Abstract

The ATLANT language is designed for the construction and operation of databases supporting various models. The language provides two levels of data definition: local data for a particular program and persistent data maintained for sets of programs. Persistent data are stored in one or several databases. Both local and persistent data are manipulated by the same set of statements. The data model is regarded as a set of data types and therefore the language provides a rich set of built-in specific and generic data types and tools for constructing user-defined types (both specific and generic).
