    Abstract : For growing organisations that have built their data flow around a monolithic database server, anever-increasing number of applications and an ever-increasing demand for data freshness willeventually push the existing system to its limits, prompting either hardware upgrades or anupdated data architecture. Switching from an approach of full extractions of data at regularintervals to an approach where only changes are extracted, resource consumption couldpotentially be decreased, while simultaneously increasing data freshness.

    Abstract : Approximately 40% of the total energy consumption within the EU is due to buildings, and similar numbers can be found in the US. If the principal inefficiencies in buildings were easily identifiable, then a facility manager could focus their resources to make the buildings more efficient, which would lead to both cost savings for the facility owners and decrease the building’s ecological footprint.
