A department store is developing a database system for supporting product searching in its online shop. The sample product form below identifies some of the relevant data.

This is a longer note that states whether a material is natural or not, what it is made from, how it is supposed to be washed and ironed, etc. When the system finds a product sought, it should be able to match automatically the select product with matching product one or more (e.g., a white blouse can be matched with both a white and a blue jacket). These matches are pre-programmed. a) From the above sincere identify the relation with their attributes b) Write down the different types of fundamental relational algebra operations. With the above relation give show the composition of relational algebra operation. A department store is developing a database system for supporting product searching in its online shop.
