Data, Information, Evidence, and Knowledge: A
Comparison
o
Data—are raw observations (e.g., a measurement) of some reality,
whether past, current, or future, in a shared understanding of an
organizational context.
o
Information—is data placed in a context for use that has meaning
about a world we share.
o
Evidence—is information that makes sense (perhaps corroborated);
hence, it is something we can use to make reasoned thought
(argument) about the world.
o
Knowledge—is an assemblage of synthesizing, enduring, credible, and
corroborated evidence.

Define attribute database structure and behaviour for feature classes. Apply
subtypes to control behaviour, create relationships with rules for association,
and classifications for complex code domains.
Define spatial properties of datasets. Specify rules to compose topology that
enforces spatial integrity and shared geometry, and networks for connected
systems of features. Topological and network rules are set to operate on
features and objects. Set the spatial reference system for the dataset. Specify
the survey datasets, if needed. Specify the raster datasets as appropriate.
