![]() ![]() Type the path and file name for the model that you want to import, or click the Browse button to locate the model file, and then click Open. On the Database tab of the ribbon, in the Model group, select Import, and then select the file type you want to import from. If you have not already associated the Visio database driver with a particular ODBC data source, click Setup. ![]() Select the Microsoft Office Visio database driver for your database management system (DBMS). On the Database tab of the ribbon, in the Model group, select Reverse Engineer. On the right side, select either Metric Units or US Units, and then select Create. Under Template Categories, select Software and Database, and then select Database Model Diagram. For more information about how to name a range of cells, see Define and use names in formulas. These ranges are treated like tables in the wizard. If you want to use more than one worksheet, just name the group of column cells in each worksheet. If you're going to reverse-engineer an Excel workbook, first open the workbook and name the group (or range) of cells that contains the column headings. If you have a database that you want to model so that you can understand it better or use it as a starting place for a new model, you can use the Reverse Engineer Wizard to extract the schema, or structure, of the database and build a new model. In the Tables and Views window, select the tables that you want to model, and then drag them onto the drawing page. The imported tables are displayed in the Tables and Views window. Visio imports the file and displays its progress in the Output window. Type the path and file name for the model that you want to import, or select the Browse button to locate the model file, and then select Open. On the Database tab, in the Model group, select Import, and then select the model type. The Reverse Engineer Wizard opens automatically. This ability is limited to only VisioModeler 2.0 or later dictionary model (.imd) files and PLATINUM ERwin 2.6, 3.0, and 3.52. If you have an existing VisioModeler or PLATINUM ERwin model, you may be able to import it to create a Visio database model diagram. Select the database driver for your database management system (DBMS). ![]() On the first screen of the Reverse Engineer Wizard, do the following: If the wizard doesn't open: On the Database tab of the toolbar ribbon, in the Model group, select Reverse Engineer. The Reverse Engineer Wizard should open automatically. In the search results, double-click Database Model Diagram. ![]() In the Search box, enter database model and press Enter. This step ensures that the wizard maps the native data types correctly and that all the code that is extracted by the wizard is correctly displayed in the Code window. For more information about how to name a range of cells, see Define and use names in formulas.įor best results, set your default driver to the target database that you want to reverse engineer before you run the Reverse Engineer Wizard. These ranges are treated like tables in the Reverse Engineer Wizard. To avoid ambiguity in type names, the default namespaces list in the query dialog should include the UML metamodel URI ( for the above UML.ecore file).If you have a database that you want to model so that you can understand it better or use it as a starting place for a new model, use the Reverse Engineer Wizard to extract the schema, or structure, of the database and build a new model. The rest of this article will run on this toy XMI-based UML file, which was exported from this Modelio 3.2.1 project: If you are using any predefined UML data types, you may also want to add a PredefinedUMLLibraries location inside "Indexed Locations": that will integrate those predefined objects into the Hawk graph, allowing you to reference them on queries. In order to index XMI-based UML models, you only need to enable the UMLMetaModelResourceFactory and UMLModelResourceFactory plugins when you create a new Hawk instance, and ensure your files have the. All the queries are written in the Epsilon Object Language. These are some sample queries that can be done on any set of indexed XMI-based UML models, assuming that Class::name has been added as an indexed attribute and Class::ownedOperationCount has been defined as a derived attribute (as showed in the core concepts page). ![]()
