- Instructions: Create a complete ERD in Crow's Foot notation that can be implemented in the relational model using the descriptions below. The attributes required: Activity's ID, Activity's Title, Activity's description, Child's ID, Child's firstname and lastname, Child's Birthday, Parent's ID, Parent's number, Parent's address. The business rules are: An activity may or may not have a child signed up An activity may have many children signed up A child must have an activity A child may have many activities A child must have a parent A parent must have a child A child may have many parents A parent may have many children To submit: Write your answer in a clean sheet of paper and upload a picture of it to dropbox32. In a relational model, relations are termed as a. Tuples b. Attributes c. Rows d. TablesImplement 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'.

- Change ER DIAGRAM TO RELATIONAL SCHEMA. WRONG QUERRY DOWNVOTE GURANTEE THANK YOUWhat are three advantages of using a surrogate key rather than the main key to access a relation instead?Relational model: In the personal model, data are prearranged in tables, which contain of table. A data in a table is called fields. Fields in a db table are also referred as qualities of a db object. A group of related fields are called as a record, which I also called as db object or entity. A group of records are called a table. Keys in a relational db table refer to a key field. To identify each record in a table, there must be at least one data field that should be unique. That is, a corresponding data field of every record should be unique. Therefore, key field is used to identify the unique record from a collection of records.
