  1. using Visio in the OGO 1.2 project (2004-2005) by Reinier Post

  2. 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. 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. 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. 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. 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. Visio support for OGO 1.2:logical models • Visio offers several solutions for logical (relational) database models • File->New->Database->ER Source Modelseparate database model • File->New->Database->Database Model Diagramto integrate several ER Source models • only Visio 2000 Enterprise !!! can generateMS Access databases

  8. Visio support for OGO 1.2:logical models • Visio offers several solutions for logical (relational) database models • File->New->Database->ER Source Modelseparate database model • File->New->Database->Database Model Diagramto integrate several ER Source models • only Visio 2000 Enterprise !!! can generateMS Access databases

  9. Visio support for OGO 1.2:logical models • features and caveats: • a complete relational database can be definedyou 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
