To upgrade your models, you opened each model in the new version. For more information about borrowing licenses, see the Installation Guide.Įarlier, when you upgraded to a new version of CA ERwin DM, only the schema was upgraded.

#Erwin data modeler v7.1 license

By default, the maximum period for which a license is borrowed is 168 hours. The Mobile licensing feature enables you to borrow a license from a License Server on any mobile device that supports CA ERwin DM.

A custom profile generated from the UDP dictionary is applied and user property information is stored in the tag values of the applied custom stereotypes.Here is what is new for CA ERwin Data Modeler:.

A custom UML profile is created for the user's property definitions.

Paths between elements can be re-routed.

Due to geometric constraints and element size changes, the diagram layout will be slightly different.

The Validation rule is stored as constraint body text.

This instance specification is (or can be) then referenced from attributes, default value fields.ĭomains are not yet supported in Cameo Data Modeler.

A standalone UML instance specification is created to hold value definition.

Verb phrase information is not imported.

Referential integrity information is stored in a special stereotype / tag.

Discriminating columns are imported / supported.

Complete / incomplete and overlapping / exclusive settings are imported / supported.

Generalizations are joined into generalization trees.

ERwin relationships participating in the generalization tree are mapped to UML generalizations.

Key information is not imported since the current ER diagrams do not support FK modeling. Referential integrity information is stored in a special stereotype / tag. Simple relationships are mapped to UML associations.Ĭardinality and null / not null settings are mapped to UML multiplicities (,, , ).

Instead, attributes belonging to a key are marked by applying a stereotype to them (PK, AK, or IE) as necessary.

There is no separate standalone model element for a key in the Cameo Data Modeler ER diagrams.

Other types (those not found in the model) are created on the fly.

Attribute type information is imported - the standard primitive types are mapped to the UML primitive types.

Domain information is not imported because domains are not supported.

Attribute constraints and default value information is imported.

The Null / Not Null setting is imported as UML multiplicities /.

Definitions are imported as MagicDraw documentation (special UML comments).

For each element, its name, definition, and notes are imported.

Import mapping reviews and notes are in the following table.

If you want to update an imported and edited ER model (for example, you made changes to the ERwin model and want to import those changes into MagicDraw again), you can use the merge functionality (click Tools > Project Merge) to import the ERwin model into a new ER model and merge it with the model you have imported earlier. If you want to include the ER model as part of a larger project in MagicDraw, you can use either module linking functionality (click File > Use Module) to attach the ER model to your main project model or project import functionality (click File > Import From > Another MagicDraw Project) to transfer the contents of this ER model to your main project model. A new MagicDraw project will be created and a logical model will be imported from the ERwin model file into that project.Īfter a successful import, you can proceed to edit or manage the model using MagicDraw features. Click File > Import From > CA ERwin Data Modeler v7.x.

Data models in ERwin must be saved in the *.xml format (choose the XML Standard File option in the Save As dialog). It is recommended that you use the newest v7.3 since it has been heavily tested. The Cameo Data Modeler Plugin does not yet support importing physical layer data.Ĭameo Data Modeler supports model files produced in ERwin version 7.x. The import functionality only imports logical layer data from ERwin into ER diagrams / data models in MagicDraw. The logical layer corresponds to ER diagrams implemented by the Cameo Data Modeler Plugin. The physical layer semantically corresponds to the SQL modeling / diagramming / generation functionality in MagicDraw. ERwin is one of the leaders in the data modeling tools market.ĭata models produced in ERwin have a two-layer structure, consisting of tightly synchronized logical and physical layers. The Cameo Data Modeler Plugin for MagicDraw provides import functionality for data models created using the CA ERwin® Data Modeler (henceforth will be referred as ERwin).
