- Normalize the following given data to 1/2/3 NF. State the relations schema after everynormalization.Using Normalization technique decompose the above un normalized relation to reach the 3NF, clearly showing all the steps involved to reach each Normal Form (NF). CustNo, CustName, Addr, SuppNo, SuppName, SuppTel, (ordNo, orderDesc, QtyOrdrd)If a parallel data-store is used to store two relations r and s and we need to join r and s, it may be useful to maintain the join as a materialized view. What are the benefits and overheads in terms of overall throughput, use of space, and response time to user queries?

Attributes and relationships are shown in the following diagram: The diagram uses Sakila naming conventions. Follow the Sakila conventions for your table and column names: All lower case Underscore separator between root and suffix Foreign keys have the same name as referenced primary key Write CREATE TABLE and ALTER TABLE statements that: Implement the entity as a new phone table. Implement the has relationships as foreign keys in the Sakila customer, staff, and store tables. Remove the existing phone column from the Sakila address table. Step 2 requires adding a foreign key constraint to an existing table. Ex: ALTER TABLE customer ADD FOREIGN KEY (phone_id) REFERENCES phone(phone_id) ON DELETE SET NULL ON UPDATE CASCADE; Specify data types as follows: phone_id, phone_number, and country_code have data type INT. phone_type has date type VARCHAR(12) and contains strings like 'Home', 'Mobile', and 'Other'.
