Big Data Course Overview

    What is Big Data?

    Big data combines structured, unstructured, and semistructured data that is processed, analyzed and interpreted by corporates to extract actionable insights. Using these insights, businesses can improve their operations, product offerings, marketing strategies, etc., and make them more customer-oriented.


    Big data is also used for several high-tech analytical projects, including machine learning, predictive modelling, etc. This allows the organizations to identify valuable information and use it in diverse ways. 


    Companies follow every behaviourism and preference of the consumers. This, in turn, helps them create an influential marketing platform and better business foundation.

    Big Data Sources

    Companies collect data like texts, phone calls, emails, media, searches, etc. This massive amount of data is beyond the processing capabilities of traditional systems.


    Smartphones, IoT devices, social media apps, search engines, etc., create tons of data daily. For instance, search engines like Google track and store your preferences in your search history and leverage it to offer personalized results. All search engines function similarly, based on the recorded user data. 


    To be more specific, there are three Big data applications, including - 


    Social Data: As the name itself specifies, this data comes from every activity, including liking, uploading, and sharing, constantly occurring on social media platforms. Web searches have also become a great source of big data.


    Machine Data:  Several sensors in public places, such as satellites, road cameras, etc., are also commendable sources of Big Data.


    Transactional Data:  All online transactions on digital platforms are credible Big Data sources.


    Other sources include black box data, stock exchange data, power grid data, transport data, and more.

    Big Data Examples

    Some significant examples of big data are medical records, media & entertainment records, BFSI data, internet logs, search engine history, meteorological data, etc. Other than that, locations are also used to provide the consumers a better view of the geographic information, traffic conditions, weather, and more.


    The use of big data is essential as the companies further use these to provide improved customer service by creating personalized marketing platforms for the users. It is incorporated into the systems of the company and further enhances the revenues and profits of the businesses and gives them an upper hand in the competition. 


    For instance, if you search for a specific genre of music, more suggestions for artists will pop up on your "for you" page. Or, if you search for a type of shoes from a specific website, a similar kind of shoes or website will pop up in your suggestions. This is how Big Data is used to offer a personalized space for every user.


    Certified data analytics help organizations understand the needs of their consumers. It can help companies understand which products are popular among customers and which aren't. This creates an advantage for the company as they can design targeted and customized ads for different buyer personas to boost profits and customer-brand engagement. 


    Not only online, but big data also offers a better understanding of offline space. For example, different branches of shopping markets will not offer the same kind of products. The offerings usually differ depending on the socio-cultural aspects and customer demographic of specific locations.

    Big Data Characteristics

    The characteristics of Big Data include the 5 Vs and more Vs being added. There are numerous algorithms and processes involved in Big Data Analytics.


    Big data is compressed by a wide range of data types, including structured data, financial records or transactions, unstructured data (media logs, documents, etc.), and semistructured data (web searches, streaming data, etc.). This data is cleaned, processed, organized, and analyzed by big data analytics.


    Certified data analytics is so huge in number that it has to be processed through artificial intelligence, where the system observes patterns in data and gives the input as soon as possible.

    What are the 5 Vs of Big Data?

    The three major Vs out of the 5 are - 


    Volume: To understand the consumer, there should be a large volume of structured data in several environments.


    Velocity: A large amount of data should be processed, collected, analyzed, and interpreted at an incredible velocity.


    Variety: There should be a wide variety in the data because, without these varieties, the pattern and behaviorism cannot be predicted. 


    The other two Vs include veracity and value. 


    During the analysis process, the data holds no individual value - it is not helping you make predictions to improve overall operations. However, after the analysis, you get business-ready actionable insights that you can implement in real-world scenarios. This is big data's value. 


    Veracity denotes the accuracy of the big data. Companies must collect data from credible and reliable sources as inaccurate data will deliver erroneous results. Hence, it is crucial to verify the data's authenticity. 


    Recently a few more Vs have been added to the list, including variability, validity, volatility, and visualization. The meanings are self-explanatory.

    Why should we learn about Big Data?

    It is imperative to learn about Big Data, especially during a time when it is growing at a swift pace. The market size of Big Data is estimated to grow to $229.4 Million soon.

Thus, data management and handling are pivotal. Remember that adapting to the new changes and trends is one of the biggest aspects of data management.

    • Learning algorithms and getting handsy with them will improve your handling of big data.

    How to distinguish between traditional data and Big Data?

    There is a vast distinction between traditional data and big data. At the very beginning, something that helps with the distinction is the 5 Vs.


    Traditional data is generated per hour or daily, and different organizations, from smaller ones, maintain the collected structured data to bigger ones for business purposes. This data is processed and maintained by a centralized system. It is produced at a venture level, and its volume varies from gigabytes to terabytes. 


    On the other hand, big data is a more developed and higher version of traditional data. It can be structured, semi-structured, and unstructured and is processed outside the enterprise level. The range is from petabytes to zettabytes or exabytes. Its complex, massive nature makes it impossible to store it in a traditional system. Big data, unlike conventional, is generated every second.

    What are the advantages of Big Data?

    Traditional reporting provides an analysis that is insufficient in today's fast-moving world. Hence Big Data applications act as an advantage because systems that are made generate high-quality data, which allows for better consumer behavior prediction with good sources and evidence to back up.


    Here are some advantages of Big Data:

    • As digital footprint leaves behind patterns accumulated in big data, revealing a lot about a person's preferences. This opens up new opportunities for the organizations and helps improve efficiency, customer satisfaction, and horizons. It further opens up new avenues. For instance, shopping sites like Flipkart or Amazon use it to understand their customers' choices better, allowing them to put forward more personalized suggestions.

    • Big data gives organizations a better understanding of promoting products to a targeted audience during a specific time. This allows the companies to understand which customers would enjoy which campaigns, products, etc. 

    • Big data helps in improving efficiency and provides better communication with the customers. The feedback will act as a way to enhance potential defects, allowing companies to cater to customer needs better. 

    • Big data comes in handy in the healthcare industry as it understands a patient's medical history, allowing doctors to deliver targeted care and treatment. Big data apps can streamline the communication between healthcare professionals and patients, letting them access medical services promptly.

    Why is Big Data Important?

    Big Data helps in the improvement of the customer service that is being provided by organizations and helps to create a personalized marketing space. This allows businesses to earn benefits, profits, and an advantage over the competition and helps them grow faster by making decisions that will help them work all their way up.


    Big Data gives access to the companies and helps in refining and evolving in terms of marketing, advertising, and promotion, further enhancing the consumer's engagement with the company. For instance, Big Data is a major help in medical research as it helps identify the medical conditions very quickly and effectively. 


    Big Data modifies everyday living and helps find the best for an individual as it helps provide personalized suggestions. Most importantly, it helps the government identify a major emergency and helps prevent crimes or send help immediately in case of an emergency.

    How to use Big Data?

    Big data works in an algorithm that is done through machine learning. There are rules, data, and models that will be set. After drawing it over the machine learning tools, computer programs, and constant reprogramming, the model will keep improving until it offers the final product that matches the desired output. This change happens due to continuous behavioural change.


    For instance, if someone is buying tree ornaments, Big Data analytics will relate this to the fact that this pattern occurs t only during Christmas; hence, the sale of such ornaments is seasonal. So it would not be correct to suggest ornaments throughout the year, and the suggestions will be only applicable during that time of the year.


    Effective ways of using big data:

    • The technology being flexible is extremely important to suit the customers' needs. To make it perfect, there will be a constant need for improvement.

    • Using all kinds of platforms will be necessary as the customers themselves won't stick to a specific one.

    • Capture all the information you can get without leaving behind anything, as each part of it will offer you some kind of information or the other. And after the accumulation of big data, you can truly understand the behavior.

    • Checking the authenticity of the information is very important as without authenticity it will produce a wrong idea which will bring the incorrect information earnt do any good in terms of profit.

    • And finally, putting it to use after a lot of consideration of the big data analytics.

    How can we use Big Data to improve the business models and analyze the data?

    Living in an era where even the smallest tools in the house are mechanical and deliver impactful services. For instance, you can order a house to switch on or off applications just by using your voice. The data generated will be further used in marketing strategies targeted at different user personas.


    Big data is something that contributes to the economy on a huge scale. In this era, executing personalized marketing strategies for individual customers is extremely important. This will enhance one's business goals and create an enriching customer experience. 


    It is vital to improve and restructure the business models based on big data analytics results. Big data helps generate smarter, targeted consumer services, improving company ROI. Companies use big data to form strategies and build better products. 


    There are four types of big data business models:

    • Data users need data to create strategies for their businesses to build a product suitable for the users.

    • Data Suppliers are those who provide and trade the data.

    • Delivery Networks are the businesses that advertise business models.

    • Data Facilitators are involved in data collection, analysis, and management.

    What is the difference between data and Big Data?

    Something that marks the difference between data and Big data is the Vs. Data is a set of variables acquired through machines, structured and unstructured, and could be created and analyzed with traditional software.  


    On the other hand, big data is a massive amount of unstructured data that is constantly accumulated at a rapid pace. Here, conventional technologies and software do not help. This big data is so advanced that it can derive information through some of the most complex data samples.


    The biggest advantage of big data is understanding the pattern and finding the interdependence of different events in the world. Companies can use different algorithms to find solutions to business challenges and innovate.

    How can we store Big Data?

    All the data that is constantly getting generated from all types of sites or documents are getting stored in what is known as the data lake. A data warehouse can support only a specific type of data, but on the other hand, a data lake can support any data, and it is vastly based on each program. For example, big data Hadoop uses a distributed file system called "Hadoop distributed file system" to store big data. 


    This is because of the massive chunks of data being produced. Thus, it is broken down into smaller pieces in different machines. A duplicate copy is also created - so if one file gets corrupted or if one machine fails, you will always have a backup.


    The lengthy task is broken down into several smaller tasks, so different machines take up each task and complete it simultaneously. Later these tasks are put together to get the results. This makes the process easy and fast, and this way of storing is known as parallel processing.


    But several algorithms and systems are put work together to store big data. For instance, the data lake is connected with several other platforms like data warehouses. All this data that is getting accumulated is then organized, analyzed, and managed. 


    Then through data management, it gets processed depending on how it will be used. To generate and store Big Data, there are several minute details in the infrastructure that must be taken into consideration.

    How to retrieve data?

    Several scenarios could involve data loss, including deletion, formatting, corruption, crashing, or failure. But advanced technologies have made it easier to retrieve it back almost immediately. Systems like data recovery software are built to make it easier to bring the data that has been lost. Cloud is an effective location from which data can be stored and retrieved.

    Big data is unstructured, semistructured, and structured data that gets generated and processed every second someone uses a smartphone and invests their time in things like messages, media, phone calls, social apps, etc. Organizations then analyze and manage this data to offer better performances and services to their customers. It allows the creation of a more individualistic platform for every targeted audience.

    What are the 5 Vs of Big data?

    The five Vs that big data consist of are - 

    Volume: The amount of the data that is getting accumulated

    Velocity: At what speed, a certain amount of data is getting accumulated

    Variety: The variety in the data, including structured, unstructured, and semistructured data

    Veracity: The accuracy of the data

    Value: The part of the data that brings profit to the businesses

    What do you understand by the term big data Hadoop?

    Hadoop is one of the programs, and it and Big data go hand in hand as they almost are equivalent to each other. Hadoop is a big data specialized operation that has been recently on the rise and moving forward towards massive popularity. 

    Why is big data training essential?

    Big data training is important for getting a better job opportunity and contributing to a company's growth as it helps identify a customer's patterns which will result in profit. Hence, a certified data analytics course is recommended because extra knowledge never hurts; instead, it will land more job opportunities.

    How does Big Data help a business in terms of benefits?

    The analysis produced by big data enables businesses to create specific products. These products are highly dependent on the needs of each customer. This is possible because big data allows the company to follow the pattern of a customer, which helps them predict their preferences. It enhances the relationship between the retailer and the customers. This increases sales and benefits them in spreading good words about their business.

    What is big data in AI?

    Artificial intelligence is rapidly taking over our surroundings, thanks to rapid adoption. Human errors are avoided when AI is used. Traditional data was easier to process and could be done by humans. But the complex, massive and high-velocity datasets that are big data cannot just be done traditionally, adding to the influence of AI's decision-making. Due to its size, it can only be processed and analyzed for information in high-tech AIs.

    What problems would big data face if there were no distributed system concepts?

    The distributed computing system is the only way to help store such an enormous amount of data. If there were no concept of a distributed computing system, organisations would be forced to use computers with individual memories or would need to build a computer with enormous memory space capable of processing an exhausting amount of data. It will not only cost way much to make such a device but would not be practical to practice. Hence, most companies and individuals would have been deprived of utilising Big data. 

    Can I data mine Big data?

    The laws regarding data mining are different in different countries. The countries where government states that any individual or organisation with lawful access to material protected by copyright has the authority to carry out analysis without asking for permission from the copyright owner. Hence, before trying to mine data, you must have a sound understanding of the respective country’s legislation. 

    Why do Big data projects fail?

    A handful of reasons contribute to projects utilising the power of big data failing. Some main reasons include collecting the wrong data, not defining the problems they aim to solve, not having realistic goals and objectives on how to utilise the data, and lack of right talent for skilful data analysis. 

    Will Big data replace data warehouses?

    No. The major similarities between data warehouses and Big data are that they hold enormous data, are useful for reporting and are managed with the help of electronic storage devices. However, both have some significant differences and purposes. The primary difference is that the big data solution is technology; however, data warehousing is an architecture. Hence, it is evident that none of them can replace each other. 

    Is Big data analytics a good career?

    Big data is undoubtedly one of the fastest growing fields and holds exciting global opportunities. Opting for a career in Big data can offer a handsome salary. The average salary of a Data Scientist is around $100,000, and there is also a wide range of job roles in the field to choose from. 

    Does Big data processing require coding?

    Yes, coding is one of the top skills required for a Big Data analyst. A Big Data analyst needs to know coding in order to perform numerical and statistical analyses of huge data sets. Some of the programming languages in which you may invest your time and money would be Python, Java, R, and C++. If not all, you must learn Python, as it has a built-in feature of supporting data processing of unstructured types. 

    How is Big Data stored and managed in organisations?

    Companies and big organisations utilise distributed file systems to store the unstructured type of data. This file system further helps divide the large files into categorised data blocks. These data blocks are further distributed amongst the cluster nodes. The more similar blocks are formed, the number of nodes decreases. Organisations often use data lakes as well to store big data. 

    When is Big data used?

    Big data is currently being used in different industries such as healthcare, education, gambling, environmental protection, etc. apart from them. Big data is also used in different government sectors and entertainment industries as well. Different companies in these industries use big data to identify patterns and trends from the explosion of data. 

    Where to find Big data?

    Numerous free data sets available on the internet can be used for personal analysis. Big companies usually prefer to collect their own data and curate unique data sets from them. However, you can also check free sources such as Socrata, Google Trends, Facebook Graph, etc., to find data sets. 

    Which Big data technology is in demand?

    Big data technologies that are high in demand in 2022 include Artificial Intelligence, Machine Learning, SQL-based technology, Apache Spark, and more.  

    Which BIg data framework provides the most scalability?

    Frameworks based on the MapReduce model provide the most scalability for big data storing and processing. An example of such a framework is Apache Hadoop. It is also an open-source framework which is why it is even more prevalent. 

    Which database is best for Big data storage?
