Yes you can use the same column name in a database and in a schema. The only thing is that you have to precede the field with the table name when you're joining 2 tables containing columns with the same name.

Let's open a can of worm.

There are 2 stands on this :
1. Something should have the same name everywhere in the DB. For example, product_id should be product_id in the product table and in the monthly sales table.

2. Each column should be prefix by the table abbreviation so in the product table it is prd_product_id and in the monthly sales table something like mthlysl_product_id.

Personnaly, I prefer the first one.
