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…
- 1. Develop a data manipulation application with a user-friendly JavaFX GUI for student's database (as shown in the ER diagram below).

The database stores movies with id, title, filename and TV shows with id, title. TV Shows have episodes. Each episode has a corresponding TV show, a season id, an episode id, title, filename. Some episodes have a next episode (i.e. the episode that will automatically start showing once the user finishes watching the current episode!). 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).

- The screen shown is used to enter the sales of the products into the sales and salesdetails tables. It utilizes the four depicted files ProductDAO.java, Product.java, PosDAO.java and Pos.java. The schema for the database is also depicted. The java code utilizes a jconnector to retrieve data from the database. 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. Write the code for the getProduct(String ID) function located in the ProductDAO file. The code is equivalent to the prodid.Create a database class in python.
