An overview of siderues: A graphical database schema editor for Galileo

Abstract

Sidereus is a workstation based graphical tool to edit a Galileo database schema using a diagrammatic notation. Several tools to manipulate a graphic representation of a database schema exist as commercial products or research prototypes, but the novel aspects of this proposal lie in the fact that the graphical editor is used to model a database using a semantic data model, to deal with complex objects with the values of attributes definable using the rich type system of Galileo, a database language that supports the abstraction mechanisms of semantic data models. Moreover, schemes designed with Sidereus are translated automatically in Galileo code, executable on the same workstation.
