I am creating a Forum. I have several products. Each may have several subcategories.<br />
For example:<br />
Product1<br />
&nbsp; &nbsp;General Questions<br />
&nbsp; &nbsp;Technical Issues<br />
Product2<br />
<br />
In this example Product1 has 2 subcategories but Product2 has none. In <u>General Questions</u>, <u>Technical Issues </u> and <u>Product2</u> the user can create a thread.<br />
<br />
What tables should I create for that? So that it handles both products with subcategories and without?
