Implement a new independent entity phone in the Sakila database. 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'.

As a stage of designing the Semuarasa restaurant database, some entity information and documents are known as follows. • Food Menu: consists of menu code, name of food menu, food category, area of origin, price, picture menu (one menu can have many pictures), number of portions available per day.• Customer: customer code, full name, place of birth, type of phone, address, email, cellphone number, WA number.• Employee: employee code, employee name, cellphone number, and method.• Restaurant Branch: Branch code, branch name, address, city, telephone number, WA number, email.• An example of a purchase receipt form as follows. 1. From the information above, do the normalization steps from 1NF, 2NF to 3NF. 2. Draw ERD from the table of results for the 3NF. ERD is completed with all the attributes of each entity, PK, FK, multiplicity (participation and cardinality). 3. Do an enhanced entity-relationship with ERD, complete with participation and disjoint constraints.

Your job as a database designer is to design a database with a schema that captures all the information that galleries need to maintain. Galleries keep information about artists, their names (which are unique), birthplaces, age, and style of art. For each piece of artwork, the artist, the year it was made, its unique title, its type of art (e.g., painting, photograph, sculpture), and its price must be stored. Pieces of artwork also classified into groups of various kinds, for example, portraits, still lives, works by Picasso, or works of the 19th century; a given piece may belong to more than one group. Each group is identified by a name (like those just given) that describes the group and property. Finally, galleries keep information about customers. For each customer, galleries keep that person’s unique ID, name, address, total amount of dollars spent in the gallery, and the artists and groups of art that the customer tends to like. Draw the ER diagram for the database.
