1 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e using Visio in the OGO 1.2 project ( )the OGO 1.2 project ( ) by Reinier PostReinier Post

2 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 2 / 9 what is Microsoft Visio? a very powerful diagram editor you can use predefined diagram techniques: “stencils”, “templates”, “solutions” you can define your own diagram techniques

3 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 3 / 9 Visio support for diagram techniques: shape properties Visio can be used to draw shapes (vector-based) shapes have many properties some properties control a shape’s appearance some properties control a shape’s behaviour some properties define extra right-click actions pages and documents have properties, too

4 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 4 / 9 Visio support for diagram techniques: stencils and templates Visio documents (*.vsd) contain shapes shapes can be collected in stencils stencils can be saved as documents (*.vss) Visio documents can be opened together with stencil documents a template (*.vst) is an example document

5 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 5 / 9 Visio support for diagram techniques: solutions Visio can be made to “understand” a diagram technique: arbitrary program code (macros / addins) can be associated with Visio documents, stencils and templates a Visio “solution” = stencil(s) + template(s) + (optionally) code File->New-> lists available Visio solutions

6 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 6 / 9 Visio support for OGO 1.2: conceptual models you can draw “Silberschatz” ER models with Visio I have a “solution” (stencil) to help with this (not yet available online, URL will be published) warning: work on paper until you have a reasonably detailed diagram, or you waste a lot of time redoing the layout in Visio warning: work on the layout in Visio until it prints nicely on A4, Visio’s automatic layout function doesn’t work

7 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 7 / 9 Visio support for OGO 1.2: logical models Visio offers several solutions for logical (relational) database models File->New->Database->ER Source Model separate database model File->New->Database->Database Model Diagram to integrate several ER Source models only Visio 2000 Enterprise !!! can generate MS Access databasesVisio 2000 Enterprise

9 / department of mathematics and computer sciencedepartment of mathematics and computer science / architecture of information systems architecture of information systems technische universiteit eindhoven TU/e p. 9 / 9 Visio support for OGO 1.2: logical models features and caveats: a complete relational database can be defined you must error check it to spot all problems Visio maintains an abstract database model the diagram displays a subset of the model strange error messages are usually caused by objects not being displayed in the diagram
