I have a database project, historic building materials... I've designed 4 Tables like this (there are more fields which I didn't listed here): table products - primary key(productid) - product description ... table category - primary key(categoryid) - category description table subcategory - primary key (Subcatid) - subcatdescription table subtype - primary key (suptypeid) - subtype description now I like to join those tables. For example I got the product of a single door (there are other doors which are double doors. This product belongs to subtype single doors, which than belongs to the subcategory doors and category historic building material out of wood. My aim is to have a hyperlink which shows me the categorys if click on it it shows me the subcategorys and than the subtype and than the products which belong to all this. So if I now create another table called for example table Ids - productID - categoryID - subcatID - subtypeID will I be able to join those together and get all I want to achive building it like this? Or do I have to many tables to join together? Also the Id's make up my product code say for example category b.m.o of wood makes number 10 (20, 30, 40 for others) subcategoryid will be 1 for doors (2,3,4 there after) subtype also 1 (2,3,4) and than the products will be 1, 2 , 3 etc. My logic doesn't let me think of any other way. So if anyone has a good suggestion on how to go about this please let me know. Thank you so much if you find the time to help me out here.
