Understanding the Past to Predict the Future

Internet of Things (IoT), Big Data and Business Intelligence (BI) are very hot topics at the moment everybody is talking about. All of these trends are interesting for themselves as they promise deeper insides into a business and therefore lead to better business decisions. Internet of Things enables businesses to gather data and to control […]

3 Articles in the upcoming Business Technology Magazine

At the moment digitalization and IoT are taking off and belong to the hottest trends in information technology. Because of the experience OC has in Business Intelligence, Integration and Software Development we were able to publish 3 articles in the upcoming Business Technology, which is completely issued for the Internet of Things. The articles are: […]

iot-toolkit.net went live

A little spin off of the cattle crew blog just went live: iot-toolkit.net The purpose of the website is to collect articles, talks and other information with a strong IoT background and to give interested persons a focused overview over the topics. However, blogging is still done here;-)

Quick thought: Develop Software on embedded device using IntelliJ

Last week I had to develop a quick prototype on a raspberry pi. A nodeJS app that counts pulses from a liquid throughput sensor which forwards the data to a SAP Hana backend. Using a software mock for my sensor only helped until a certain point. In the end I had to test the actual sensor […]

IoT prototype – low-level thoughts about camunda BPM and Drools Expert (part 6)

As already mentioned in the second part of this series, building systems of this type consists of several components. In this part we describe the integration of a BPMN 2.0 capable workflow management system and a business rule engine in our IoT prototype. Why do we need such things Currently we live in times of a knowledge society […]

IoT prototype – Retrospective. What did we learn? What did we miss? (part 5)

Okay so controlling our lights now works automatically based on entering and leaving the building, thats great! But what did we learn from all this? What do we believe can be transferred to a general concept found in (almost) all possible IoT projects?   What did we learn? Communication takes more than one way Meaning, […]

IoT prototype – low-level thoughts about the 433mhz communication (part 4)

This prototype started off as a personal project. So it’s not a big surprise why the 433mhz plugs were chosen as a first tech. They are in every household and I wanted to retrofit what was already there to become a bit smarter. Being able to group, manage and remotely control these plugs is an […]

IoT prototype – low level thoughts on Oracle CEP Embedded (part 3)

In our prototype we used an Oracle CEP Embedded application running on a separate Raspberry Pi to scan the network for arriving / leaving devices and link them to our users. We could have left this logic in our Spring server and have it running in our service layer but we wanted to learn more about […]

IoT prototype – an architectural overview (part 2)

With our prototype we had a few goals: learn about the technologies that are involved in the IoT space Follow a good architectural principle get the attention (and trigger their curiosity) of visitors at different events Of course there were also the functional requirements of being able to effectively know when a user is present or […]
