In computing, an abbreviation for 'dataset,' a collection of related data organized together; commonly used in mainframe and database systems.
Abbreviation formed by taking the first letters or syllables of 'data' (DT for 'dat') and 'set,' reflecting the compressed naming conventions of early computing when systems had strict character limitations.
DTSET is the kind of abbreviation that only makes sense if you squint at the letters sideways—it shows how computer scientists often compressed words in ways that don't follow normal abbreviation rules, creating specialized dialects that exclude outsiders.
