Dynamic integrity constraints

Definition

Temporal integrity constraints are integrity constraints formulated over temporal databases. They can express dynamic properties by referring to data valid at different time points. This is to be contrasted with databases that do not store past or future information: if integrity constraints can only refer to data valid at the current time, they can only express static properties. Languages for expressing temporal integrity constraints extend first-order logic with explicit timestamps or with temporal connectives. An important question is how to check and enforce such temporal integrity constraints efficiently.

Historical Background

The use of first-order temporal logic for expressing temporal integrity constraints dates back to the early 1980s (see, e.g., [2]). Since the late 1980s, progress has been made in the problem of checking temporal integrity [3, 9, 11] without having to store the entire database history. This entry deals with...
