| Descripción |
This paper describes a model of persistence in (C)LP languages and two di#erent and practically
very useful ways to implement this model in current systems. The fundamental idea is that
persistence is a characteristic of certain dynamic predicates (which encapsulate state). The main
e#ect of declaring a predicate persistent is that the dynamic changes made to such predicates persist
from one execution to the next one. After proposing a syntax for declaring persistent predicates,
a simple, file-based implementation of the concept is presented and some examples shown. It is
then argued that the concept developed provides the most natural way to interface with databases.
Such an interface to a relational database is then developed as simply one more implementation
alternative to the simple, file-based approach. The abstraction of the concept of persistence from
its implementation allows developing applications which can store data alternatively on files or
databases with only a few simple changes to a declaration stating the location and modality used
for persistent storage.
