archaeological data
SYNONYMS OR RELATED TERMS: archeological data

data
SYNONYMS OR RELATED TERMS: sing. Datum
CATEGORY: technique
DEFINITION: Relevant observations made on artifacts, serving as the basis for study and discussion. Factual information (as measurements or statistics) used as a basis for reasoning, discussion, or calculation.
data acquisition
CATEGORY: technique
DEFINITION: A stage in archaeological research design in which data are gathered, normally by three basic procedures -- reconnaissance, surface survey, and excavation.
data cluster
CATEGORY: technique
DEFINITION: Archaeological data found in association and in primary context and used to define areas and kinds of ancient activity. Such information may be divided into composite, differentiated, and simple data clusters.
data dictionary
CATEGORY: database design
DEFINITION: Documentation of all the files, fields, relations, and processes used in a database.
data pool
CATEGORY: technique
DEFINITION: The archaeological evidence available within a given data universe, conditioned by both behavioral and transformational processes.
data processing
CATEGORY: technique
DEFINITION: A stage in archaeological research design usually involving, in the case of artifacts, cleaning, conserving, labeling, inventorying, and cataloging.
data universe
CATEGORY: technique
DEFINITION: A defined area of archaeological investigation, bounded in time and space, often a geographic region or an archaeological site.
data-flow diagram
CATEGORY: database design
DEFINITION: A logical model of an information system depicting its entities, processes, and flow of data between processes.
database
CATEGORY: database design
DEFINITION: A compilation or storage system for information that is used for decision-making, inferences, interpretation, and testing hypotheses.
differentiated data cluster
CATEGORY: technique
DEFINITION: A method of clustering data that are heterogeneous and patterned in regard to two or more activities reflective of age or sex differences; e.g., a house floor with cooking utensils and hunting weapons in primary context.
flat-file database
CATEGORY: database design
DEFINITION: A set of data records stored in a single large table.
interval data
CATEGORY: term
DEFINITION: Any data that has categories that are ordered and have a constant interval between each category.
isolated data
CATEGORY: artifact
DEFINITION: A single object that is found without association to any other artifact or feature; typically lost during travel or moved by a relic hunter. Any unassociated archaeological remains.
off-site data
CATEGORY: term
DEFINITION: Unclustered physical remains produced by human activities; evidence from a range of information, including scatters of artifacts and features such as plowmarks and field boundaries. This data can provide important evidence about human exploitation of the environment.
Phase III data recovery
SYNONYMS OR RELATED TERMS: Phase III
CATEGORY: technique
DEFINITION: An excavation of an historic or archaeological site listed or eligible for listing on the National Register of Historic Places prior to its demolition for new construction.
relational database
CATEGORY: database design
DEFINITION: A structured system of data files organized by controlled redundancy (key attributes and attribute pointers).
sample data acquisition
CATEGORY: technique
DEFINITION: Investigation of only a portion of the sample units in a population, by either probabilistic or nonprobabilistic sampling.
simple data cluster
CATEGORY: technique
DEFINITION: Clustered data that are homogeneous in that they have a single function, such as those from an obsidian tool workshop.
total data acquisition
CATEGORY: technique
DEFINITION: The investigation of all sample units in a population.
