ERD for Sales Order
Step 1.
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. A Manger has a Nameand Commission Percent.
NOTE: Total Amount is a calculation, doesn't belong to Order
Step 2.
Add Attributes to Sales Order ERD based on Rules of Normalization.
Given the following relation vendor order (vendor no, order no, vendor name, qty supplied , price/unit) the second normal form relations are
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

- NORMALIZATION EXERCISE Based on the given relation schema below, perform normalization up to 3NF. Write your answer in below space ORDER (Order_ID,Date,Cust_ID,Cust_Name,State,City,ItemNO,ItemDescription,ItemPrice,Quantity) 1NF 2NF 3NFarrow_forwardPLZ help with the following: Consider the following relations: Suppliers (Snumber, sname, address) Parts (Pnumber, pname, color) Catalog (Snumber, Pnumber, Qty) Find the suppliers names who supply the part number 7with quantity greater than 50. Select one: a. πSname(σPnumber=7 (Parts)) b. πSname(σPnumber=7 and Qty>50 (Catalog)) c. None of the above d. πsname(σPnumber=7 and Qty>50 (Catalog) (Parts))arrow_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_forward
- Normalize the following given data to 1/2/3 NF. State the relations schema after everynormalization.arrow_forwardIn 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.

- Based on the above Relations/Tables, write description of violations of each of the 3-constrains in the table given below: Just answer without explanation please.arrow_forwardUse the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.arrow_forwardIn 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. Explain how to enforce total participation constraints using complexcheck constraints or assertions (see Section 4.4.8).

After determining the functional dependencies, convert this table to an equivalent collection of tables that are in third normal form. Do not create a diagram of the tables. Instead use the symbolism like that found in the textbook when showing functional dependencies.
