OLAP and Hadoop: A Great Pairing
OLAP continues to be a relevant and exciting technology, most recently in pairing OLAP and Hadoop. As we are OLAP.com, we have ALWAYS seen the value of OLAP technology. We admit OLAP has been a bit out of style the last few years. Some companies even run Google ads about how “OLAP is obsolete,” but nothing could be further from the truth. (Check out our blog on that one.)
We see this in the fashion industry all the time: what is old is new again! This is rare in the technology realm, but it seems to be the case with OLAP. As developers struggle to get value out of Hadoop data, they discovered they needed the speed and flexibility of OLAP. OLAP and Hadoop is a powerful combination for getting to the ultimate goal of extracting value from Big Data.
Bringing OLAP to scale for Big Data
In an article from ZDNet, Is this the age of Big OLAP? Andrew Brust writes about the new relationship between OLAP and Hadoop. He highlights that OLAP technology can be particularly beneficial when working with extremely large Big Data sets. Typically, OLAP has not been scalable enough for Big Data solutions. But OLAP technology continues to progress, we find this new application of OLAP exciting. Brust discusses a few strategies for bringing the two technologies together. He mentions a few OLAP vendors in detail and how they manage the issue of scalability for OLAP software.
If you want to try using OLAP with Hadoop, perhaps you want to give PowerOLAP, the mature OLAP product of OLAP.com, a try? There is a free version of PowerOLAP available. If you plan to test PowerOLAP with your Hadoop, contact PARIS Tech, and they will lift the member limit for you in the free version, as you will need to go beyond the member limit that ships with the free version.
In sum, OLAP.com is pleased to see OLAP rising in relevance once again and getting some of the recognition we felt it deserved all along. It is a testament to the power and value OLAP has as a technology.
So, you have made the decision to dive into the world of IoT and Big Data? Where to start is the major question and can seem overwhelming. Preston Gralla has come up with some key steps in making the decision or updating your current solution program in his article, 6 Tips for Working with IoT and Big Data.
- The first clear way to dive in is to know the problem you are facing and what the end result looks like to you. Without a crystal clear picture of what you have to solve, a project can easily head in a different direction or take longer than expected to go into implementation.
- Then, you must deploy the “right people” on the project. Gralla states that Data scientists can be expensive to employ and hard to come by, because, today, they are so much in demand. Instead he suggests that you seek the resources within your company. Employees with the Big Data and IT experience may have the drive and motivation to learn new techniques in order to take on new projects.
- Next, Gralla talks about how important it is to know exactly which data you will collect and also how it will be stored. In order to get the most from your analytics, it is important to be working with precise data that will give you the most accurate results and ROI.
- Data can be made up of complex layers and other times, it can be a simple layer of information. To ensure that it will work compatibly with each other, Gralla suggests that businesses build an extra abstract layer to allow room for extra layers of data that you may encounter along the way.
- The fifth tip that Gralla suggests, has to do with the platform. A large data analytic platforms can be very expensive and take extra time to develop. It may be the most efficient to invest in an outside platform for analytics and even maybe a cloud-based system.
- And finally, the last bit of advice when tackling Iot and Big Data is to start with a manageable size and continue to grow from there. Many businesses will take on too much at one time and struggle to succeed at them. Instead, start small so that you can manage to smooth out any errors along the way before taking on more.

As I think most of us would agree, Big Data has made big leaps in providing the business world with a large advantage. Luc Burgelman does a great job of identifying the three hurdles that he believes are holding businesses back from reaping the most benefit from their Big Data, in his article.
The first hurdle Burgelman refers to is the ability to evolve. He brings up a great point, companies are looking for different things than they were just two years ago. They need to take technology further than before to accomplish what they need as a final result. Also, companies need to be able to engage different/more departments in the analytical process. It is no longer just about the IT team. Other departments have valuable assets to add to the equation of data anaylsis, and we have to be open to sharing the data across the departments and company, taking a more well-rounded approach to tackling large analytical processes. Which leads smoothly into Burgelman’s second point…
Not only is it important to be involving more of the company’s departments, but we need to make sure that the C-level Executives are equally “on-board.” Let’s face it, without their their final “blessing,” no data technology plan will hit the ground running and be successful. Executives need to be equally passionate about the technology and understand the great benefit and ROI of the analytics behind the data.
The third hurdle that Burgelman talks about is changing the mindset of not only the C-level executives but of all who work directly with the data such as the data users and data scientists. Big Data and the technology behind it is a game changer and offers greater benefits to customers, which returns in greater customer loyalty and greater sale margins. Companies need to be able to change and progress with the latest technologies and analysis software to be able to change the way people and businesses make their decisions and interact with their data. So what do you think, are these hurdles something that we can get over and allow businesses to run faster.

One thing is certain, if you want to run a successful business, you need to hire the right people to help you get there. Who is in charge of recruiting and hiring your team members? “DING, DING, DING!” you guessed it, Human Resources. Human Resources is beginning to pull ahead in the Business Analytics world. In a “Big Data” world, HR can use “People Data” to their advantage and help businesses develop strategy when it comes to hiring the best candidates. As David Klobucher writes in his article, “Data-driven confidence will help HR professionals identify behaviors and interview styles that attract better employees, as well as qualities that make effective workers – and lead to faster promotions.”
I agree with Klobucher, this is a great time to be in HR. There are big opportunities that may be presented to anyone working in HR. Executives within businesses are looking to their Human Resources department to help build the strategy to success. Of course this all depends on if HR professionals “welcome” the technology with warm arms. As stated in the article, many individuals working with Human Resources are not completely comfortable using data just yet. In today’s world, Big Data surrounds all of us, but for HR, this can lead to big success from analyzing data of past successes and past failures.
In some HR departments, to take on this scope of technology could be intimidating, however like one of my favorite sayings goes, “I never said it would be easy, I only said it would be worth it.”
