Datapositions
Datapositions is a term used in data modeling and computer storage to describe the predefined physical or logical positions of data elements within a data structure or binary format. In this concept, each field occupies a fixed offset or a fixed sequence within a record, and accessing the field is determined by its position rather than by inspecting its value alone.
The idea is most often encountered in fixed-length records, legacy binary file formats, or compact in-memory
Datapositions are relational to, but distinct from, data semantics. They complement a schema by describing where
Advantages of using datapositions include fast, deterministic access when formats are stable and well defined. Limitations
