The term big data started to show up sparingly in the early s, and its prevalence and importance increased exponentially as years passed. Nowadays big data is often seen as integral to a company's data strategy. Big data has specific characteristics and properties that can help you understand both the challenges and advantages of big data initiatives.

You may have heard of the three Vs of big data, but I believe there are seven additional important characteristics you need to know. Conveniently, these properties each start with v as well, so let's discuss the 10 Vs of big data. Volume is probably the best known characteristic of big data; this is no surprise, considering more than 90 percent of all today's data was created in the past couple of years.

The current amount of data can actually be quite staggering. Here are some examples:. As the same photo usually has multiple instances stored across different devices, photo or document sharing services as well as social media services, the total number of photos stored is also expected to grow from 3. That's 6.

What Is Big Data?

Sure, it sounds impressive that Facebook's data warehouse stores upwards of petabytes of databut the velocity at which new data is created should be taken into account. Facebook claims terabytes of incoming data per day. Google alone processes on average more than " 40, search queries every second ," which roughly translates to more than 3. When it comes to big data, we don't only have to handle structured data but also semistructured and mostly unstructured data as well. As you can deduce from the above examples, most big data seems to be unstructured, but besides audio, image, video files, social media updates, and other text formats there are also log files, click data, machine and sensor data, etc.

Variability in big data's context refers to a few different things. One is the number of inconsistencies in the data. These need to be found by anomaly and outlier detection methods in order for any meaningful analytics to occur. Big data is also variable because of the multitude of data dimensions resulting from multiple disparate data types and sources. Variability can also refer to the inconsistent speed at which big data is loaded into your database.The volume of data that one has to deal has exploded to unimaginable levels in the past decade, and at the same time, the price of data storage has systematically reduced.

The challenge of this era is to make sense of this sea of data. This is where big data analytics comes into picture. Big Data Analytics largely involves collecting data from different sources, munge it in a way that it becomes available to be consumed by analysts and finally deliver data products useful to the organization business. The process of converting large amounts of unstructured raw data, retrieved from different sources to a data product useful for organizations forms the core of Big Data Analytics.

Big data can be analyzed for insights that lead to better decisions and strategic business moves. The act of accessing and storing large amounts of information for analytics has been around a long time. Volume : Organizations collect data from a variety of sources, including business transactions, smart IoT devices, industrial equipment, videos, social media and more.

In the past, storing it would have been a problem — but cheaper storage on platforms like data lakes and Hadoop have eased the burden. Velocity : With the growth in the Internet of Things, data streams in to businesses at an unprecedented speed and must be handled in a timely manner. RFID tags, sensors and smart meters are driving the need to deal with these torrents of data in near-real time.

At SAS, we consider two additional dimensions when it comes to big data:. In addition to the increasing velocities and varieties of data, data flows are unpredictable — changing often and varying greatly. Veracity refers to the quality of data. Businesses need to connect and correlate relationships, hierarchies and multiple data linkages.

Otherwise, their data can quickly spiral out of control. At USG Corporation, using big data with predictive analytics is key to fully understanding how products are made and how they work.

The 4 V’s of Big Data

The data may be left in its raw form in big data systems or preprocessed using data mining tools or data preparation software so it's ready for particular analytics uses. Using customer data as an example, the different branches of analytics that can be done with the information found in sets of big data include the following:.

Volume is the most commonly cited characteristic of big data. A big data environment doesn't have to contain a large amount of data, but most do because of the nature of the data being collected and stored in them. Clickstreams, system logs and stream processing systems are among the sources that typically produce massive volumes of big data on an ongoing basis.The healthcare system is not only one of the largest industries. It is also one of the most complex, with patients constantly demanding better care management.

The industry is making rapid progress. Specialists seek more effective solutions and new technologies are frequently brought to the table. Big data in the healthcare industryalong with industry analytics have made a mark on healthcare. How is Big Data impacting the field? How is it supporting healthcare organizations and how could the entire industry actually benefit from these initiatives?

The following information focuses on a few relevant connections on the matter. While higher costs emerge, those patients are still not benefiting from better outcomes, so implementing a change in this department can revolutionize the way hospitals actually work. When all records are digitalized, patient patterns can be identified more quickly and effectively. ER visits have been reduced in healthcare organizations that have resorted to predictive analytics.

Supporting that permits a decrease in emergency situations. Checking on patients with high risk problems and ensuring a more effective, customized treatment approach can thus be facilitated. Lack of data makes the creation of patient-centric care programs more difficult, so one can clearly understand why utilizing big data initiatives can be so highly important in the industry.

The monitored results obtained on a regular basis enable healthcare facilities to try keeping people out of the hospital.By Jason Williamson. The general consensus of the day is that there are specific attributes that define big data. You might consider a fifth V, value. It makes no sense to focus on minimum storage units because the total amount of information is growing exponentially every year. For that same year, EMC, a hardware company that makes data storage devices, thought it was closer to exabytes and would grow by 50 percent every year.

No one really knows how much new data is being generated, but the amount of information being collected is huge. Variety is one the most interesting developments in technology as more and more information is digitized. Traditional data types structured data include things on a bank statement like date, amount, and time. These are things that fit neatly in a relational database. Unstructured data is a fundamental concept in big data.

The best way to understand unstructured data is by comparing it to structured data. Think of structured data as data that is well defined in a set of rules. For example, money will always be numbers and have at least two decimal points; names are expressed as text; and dates follow a specific pattern. With unstructured data, on the other hand, there are no rules. A picture, a voice recording, a tweet — they all can be different but express ideas and thoughts based on human understanding.

One of the goals of big data is to use technology to take this unstructured data and make sense of it. For one company or system, big data may be 50TB; for another, it may be 10PB. Veracity refers to the trustworthiness of the data. Can the manager rely on the fact that the data is representative? Every good manager knows that there are inherent discrepancies in all the data collected. Velocity is the frequency of incoming data that needs to be processed.

A streaming application like Amazon Web Services Kinesis is an example of an application that handles the velocity of data. Will the insights you gather from analysis create a new product line, a cross-sell opportunity, or a cost-cutting measure?

Or will your data analysis lead to the discovery of a critical causal effect that results in a cure to a disease? The ultimate objective of any big data project should be to generate some sort of value for the company doing all the analysis.
