				<title>Using logical columns in entities</title>
				<description><![CDATA[ I am currently using VP to design an ER model for an application framework, that uses a proprietary metadata repository. To keep my model consistent, I want to use logical columns in my entities, which should not be generated using DDL. For example:<br> If I model an object <i>product</i>, which should have a multilingual title (stored in the repository of the framework) and other columns, stored in a traditional table (e.g.: article number, goods group etc.), the approach would be as follows:<br> <br> create table product (productID int not null, article_no bigint not null, goods_group varchar(255) null) primary key (productID)<br> <br> --> Column  <i> title </i> does not appear in the physical table.<br> <br> But in VP, I want to document the metadata column correctly, so the entity should consist of the following columns:<br> <b>productId int not null</b><br> title (only logical, no DDL generation)<br> article_no bigint not null<br> goods_group varchar(255) null<br> <br> Any ideas, how to perform this?]]></description>
