Biometric datum
* Biometric data are separate and distinct from personal information
  - is information about the physical make-up of the cardholder
+ Biometrics: Biology :: Computer science :: Authentication methods
  * When selecting features, those choosing must also look at social acceptance. Taking a fingerprint may be ok, taking a blood test may not be. Some biometric data is also easier to fake, e.g. signatures.

Current datum
* Current data show that vaccine-induced antibody levels decline gradually over time.
* Current data suggest that essentially all colorectal cancers originate from adenomatous polyps
  - modern humans evolved from archaic humans primarily in East Africa

Epidemiological datum
* Epidemiological data is information on transmissible diseases in the population.
* Epidemiological data show that cancer incidence increases exponentially when plotted against age
  - such patients are at increased risk for both stroke and heart attack
  - suggest antidepressants reduce suicide risk among depressives

Limited datum
* Limited data do suggest anthocyanins possess anticancer properties.
* Limited data indicate that caffeine has the potential to biodegrade in soil
  - the potential to biodegrade in water
  - mercury has accumulated in some fish
* Limited data suggest that imipramine is likely to be excreted in human breast milk
  - thioridazine is likely to be excreted in human breast milk
  - zotepine is an antipsychotic, at least as effective as typical drugs

Molecular datum
* Molecular data facilitate a reevaluation of traditional tenets of polyploid evolution
  - form the heart of genetics and subsequently evolution
  - show that archaebacteria and eukaryotes share a more recent common ancestor
* Molecular data suggest an early acquisition of the mitochondrion endosymbiont
  - that whales and dolphins evolved from hippo-like ancestors

### message | information | datum:

Personal datum
* Personal data can also include sound, digital photographs and images
  - includes an expression of opinion about an individual
* Personal data is data about an identified or identifiable individual that is recorded in any form
  - information about living, identifiable individuals
  - the responsibility of each user to back up on their own
  - relates to living individuals who can be identified from that data
  - unit of exchange that is openly monitored and used to increase power

Recent datum
* More recent data indicate that sleep, like consciousness, is an active process.
* Recent data indicate that significant neurogenesis takes place even in the adult human brain
  - show that the hibernation period for some animals is becoming shorter
  - show, however, that phytochrome has another role during the life span of higher plants

Scientific datum
* Scientific data are our best understanding of truth.
* Scientific data is found in the form of variables
  - important to policy making
  - the lifeblood of all research activity
  - shows the correlation of wave shapes with aura color
  - suggest that vegetarians have reduced risks for several degenerative diseases

### message | information | datum:

Spatial datum
* Spatial data are the coordinates of the spatial information
  - describes where map features are, whereas attribute data describe what they are
* Spatial data is data pertaining to the location and spatial dimensions of geographical entities
  - modeled in layers, all defined by the same object space and coordinate system
  - stored in a digitized computer file
  - used in a wide variety of economic, social and environmental applications
  - relate to the location and movements of a player
