Informally describe the conditions to be met for a relation to be in Second Normal Form.
In terms of functional dependency, describe why the following CUSTOMER_PURCHASE relation is not in second normal form. This table describes every instance of an individual Customer purchasing a Product.
How would this relation suffer from Update Anomalies?
CUSTOMER_PURCHASE
(CUSTOMER_ID, PRODUCT_ID, PURCHASE_DATE, PURCHASE_AMT, PRODUCT_DESCRIPTION, CUSTOMER_NAME) Note the relation’s primary key is underlined

Draw an ER diagram for the story below. Use the ERD tool only. Draw Relations in Oracle notation. Please read the story carefully. Use the mentioned Entities ONLY. The company sells various Products to Customers. The Sales Agent books an Order. A new order is created for each Product. While booking an Order, Agent records Order Date, Product, Customer, Product Quantity, and Sales Agent. Product has Description and UnitPrice. Each Agent reports to a Manager.

You should assume the sample data is representative. In what normal form is the relation? You must justify your answer by explaining why the relation is in the normal form you are claiming. Using the relation above, give an example of a deletion anomaly that may occur. Convert the relation into a set of relations in at least Third Normal Form, clearly indicating the primary and foreign keysarrow_forwardFor developing our queries, we will be using the following relational schema: Student(SID, name, username, major) Course(cname, description, department, weight) Offering(OID, cname, year, term, duration) Enrolled(SID, OID, grade) A course relation is the generic description of a course which is offered by a department. The offering relation is the specific instance of a course being taught in a given term, and is the entity which will be associated with the student enrollment. Students are enrolled in these offerings and achieve a mark. Express each of following queries in Relational Algebra: | Write a relational algebra query which will list the cname and description of all the courses which are being offering in the Fall 2018 term. 2 Write a relational algebra query which will list the name of all the students who have earned 60% in both 'COSC2P12' and 'COSC2P13'.arrow_forwardPLz help with the following: Translate your ER diagram into a relational schema in the form of SQL DDLs.

- In SQL, foreign key constraints can reference only the primary key attributes ofthe referenced relation or other attributes declared to be a superkey using theunique constraint. As a result, total participation constraints on a many-to-manyrelationship set (or on the “one” side of a one-to-many relationship set) cannotbe enforced on the relations created from the relationship set, using primarykey, foreign key, and not null constraints on the relations.
