I am using DB2 Database for my huge data in my company but to make a physical database design I need a tool to design.where I can make foreign,primary key relationships and also we have spatial data.
So the tool should have spatial data type also.

I am using IBM Infosphere data architect but it does not have spatial data type. Please suggest how to enable spatial data type or suggest me for new tool.

Thanks & Regards
