Temporal Compatibility

  • Reference work entry
Encyclopedia of Database Systems

Definition

Temporal compatibility captures properties of temporal languages with respect to the nontemporal languages that they extend. Temporal compatibility, when satisfied, ensures a smooth migration of legacy applications from a non-temporal system to a temporal system. Temporal compatibility dictates the semantics of legacy statements and constrains the semantics of temporal extensions to these statements, as well as the language design.

Historical Background

Since the very early days of temporal database research, the compatibility with legacy languages and systems has been considered, but the first comprehensive investigation was reported by Bair et al. [2]. Compatibility issues are common for work done in the context of systems and commercial languages, such as SQL or Quel. Theoretical or logic-based approaches usually do not explore compatibility notions since they tend to strictly separate temporal from nontemporal structures.
