Data Embodiment – an Ecosystemic Approach

Embodiment is comparable to the idea of an “ecosystemic” or “holistic” approach. In an ecosystem, each thing affects everything else.

Instead, there is a need to bring together many aspects of the body. To understand embodiment, it is necessary to recognize how “the body” separates an organism from its environment; in a manner of speaking, the body represents…

esProc Helps Database realize Real-time Big Data computing

The Big Data Real-time Application is a scenario to return the computation and analysis results in real time even if there are huge amount of data. This is an emerging demand on database applications in recent years.

At least, if going in that direction, hire someone favoring simple, scalable, robust, automated solutions over anything else. To automate, you need someone great at developing…
