Shorthand representation of the relational
- The shorthand representation is used to represent the database table in an easier and an understandable way by using primary keys.
- The step wise process for representing a shorthand representation of a database structure is as follows:
- First, the Table Name is written down.
- Using paranthesis, list down all the columns or fields in the table within the paranthesis.
- From the shorthand representation, data such as primary keys can be identified.
- In this kind of representation, bold or underline data is used to represent a Primary key.

INDICATE THE CHANGES(USING SHORTHAND REPRESENTATION) YOU WOULD NEED TO MAKE TO THE ORIGINAL KIMTAY PET SUPPLIES DATABASE DESIGN TO SUPPORT THE FOLLOWING REQUIREMENTS. A CUSTOMER IS NOT NESSESARILY REPRESENTED BY A SINGLE SALES REP, BUT THEY CAN BE REPRESENTED BY SEVERAL SALES REPS. WHEN A CUSTOMER PLACES AN ORDER THE SALES REP WHO GETS THE COMMISSION ON THE INVOICE MUST BE IN THE COLLECTION OF SALES REPS WHO REPRESENT THE CUSTOMER
Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements.
There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.

Given the database specification below, your job is to turn the specification into an ER diagram. Your notation must be consistent with the notation used in our lecture notes. You can use all constructs and notations discussed in our lecture notes and nothing else (i.e.. oven notations used in the textbooks but not in our lectures cannot be used). Your ER diagram should capture all the information and constraints in the specification but, at the same time, be minimal. It means that redundant entities, relationships, attributes and constraints should be avoided. You may use any drawing tool of your choice (for example, Dia, diagrams.net, Lucidchart, etc.) to draw your ER diagram. Hand drawings will not be accepted.

So before creating the database, your task is to draw the ER diagram based on the following data collected and analyzed: A hospital will have a name, unique id, multiple helpline numbers (one for doctor's appointment, one for ambulance, one for bill information and one for other services' info) and locations. A hospital may have more than one location as it may have different branches and each of the locations will have a building no., street address, road no. and city name. A patient will have a name, unique ID, may have more than one phone number, age, height, weight and symptoms. A patient takes an appointment in a hospital and the appointment date is recorded. A patient may have an attendant. An attendant will have his/her name, contact numbers and relationship with the patient as a record in the database. Due to the covid situation, the hospital authorities will only allow 1 attendant with 1 patient.arrow_forward

Normalization is the process of applying a series of rules to ensure that your database achieves optimal structure. Normal forms are a progression of these rules. Each successive normal form achieves a better database design than the previous form did. Based on your understanding for the various normal form respond to the following problems and provide the optimal answer/solution.
