Let’s believe you and I have just started a business together. Now, what’s the core purpose of our business! To serve our customers, right? Well, how will we serve your customer then! Obviously by knowing some specific facts about them. But the crucial part is these facts don’t remain the same all the time. Most of these are variables and their values change over time and it’s quite common. So, what we need to do is, we will have to collect all kinds of data related to those facts from time to time. It may seem easy when we are dealing with a few queries. We can take help online or go to the field and collect all data we need, sounds ok for now. But how about we have a huge list of queries and we need to collect them at every moment! Looking online or going to the field won’t work anymore. Things will get much tougher then. Sometimes, it will happen like the data we have collected doesn’t fulfill all the things that are required right now to make smart decisions for our business. We need more data to keep your business up and running smoothly. Well, not only we, the whole world is already facing this crisis. That’s where the charm ‘Big Data Analytics’ has come into play with a marvelous solution.

The Definition Of Big Data Analytics

Big Data Analytics (BDA) is a complex process that works on very large, diverse data sets that include structured, semi-structured, and unstructured data collected from various sources and the size of data may range from terabytes to zettabytes (one zettabyte is equal to a trillion gigabytes).

Big Data Analytics is used to uncover hidden patterns, unknown correlations, market trends, customer preferences, and other useful information. The data sets for Big Data Analytics aren’t like those normal databases that are used in various business organizations. The type and size of these data sets are beyond the ability of our traditional relational databases. The ability to capture, manage and process the data of these data sets with low latency is also much higher. Big Data Analytics can give us all kinds of data we need for our business using a bunch of great tools and technologies following a set of instructions. IoT, sensors, credit cards, facial recognition cameras, social media activity, heatmaps, cookies, GPS tracking, signal trackers, in-store wifi activity, gameplay, satellite Imagery, employer databases, inbox- all of these are playing as major sources of information for Big Data Collection.

How Big Data Analytics Came Into Existence

People are using the term ‘Big Data’ since the early 1990s. Though it’s not clear how it first came into our life or who first used this term, but the most known fact is about a man named John R. Mashey, who at the time worked at Silicon Graphics, for his effort of making this term popular.

Don’t think that the whole concept of Big Data is new. People have been trying to use proper data analysis and analytics for better decision-making over the course of centuries. Around 300 BC, the ancient Egyptians tried to collect all existing data and store them in the Alexandria library for future use. Also, the Roman Empire used to analyze the military statistics in terms of determining the optimal distribution for their armies. History will surely give us more examples like these.

Time to take a close look, the data generation speed and volume have changed in the last two decades and it has crossed the human limitation of understanding all of them properly. In 2013, the world’s total amount of data was 4.4 zettabytes. But here in 2020, that amount has now become 44 zettabytes. In a word, this is a clear exponential growth. Our modern technologies don’t have enough capabilities to deal with this giant amount of data and give us our required solution. Hence, for the proper use of these huge amounts of data our traditional data analysis opened the gateway of Big Data Analytics.

Types Of Big Data

The whole gigantic world of Big Data is the combination of three types of data- structured, semi-structured, and unstructured data. Let’s take a brief look into these.

1) Structured Data: These data consist of fixed-format, highly organized, and well-defined structures. Most of the time, these data are handled by machines rather than humans. This kind of data is already managed by business organizations in databases and spreadsheets stored in SQL databases, data lakes, and data warehouses.

2) Unstructured Data: This kind of data does not follow any specified format. Unstructured data (Raw data) is hard to categorize in existing databases and it comes in many different formats. Emails, text messages, documents, images, videos, metadata are common examples of unstructured data. To retrieve valuable information from these data Hadoop like clusters or NoSQL systems are used.

3) Semi-structured data: The data that contains semantic tags and elements, do not follow the structure attached to the relational databases are known as semi-structured data. XML, JSON files are common examples of semi-structured data.

How Big Data Analytics Works

The whole process of Big Data Analytics is done by four consecutive steps- collecting, processing, cleaning, and analyzing. Large datasheets need to go under these 4 steps to extract the quality data that can help a business for their further operations. Let’s see how these 4 steps are done.

1) Data Collection: In today’s world, the process of data collection is different for each business organization. With the help of today’s technology, business organizations collect both structured and unstructured data from cloud storage to mobile applications to in-store IoT sensors and beyond. These data are collected from a vast amount of resources. Some data are stored in the data warehouses, which makes the business intelligence tools and solutions (BI Platforms) access these data efficiently. Unstructured data are stored in a data lake because of its complexity.

2) Data Processing: To get the required information from the collected data, data processing is mandatory. Data is being generated at an exponential rate, so properly organize these data has now become a real challenge. We have two options in our hands for data processing. The first one is batch processing, which is an effective way of processing a huge amount of data that has been collected over a period. And another option is Stream processing that lets the users get their required results based upon their query within the shortest possible time. Point to noted that stream processing is much costly than batch processing.

3) Data Cleaning: To ensure data quality and get stronger results, data cleaning is a must. In this process, all data get proper formation and the useless data gets eliminated. Then the final data gets accounted for better decision making.

4) Data Analyzing: Here comes the last and final step. Now all things that require data analysis is done and it’s time to convert the valuable data into valuable insights. There are lots of methods for Big Data analytics, I am mentioning some of them below-

  • Data Mining: This process analyzes a massive volume of data to discover hidden patterns of data according to different perspectives to categorize useful information.
  • Predictive analytics: This is a branch of advanced analytics that uses data with the help of statistical algorithms and machine learning techniques to make future predictions of various unknown events based on present data.
  • Machine Learning: In this system, Big Data is used by its algorithms to define the incoming data and to identify patterns attached to it. This system transforms data into valuable insights that we can use for further business operations and automate some processes of decision-making.
  • Deep Learning: This is part of machine learning that imitates the way humans gain certain types of knowledge and patterns by relying on the layers of Artificial Neural Network (ANN).

The 6Vs Behind Big Data

We can describe Big Data properly with 6Vs. When Big Data first came into existence, there were only 3Vs. Don’t think that it’s over in 6Vs, the number of Vs is always increasing depending on the need for Big Data. Let’s dive into these 6Vs.

1) Volume: In ‘Big Data terms, volume refers to that we are dealing with a gigantic amount of data. These data can be of unknown value, like how often a website has been visited, how many clicks have happened on a webpage, or mobile phone. Gigabyte can’t help us now to measure the size of these data, we need Zettabytes (ZB) or even Yottabytes (YB) to help ourselves in this field.

2) Velocity: Velocity shows us how fast data is being received or transmitted. When data is streamed directly into memory rather than written on a disk, the speed will be much higher, and it can provide real-time data in this environment. Velocity is the most vital V among others cause it’s linked to machine learning and artificial intelligence.

3) Variety: Variety means the types of data that are available in the large datasheets. These data can be structured or unstructured. Processing this data is a crucial part of Big Data Analytics when the data itself is changing rapidly.

4) Veracity: Veracity describes the data accuracy level of the data sets. Data are coming from lots of resources. We need to verify our data every time to avoid any chaos. Unverified low-quality data will direct organizations to make irrelevant decisions.

5) Variability: A single piece of data can be used for multiple purposes. So, to use data for multiple purposes, we need to format data in many ways. This will save a huge time as the total process to come this far again is too lengthy. Variability refers to the same thing as using data for multiple purposes to get efficient results in a short time.

6) Value: Value is the last V of these 6Vs. Valuable data will be extracted out from the large data sheets that will benefit organizations in better decision making. Irrelevant data are needed to be cleaned out to avoid any kind of false alarm for any current purpose.

Big Data Tools And Technologies

No matter what, we need Big Data but we can’t stop its growth rate in any way. To deal with this massive amount of data, we need more advanced technologies. The good news is the tools and technologies that we use for Big Data Analytics are developing faster to tackle the situation. Different organizations use different kinds of tools and technologies for Big Data Analytics. And the most interesting part is there are lots of tools and a huge part of them is open source. Let’s dive into the top 10 open sources Big Data Tools that are used in this field.

1) MongoDB: MongoDB is a cross-platform document-oriented database program, comes with the scalability and flexibility that is needed for querying and indexing.

Smart grids offer a two-way flow of data and power between consumers and suppliers. The data from smart meters are used to analyze power planning, energy optimization, and customer satisfaction.

Big Data Comes With Big Challenges

Great opportunity comes with great challenges, the same goes for Big Data too. Without proper extraction from raw data, Big Data can be a big danger for the whole world. Let’s take a look at some remarkable challenges faced in this domain.

1) Data Synchronization difficulty between multiple sources: Extracting valuable data from a giant data sea is quite a sneaky task indeed. Data synchronization is an essential part of this process to maintain data consistency. Data synchronization raises some big problems when the data origination points increase, mainly for isolated and diverse data. Though some vendors are serving quality tools, still many organizations haven’t sorted out this problem.

2) Massive amount of Data Management: Big Data can open doors for big achievements no doubt. But after the data storing part, the data management part still gives us some noteworthy troubles. As the amount of Big Data is increasing, the lack of management is getting clearer day by day. One of the solutions to sort out this problem can be the implementation of combined hybrid relational databases and NoSQL databases.

3) Data privacy and security concerns: We can easily address this as a top issue without any arguments. Big Data contains an enormous amount of sensitive information, so the security needs to be very high for maximum protection. But the security model that we see now in today’s world for Big Data is not effective enough. The open-source tools that are used for this analytics are not designed to keep security concerns in mind and this drives to many unknown threats.

4) Huge cost for Big Data management: Big Data has some obvious costs, such as cost for data storage infrastructure, software maintenance, hiring professionals, data backup cost, and networking data cost. Apart from these, there are miscellaneous costs that arise from various sectors. When organizations need more data for their business all of these costs rise proportionally. Organizations can use data lake as their data storage as it is the cheapest way, but the other costs need attention to proper planning and strategies.

5) Search for the right Big Data Talent: Finding the actual person as per an organization’s needs is too hard. Without skilled and experienced professionals, the whole setup will be a complete failure. To resolve this problem, organizations are using machine learning, artificial intelligence(AI), and automation to extract meaningful data.

Future Of Big Data

As time passes, the number of business organizations that are adopting this data-driven technology is increasing. Because of the exponential growth, storing data on physical devices won’t be possible anymore. A report from Seagate shows that the global data quantity will reach 175 zettabytes by 2025. To handle the situation data will be stored in a hybrid and multi-cloud environment. To extract out valuable data, the demand for data scientists and Chief Data Officer(CDO) will increase. To keep the whole system safe against any vulnerability more security and privacy concerns will arise. Humans will buy more algorithms than software. AI and machine learning will dominate this sector and altogether this will be used as a merge technology. Data will be more refined and will give us more fruit than the present. Maybe, we won’t use the term Big Data anymore, rather we will call it Smart Data.
