What is big data

This includes places like smartphones, in-house devices, social media chatter, stock ticker data, and data from financial transactions. The source has to be particularly relevant to the nature of the business for which the data is being collected. For example, a retail company must be tuned in to what users are saying on social media about its recently launched clothing line.

A manufacturing company would less embedded value in following social media. A variety of data can also extend to help organizations with understanding customer profiles and personas. For instance, a company would find it helpful to know not just how many people open their newsletter, but also why they opened it and distinguishing characteristics of the audience.

Veracity calls into question the quality and accuracy of data. Clean data is the most trustworthy. Organizations must connect, cleanse, and transform their data across systems in order to trust it. They need hierarchies and multiple data linkages to keep control of their data.

At the apex of the pyramid sits value, the ability to extract viable business insights from within the avalanche of data. Value is being able to predict how many new members will join the website, how many customers will renew insurance policies, how many orders to expect, and such. Companies gain value through their ability to monetize the insights provided by big data.

They get to know their customers better and continue to make more relevant offerings. This is the data that comes from the Internet of Things and connected devices. It is data that flows into systems in chronological order.

It can stream into IT systems from a multitude of connected gadgets such as smartphones, wearables, smart cars, industrial equipment, and medical devices. Streaming data can be analyzed on a first-in or continuous basis, scanning it to see if it is worth storing for further analysis, or whether it can be safely discarded. The millions of daily interactions on social media platforms such as Facebook, Instagram, YouTube in the form of pictures, images, GIFS, videos, voice, comments text and sound files make up the repertoire of social media data.

This is especially valuable for sales, support, and marketing campaigns. The challenge lies in the fact that it is mostly in unstructured or semi structured form, so additional processing is needed before it can be analyzed. This refers to the enormous number of open data sources including data.

Processing big data begins with setting up a strategy to harness it. The next step is to identify and catalog its sources, locations, systems, users, and owners and how it flows in. Then create an infrastructure to store and manage the data to be readily accessible for analysis, the final step to facilitate data-driven decision making. This protocol is useful to manage traditional structured datasets as well as unstructured and semi structured data. When developing a big data management strategy, it is imperative to factor in current and future business goals from a business growth as well as technology standpoint, and treating big data just like any other business asset of value.

Data can be stored either onsite in a traditional data warehouse, but cloud storage solutions have gained popularity in recent years. These are more economical and provide a certain degree of flexibility.

Where processing is concerned, computing systems available today are equal to the speed, power, and agility necessary to meet the demands of accessing such massive data volumes. Integrating data, ensuring quality control, providing data governance and readying it for analytical tools to do their job are also necessary parameters.

Big data is what fuels the advanced analytics endeavors of our era, such as artificial intelligence. The more efficiently a company uses its collected data, the more potential it can extract out of it. Investing in software that can manage and analyze huge volumes of data, particularly in real time, is a vital step to big data management. MapReduce, BigTable, and Hadoop: When large amounts of data are to be stored, and better or more efficient ways of conducting business activities are to be identified, tools like Hadoop and cloud-based analytics are tapped.

These help in optimizing processes to deliver cost advantages. Furthermore, the high speed of tools such as Hadoop coupled with in-memory analytics helps identify untapped resources, i. The speed of capturing and analyzing data is a great asset for companies to make quick decisions. Complex challenges need clever solutions.

Platforms need to empower organizations with intuitive, simple interfaces that ensure even the least IT-savvy can use them. The platform should also be able to leverage the full spectrum of big data, resulting in accurate, real-time analytics. What it is and why it matters. Variability In addition to the increasing velocities and varieties of data, data flows are unpredictable — changing often and varying greatly. Veracity Veracity refers to the quality of data.

How Big Data Works Before businesses can put big data to work for them, they should consider how it flows among a multitude of locations, sources, systems, owners and users.

Set a big data strategy. Identify big data sources. Access, manage and store the data. Analyze the data. Make intelligent, data-driven decisions. You can analyze this big data as it arrives, deciding which data to keep or not keep, and which needs further analysis. Social media data stems from interactions on Facebook, YouTube, Instagram, etc. This includes vast amounts of big data in the form of images, videos, voice, text and sound — useful for marketing, sales and support functions.

This data is often in unstructured or semistructured forms, so it poses a unique challenge for consumption and analysis. Other big data may come from data lakes, cloud data sources, suppliers and customers. Next Steps Big data demands sophisticated data management technology to transform your analytics and AI programs into big opportunities.

Article Connected vehicles: IoT steers a new direction for OEMs With IoT and analytics, automakers and their partners can reshape business models, find new ways to monetize data and serve customers better. Big data refers to massive complex structured and unstructured data sets that are rapidly generated and transmitted from a wide variety of sources. These attributes make up the three Vs of big data :. These days, data is constantly generated anytime we open an app, search Google or simply travel place to place with our mobile devices.

The result? Massive collections of valuable information that companies and organizations need to manage, store, visualize and analyze. Traditional data tools aren't equipped to handle this kind of complexity and volume, which has led to a slew of specialized big data software and architecture solutions designed to manage the load. Big data is essentially the wrangling of the three Vs to gain insights and make predictions, so it's useful to take a closer look at each attribute.

Big data is enormous. While traditional data is measured in familiar sizes like megabytes, gigabytes and terabytes, big data is stored in petabytes and zettabytes. To grasp the enormity of the difference in scale, consider this comparison from the Berkeley School of Information : one gigabyte is the equivalent of a seven minute video in HD, while a single zettabyte is equal to billion DVDs.

This is just the tip of the iceberg. According to a report by EMC, the digital universe is doubling in size every two years and by is expected to reach 44 trillion zettabytes. Big data provides the architecture handling this kind of data. Without the appropriate solutions for storing and processing, it would be impossible to mine for insights.

From the speed at which it's created to the amount of time needed to analyze it, everything about big data is fast. Some have described it as trying to drink from a fire hose. Companies and organizations must have the capabilities to harness this data and generate insights from it in real-time, otherwise it's not very useful. Real-time processing allows decision makers to act quickly, giving them a leg up on the competition.

While some forms of data can be batch processed and remain relevant over time, much of big data is streaming into organizations at a clip and requires immediate action for the best outcomes. Sensor data from health devices is a great example. The ability to instantly process health data can provide users and physicians with potentially life-saving information. Everything from emails and videos to scientific and meteorological data can constitute a big data stream, each with their own unique attributes.

The diversity of big data makes it inherently complex, resulting in the need for systems capable of processing its various structural and semantic differences.

Big data requires specialized NoSQL databases that can store the data in a way that doesn't require strict adherence to a particular model. This provides the flexibility needed to cohesively analyze seemingly disparate sources of information to gain a holistic view of what is happening, how to act and when to act. When aggregating, processing and analyzing big data, it is often classified as either operational or analytical data and stored accordingly.

Operational systems serve large batches of data across multiple servers and include such input as inventory, customer data and purchases — the day-to-day information within an organization. Analytical systems are more sophisticated than their operational counterparts, capable of handling complex data analysis and providing businesses with decision-making insights. These systems will often be integrated into existing processes and infrastructure to maximize the collection and use of data.

Regardless of how it is classified, data is everywhere. Big data is used in nearly every industry to identify patterns and trends, answer questions, gain insights into customers, and tackle complex problems. Companies and organizations use the information for a multitude of reasons like growing their businesses, understanding customer decisions, enhancing research, making forecasts and targeting key audiences for advertising. Here are a few examples industries in which the big data revolution is already underway :.

The finance and insurance industries utilize big data and predictive analytics for fraud detection, risk assessments, credit rankings, brokerage services and blockchain technology, among other uses. Financial institutions are also using big data to enhance their cybersecurity efforts and personalize financial decisions for customers.

Hospitals, researchers and pharmaceutical companies are adopting big data solutions to improve and advance healthcare. If you've ever used Netflix, Hulu or any other streaming services that provide recommendations, you've witnessed big data at work.

Media companies analyze our reading, viewing and listening habits to build individualized experiences. Netflix even uses data on graphics, titles and colors to make decisions about customer preferences. From engineering seeds to predicting crop yields with amazing accuracy, big data and automation is rapidly enhancing the farming industry. With the influx of data in the last two decades, information is more abundant than food in many countries, leading researchers and scientists to use big data to tackle hunger and malnutrition.

Data collection can be traced back to the use of stick tallies by ancient civilization when tracking food, but the history of big data really begins much later.
