Hamid and collaborators define data as similar if they are from the " same underlying source" (e.g. all gene expression) and as heterogeneous if at least two fundamentally different data sources are involved (e.g. SNP and gene expression).
We detected similar life-history trends in this phylogenetically defined data set as were shown above for the full set of 63 species.
As we sampled participants from different studies, we defined data saturation as no new motive emerging over all studies.
We defined data latency as the average hop-count a packet originating at a sensor node travels to reach to the corresponding sink.
We define data producers as researchers and also those who design and manage information systems, such as monitoring and evaluation (M&E) specialists.
We define data copy as follows.
Dhar (2013) defines data science as the study of the generalizable extraction of knowledge from data.
They define data completeness as the fraction of patients that has some value documented for a given patient characteristic.
Most REST services define data formats [13] as a means for communication, rather than an explicit data model.
In 2010, Apache Hadoop defined big data as 'the data sets that could not be captured, managed and processed by general computers within an acceptable scope' [20].
