Entity Relational (ER) Diagram:
The following figure illustrates the ER Diagram for given business rules using Crow’s Foot notation:
Explanation:
The above ERD contains several entities such as “PATIENT”, “APPOINTMENT”, “DOCTOR”, “PATIENT_PAYMENT”, “VISITING”, “BILL”, “VISIT_DETAIL”, “INSURANCE” and “INSURANCE_PAYMENT”. Each entity has its own attributes.
- A doctor keeps several patients; similarly, a patient may request many doctors. Hence the relationship between the entities “DOCTOR” and “PATIENT” is M: N...

How would I go about creating this computer database in MariaDB with sql?
Create a database name "dbXXXXXX" Select the database using the "use [database name]" command.
Now you are in the database.
Based on the above schema from Enrolment System database, create all the tables with the last 6 digits of "123456", then the table name for table Lecturer should be "123456_Lecturer". Refer to basic SQL lecture note to create table that has primary keys and Foreign Keys. Provide the datatype of each attributes.
Add a column called "Department" with datatype "VARCHAR(12)" to the table "Lecturer". Shows the metadata of the updated "Lecturer" table. (Use Describe command)
Drop the "Department" column from the table "Lecturer", and show the metadata of the updated "Lecturer" table.
Insert three (3) data to each of the table in the tables created.
Note: If you have foreign key issues, please disable foreign key constraints before inserting the data, see below

Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why?
