Product Database design of e-commerce website

2. The usual design will put the product attributes into the product table, such as color, size, size and so on. But I took the attributes out of two separate tables, a table with the name of the property, and a list of property values.

3. Originally considered to brand the table, but then think about the brand can be placed in the attribute table, the product as a property into the P_property table, and then the value of the brand corresponding to the attribute value table.

4. I do not know if there is any shortage of such design, and then this point, hoping to have the power of the great God to come to the direction of the business.
