such as for example tags along with other markers to differentiate semantic elements, which make it easier to study. XML documents also known as JSON documents provide examples of semi-structured information.
Non-structured
The data which has no shape and can't be saved in RDBMS and can not be analyzed without being converted to a format that is structured. It is referred to as unstructured information. Text Files and multimedia files like audios, images videos, and images are examples which are unstructured. Unstructured data keeps growing faster than other types, and experts claim about 80 percent information in an organization is not structured.
So far, I've only covered the basics to Big Data. Additionally the Big Data tutorial talks about a few examples, applications and issues within Big Data.
