Use the Entity Relationship stencil to model databases that are based on the If you have not already associated the Visio database driver with a particular. I have to do an ER diagram for a bunch of database tables however I just realized I have Visio standard on the PC I'm using and thus the Database. Concpets (FMC) diagrams like Block diagrams, Petri nets and Entity-Relation diagrams (ERD). The FMC Stencils for Visio 5 and OpenOffice are very basic.

That is, type in "C: The template "UML 2. If you'd like the UML 2. Stencil and Template for Visio This stencil for Visio contains all the same shapes as the stencil for Visioas Visio has almost the same functionality as Visio ; there were only usability improvements.

Start Visio, click "Tools" and "Options".

In the "Advanced" tab, click "File Paths Stencil and Template for Visio This stencil for Visio contains all the same shapes as the stencil for Visio Visio has disabled some functionality compared to previous versions, therefore "Edit Text" in right-click menus is not available. This functionality is considered a security risk in Visio and I am working on a user-friendly solution to put this functionality back. Unzip the stencils and template to the same folder.

The stencil does not contain angled connector available in Visio 5. I removed the angled connector because the more advanced routable connector provides the same functionality and is more reliable in Visio than in Visio 5. Compared to Visio 5.

Typically, Visio keeps stencils and templates in the folder C: The stencil contains all the same shapes as the stencil for Visio 4. The stencil also contains an angled connector that you can use as a reliable alternative to the routable connector. Compared to the stencil for Visiothe size of the pentagon in the Frame and Interaction Occurrence symbols is determined by size of text, and cannot be set independently on the text size.

If you make any improvements yourself, please be so kind as to let me know. To change the data type for a column, click the column's Data Type field, and then select a data type from the list or type it into the list. For example, you can type decimal 8,2 or char To prevent null values, select the Req'd check box. To specify that the column is a primary key, select the PK check box.

To see more column properties in addition to those that appear when you click the Columns category, select the column and then click Edit. Relationships Relationships use primary and foreign keys to allow databases to match a row in one table with a row in a related table. You can show those relationships in your diagram. In addition, you can set their cardinality for example, one-to-many and use either Crow's feet, Relational, or IDEF1X notation to show the cardinality.

You can't show many-to-many relationships with any of these notations in the Database Model Diagram template. Create a relationship between tables: Make sure that both tables are visible in the diagram.

If you reverse engineered the model from an existing database, you may need to drag one or both from the Tables and Views window onto the drawing page. Double-click the table that you want for the primary key side of the relationship. In the grid, click the column that you want to use to uniquely identify each row in the table, and select the PK check box to set it as the primary key. From the Object Relational or Entity Relationship stencil, drag a Relationship shape and drop it onto a blank space on the page.

Connect the higher end to the table with the parent table. Connect the other end to the child table. If the second table doesn't already contain a column with the same name as the primary key, the modeler adds it to the second table as a foreign key. If relationship lines disappear, on the Database tab, in the Manage group, click Display Options. On the Relationships tab, under Show, select the Relationships check box.

Set the relationship's cardinality: In the Database Properties window, under Categories, click Miscellaneous.

Under Cardinality, choose the cardinality that best fits the relationship. For one-to-many relationships, the best choice is either Zero or more or One or more. For one-to-one relationships, the best choice is either Zero or one or Exactly one. To make other refinements to your diagram such as creating indexes, check clauses, and triggers you can do the following: Create indexes Indexes improve the performance, or speed, of your database when you run a query. Open the database model diagram.

Double-click the table to which you want to add an index, and in the Database Properties window, in the Categories list, click Indexes.

In the Create Index dialog box, type a name for the index, and then click OK. In the Index Type list, select an option to create a unique or non-unique index. In the Indexed Columns list, select the Asc check box to create an index that has an ascending sort order, or clear the check box to create an index that has a descending sort order.

The database model diagram is updated. Create views You can think of a view as a saved query. Views are particularly handy if you need to repeatedly access the same information from multiple tables, or if you want to expose the data to users without letting them change the actual tables. Set extended properties for tables and views Depending on your database management system DBMSyou may be able to set extended properties for tables or views to determine where they are stored.

Double-click the table or view whose extended properties you want to set, and in the Database Properties window, in the Categories list, click Extended. Create check clauses Use check clauses to ensure that the data that is entered into a column is within a particular range of values. For example, you can create a check clause that requires the data in a column called "Age" to be over Double-click the table to open the Database Properties window.

Under Categories, click Columns and then click the column that you want to add a check clause to. On the Check tab of the Column Properties dialog box, enter the constraints that you want. The check clause is added to the Code window under Local code. Create stored procedures and user-defined functions Use stored procedures and user-defined functions to create packets of code that you can reuse to perform the same actions repeatedly. The major difference between the two is that a user-defined function returns a value, whereas the stored procedure executes code without returning a value.

Click Global Code and then click New. On the Properties tab of the Code Editor, click the kind of code that you want to create, and type a name for the code.

On the Body tab, type the code and then click OK. Create triggers Triggers cause SQL code that you specify in the trigger to run when a particular event occurs in the database. Under Categories, click Triggers, and then click Add. On the Properties tab, type a name for the trigger. The trigger is added to the Code window under Local code.

Can't find the database model features? Most likely, your edition of Microsoft Office Visio doesn't include the features that you are looking for. The name of the edition is in the top line of text in the dialog box.

Microsoft Office Visio Professional supports the reverse engineering features for the Database Model Diagram template that is, using an existing database to create a model in Visiobut it does not support forward engineering that is, using a Visio database model to generate SQL code. You can find the full suite of database modeling features, including both reverse engineering and forward engineering, in Visio for Enterprise Architects.

On the Database menu, point to Options, and then click Document. If you are reverse engineering a Microsoft Office Excel workbook, before you start the wizard you need to open the workbook and name the group or range of cells that contains the column headings. For more information about how to name a range of cells, see the topic in your Microsoft Office Excel help titled Define named cell references or ranges.

On the Database menu, click Reverse Engineer.
