Semantic Constructs for a Persistent Programming Language
One objective of persistent languages is to permit the structure and semantics of data to be expressed precisely and simply. As a result programs are easier to write and the integrity of the data is less likely to be compromised. This paper presents a persistent programming language which includes a constraint definition and checking system. The language uses a semantic data model to define the structure and operations on data. The paper begins with a description of the features of semantic data models and constraint enforcement systems. The constraint definition aspects of the language Perci are then explained, along with an outline of the implementation of the constraint handling system. Perci is compared with existing persistent languages and the advantages of the new language are indicated.
