Computer Science It is needed to design a database system for a pharmacy. The pharmacy contains many different items. Items may be products or medicines. Medicines are classified into different types either bills, injection, capsule or drugs or any combination of them. An item must be supplied by only one supplier. A supplier may supply many type of items. A customer may order many items. The pharmacy has a unique name, address and more than one telephone. The doctor can prescribe one or many medication, injections can not be bought without a doctor prescription. You are requested to draw the EERD diagram for the described system You are required to write down any assumptions made from your side You should add the attributes and cardinality for all the entities You are required to model the EERD into relational model
Course: Database Systems: Design and Application Web Shop scenario: A supplier (Supp-#) processes many purchase orders (PO-#) and sells a number of products (Prod-#). A product is sold by only one supplier. Each of the purchase orders that a supplier may process includes several products. The relationship between order and product is defined as "Line Item". A customer (Cust-#) may place one or more purchase orders. A purchase order may be placed by only one customer. Assignment requirements: Answer the following questions using above scenario: Identify the entities and attributes that required to draw the ER diagram. Integrate the entities with appropriate relationship and design the unified ER model.

Question IV: ER Modeling A social recreation club has a system to keep track of club members, committees and activities. Each club has a registration number and a title. Several members form committee. Members are male and females. Each committee has a name, a unique number and a date, which the committee has formed. The system stores the members’ unique identification number, name, address, gender, birth date and club joining date. The club forms committees for different activities. A committee controls and organizes a number of activities, each of which has a unique name, a unique number and description of the event. An event has event ID and description of the event. An activity may consist of several events. Committee publishes many online advertisements about the activities. Advertisement details are ID and a title. Draw the ER diagram to represent the above scenario

Many employees assemble an inventory item from many parts. A supplier supplies many parts. A part may be supplied by many suppliers.
Software development C#The application developed in Part 1 is already useful in terms of functionality, but it has a severe usability flaw: the data is not persisted, forcing the user to capture all the data from scratch if the application is executed again.For this part, you will continue working on the application you developed in Part 1. Remember to implement any feedback provided by your lecturer on Part 1 before working on Part 2. Marks will be awarded for this (see the rubric for details).All the requirements from Part 1 must still be met by the program, with the following changes and additions:1. The software shall persist the data in a SQL database.2. The user shall be able to register with a username and password.3. The software shall store only the hash of the password in the database.4. The user shall be able to log into the software with their username and password.5. The user shall only be able to see their own data and never that of other users.Non‐functional…

Data type 1.) Database Design : Take a crack at designing a simple database for 'A Small Dentist Office'. To keep it simple, please exclude any financial or billing information. So build a simple database that keeps track of patient information and appointments. Keep this very simple, maybe 4 tables. Part I: First determine the entities. The entities will be the tables. For example in an employee database the entities might be: an Employee, a Dept. These would then become the tables...the Employee table and the Dept table. Once you have come up with your 4 tables, move on to Part II. Part II: Design each table. Tables must include: a. Appropriate column names b. Data type for each column c. Whether a column can be 'null' or not d. Indicate any Primary Keys' and Foreign Keys'. e. Indicate any relationships with other tables PS → DO NOT USE MSAccess to do this Assign. I would use Excel for this Assign, or you could possibly use MS Word.

Create an Employee class and use the provided UML diagram to code the instance fields, constructors and methods. 3.1.1 Both constructors must increment the static numberOfEmp field by one. Both constructors must call the setEmpCode() method to compile a code for the employee. Both constructors must call the setCommission() method. 3.1.2 setEmpCode() method: The empCode must be constructed in the following way: First character is the type of contract Next three characters a random 3 digits Add a backslash and the number of objects value to the code NOTE: You have to use the Random class in your code (See Ch 9).
