Not null (NN) attribute not showing on IDEF1X

Toad Data Modeler
1

Hello,

I just made an Reverse Eng from my database (SQL Server 2008), now I’m reviewing the diagram and I notice that when change the Notation to the IDEF1X Toad doesn’t show the NULL / NOT NULL flags.

I changed the options like (table -> object format -> entity -> display null mark) but it doesn’t works.

Any glue?

Thanks, Ésio

Hello Ésio,

IDEF1X notation in TDM is based on IDEF1X specification which does not explicitly define the Not Null flag, that’s why it’s not shown when using the notation.

If you’d like to see it, please add your request into the Idea Pond and depending on the request popularity, we may additionally implement it.

Regards,

Lukas
