Abstract
Conceptual schema design is a central problem in designing databases and information systems. GISD is a workstation-based interactive system for creating, maintaining and integrating conceptual schemas of the Binary-Relationship model, utilizing Information Analysis methodology and its graphic formalism for conceptual schema design. GISD functionality, architecture and interaction flow are descibed. Special emphasis is given to making the user interface consistent and convenient, utilizing workstation capabilities and software engineering techniques. These techniques are applicable to other database design interactive systems and make GISD the basis of a more generalized software tool.
