A local video shop has hired you to create a database for them to store all the client information. Each clients name, surname, address and contact number must be saved for them to register. They also need to store the videos according to category. The video title, running length and released date needs to be stored. They need to know how many videos they have and whether the video is in the shop. Each client buys units that enable them to hire videos. You can buy lots of different amounts of units (50, 100, 200, 500, 1000) Do the following for the above scenario: 1. Draw an initial ER Diagram 2. Normalize the ER Diagram from ONF to 3NF (3 marks per NF) 3. Draw a 3rd NF ER Diagram

You are asked to create a database for a busing company. You need to keep track of the differ- ent buses, each having a plate number, make year, and number of seats. You also need to keep track of drivers that work in the company. The information kept on each driver should include the license number, age, and name. Finally, you need to keep information on which drivers are allowed to drive different buses. Drivers cannot drive any bus, but rather each driver is assigned with specific buses in the fleet he/she is allowed to drive. Accordingly, a driver may be allowed drive many different buses, and a bus can be driven by many different drivers. 2. Convert the ER diagram that is found in the next page to a logical relational data model. Submit in your file the relational model you arrived at (i.e. the list of tables, their columns, indicating their primary and foreign keys). Note: You are NOT asked to create an Access Database, but rather only provide the list of tables you would have in…
You have been tasked with creating a database solution for a local library. This database will be used to keep information about the books owned by the library and which books are checked out by customers. You are given the following information: The database will need to store information about books, authors, and customers. Books can have multiple authors. Authors can write multiple books.

You have been hired at Selianord Group (Pty)Ltd as a Junior database developer where you are going to build a desktop application called LusuFlix. This application will be used at a video rental store. We need different levels of permissions for different users in the database. The store manager should be able to add/update/delete the list of movies. They will be in charge of setting the stock for each movie as well as the daily rental rate. Cashiers should have a read-only view of the list of movies. They should be able to manage the list of customers and the movies they rent. At check out, a customer brings one or more movies. The cashier looks up a customer by their phone number. If the customer is a first-time customer, the cashier asks for their full name, email, and phone number, and then registers them in the system. The cashier then scans the movies the customer has brought to check out and records them in the system. Each movie has a 10-digit barcode printed on the cover.…

When you use a transaction, the database tables/views/other resources used in the transaction are locked until the transaction is either committed or rolled back in order to ensure all modifications are either ALL made, or none of them made. Usually databases also have options on the level of locking used such as no one can read or make changes to those resources when locked, or users can’t make changes to the resources but they can read data in the tables/views/read access to resources. Pick a potential problem with database locks on tables/views/resources and one popular way database administrators and / or database users use to address that problem?

Your task is to develop a database, in order to keep information on all sales at a motorcycle dealership. The database will include information on motorcycles, salespeople, sales, and customers. We assume for simplicity that the dealership sells only new motorcycles and that all motorcycles are produced by the same manufacturer. Each kind of motorcycle is called a model, and it has a unique model number. For each model, you want to store also its name, engine size in cubic centimeters (cc) which is an integer number, and the date when this particular model was introduced. For each salesperson, you want to store their employee ID number, first name, middle initial, last name, and the date when the employee was hired. For each customer, you want to store a customer ID number, first name, middle initial, last name, address information (city, state, and zipcode), phone number (given in standard US format), and e‐mail address. Assume that you do not have a zip code table available. Each…
