Data-centric approach

We are about to enter what is, to many, a mysterious world—the world of factor spaces and the factor based techniques, Principal Component Analysis (PCA, sometimes known as Factor Analysis) and Partial Least-Squares (PLS) in latent variables. Our goal here is to thoroughly explore these topics using a data-centric approach to dispell the mysteries. When you complete this chapter, neither factor spaces nor the rhyme at the top of this page will be mysterious any longer. As we will see, it s all in your point of view. 

A behavior-centric and data-centric approach Previous methods, such as OMT, have been criticized by behaviorists for what is perceived as a data-centric approach. In Catalysis the two views support each other simply. You describe the behavior of a component in terms of attributes that relate to the clients concerns rather than any implementation. 

Sensors deliver a continuous range of values and often exhibit a subtle behaviour in case of external or internal disturbances. In our work, we use a data centric approach [4] to identify sensor failures, i.e. we try to infer faulty sensor data from... 

Multi-static radar is usually combined with the net-centric approach to data exchange. All sensor sites have to be connected by high-throughput, self-configuring data links. The data links should also provide a very stable clock to make all processing coherent, and very accurate time data to synchronize all events in the distributed system. 

So what is the solution If the mountain cannot go to Mohamed, Mohamed should go to the mountain. That is the data-centric computing approach. We leave the data where it is. Instead, we send the programs to go out and work on the data at their home site, where data are more secure, and to send back only the findings from the analysis, which are usually vastly smaller than the data. 

Object-oriented modeling can be divided into two schools data-centric design and problem-centric design. The problem-centric approach is being used in this work to focus on the problem at hand and move towards the solution. Figure 6-1 shows the overall framework of the modeling approach. The analysis part starts with contextual... 

The graphical user interface must allow role-centric subsets according to specialized user profiles, like CAD engineer, PLM data manager, controller, project manager. A one-size-fits-all approach tends to be too heavyweight for the majority of the users and will reduce the number of potential or satisfied users.
