Matthew, (02)
How about the following, which distinguishes: (03)
1. Application that provides management services
2. Document comprised of content (data). (04)
Thus, we end up with A DBMS (Database Management System) being an
application that provides Data Management (import, indexing, querying,
export etc..) services (driven by its supported model) scoped to
Document(s) [which may be internal or external] comprised of structured
data -- represented using a variety of notations. (05)
Which also implies that a Knowledge Management system just another kind
application with additional capabilities e.g., reasoning and inference. (06)
In both cases, if relational in orientation, these applications group
tuples as Relational Tables and/or Relational Predicate/Property Graphs. (07)
