| Abstract: | In search of the appropriate semantics for the inclusion of structures
and operations that will meet the needs of a wide class of users
interested in a database system supporting temporal views of their data,
the paper includes a discussion of many problems that must be addressed.
Salient features of the authorâs Historical Relational Database
Model (HRDBM) are presented, and some subtle nuances that time brings to
the development of an historical relational algebra are illustrated.
Along the way, a number of observations and guidelines are presented
that may help guide the search for an historically relationally complete
database model and query languages. |
