1. You are asked to design a database for Banks. A bank will have one unique Code, Name andAddress. Banks will have multiple branches and each of those branches will be numbered (1,2..), first branch will be Number 1 for example and these will have an address of their own besides thebranch number. The Bank Branches will offer the option of creating accounts to customers, they willalso have the option of creating joint accounts. Customers will be able to open different accounts ineach of the bank branches. Account information will include the unique Account Number, TotalBalance and Account Type. The Bank Branches will also give Loans to Customers. Loans will haveunique Loan Number, Loan Amount and Loan Type. A customer can take multiple loans from acertain bank branch and banks can issue a number of different types of loans just like accounts. Thecustomer’s National_ID, Name, Phone and Address will be taken and stored. Using theseRequirements please construct an Entity-Relationship…

4. Movie Store System
This is a system for selling and buying DVDs and videos of movies. There will be three types of users.
First the regular customers, they can access the database of DVDs and videos with different types of search.
Second there is a group of users that can post DVDs or/and videos to be sold. These users have access to
add movies to the database, so that regular customers can search for these movies. When the customer has
finished searching for a DVD and/or a video he/she can communicate a message to the seller in order
to buy the product from him. The third class of user is the administrator; this user will be in charge of
administrating the database and users. The administrator will be in charge of giving and revoking
selling privileges to regular customers so that they are able to add videos and DVDs in the database.

The user need to register on the app by entering name, age, address, reading interest (e.g. fiction/nonfiction). The user will be provided with a user name/email ID, which will be used to maintain the record of each unique user. The app should ask a user to log in with a user name and password. Once the user is logged in, the app should display three options “Add a book, update a Book and Borrow a Book. If a user chooses add a book option, new activity should open asking for book details (title, author, publisher and publication year). If a user chooses update a book option, new activity should open showing a particular book details and should give the option to update the book’s information including status.

When a product code is entered and then a quantity is entered, on the enter key pressed, the product code is sent to the getProduct(String ID) of a ProductDAO object and that function connects to the database and retrieves the data, placing it into a Product object and return this as Product object so that it can be placed into the Jtable of the PosGUI screen.

The database also stores users, each user has an id, username, password. Users may watch zero or more movies, zero or more TV show episodes. For each movie or episode, the database stores a watch time value for each user, indicating how many minutes the user watched that movie or show. Finally, the database stores which movie appears similar to which other movie for a given user (to be able to make recommendations).

To make a reservation you must be registered as a user of the system. In order to register you choose a unique username and enter your name, address, and telephone number (the address is optional). When you use the system later, you just have to enter your username. In the system, a number of theaters show movies. Each theater has a name and a number of (unnumbered) seats. A movie is described by its name only. (In a real system you would, of course, store more information, such as actor biographies, poster images, video clips, etc.) A movie may be shown several times, but then during different days. This means that each movie is shown at most once on any day.
