Mart building result with Martj

[Dada Damilola]

Hi Everyone, this is my first time trying out Biomart, and right now I have an issue with "Building Mart" from my relational database, according to section 3.1.2.1 of http://www.biomart.org/other/user-docs.pdf , the last few lines stated that after adding my table, I will see the interactions between the tables, but  I did not see it in my own case, and when I designed the database schema using workbench, there are lines of relationship between the table (
