has_specified_input has specified output has_specified_output completely executed planned process information content entity database extract, transform, and load process WEB:https://en.wikipedia.org/wiki/Extract,_transform,_load Alan Ruttenberg 12/21/16: Maybe this definition instead: A planned process which takes as input a database and copies concretizations from the first, optionally transforms then copies the result to the second A planned process which takes as input a database and fills another database by extracting concretizations of information entities from the first, transforming them, and loading the transformed concretizations into the second. Alan Ruttenberg 12/21/16: We don't define database in IAO, currently, as the bare word is ambiguous. Reasonable interpretations of the word might be the material entity, an information structure, an information content entity. However this definition commits, at least, to there being some material thing which bear concretizations of information entities and that there are new concretizations created during the process. We consider the ETL process in terms of information entities rather than the concretizations. No committment is made as to whether the specified output.
