Easily migrate your Oracle, Sybase, Interbase, MS SQL Server, IBM DB2, or Informix database to a MySQL database or reengineer your MySQL database. It's very useful to use domains. When you define an entity, you can use a global attribute definition, called a domain, to define an attribute locally. Before defining an attribute that references a domain, you must first create the domain. The domain acts as a template for defining attributes.
Domains are useful when many entities in a diagram contain identical attribute definitions.
A domain with domainitems will result in a definition of an enum-datatype. Attach this domain to the attribute to get a declaration of an enum-datatype on the resulting column in your generated MySQL scripts. You can change the datatype-mapping from within the program. You can export your diagram to a bitmap or gif-image. This image file can be included in your document.
