Use GUI to make the application2. Do not use any builder to drag and drop componentIn java create an application to manage your data base information the database is already created in mysql tables, the tables are fill, So the user can use your database application user friendly Retrieve all data: Given a table name, retrieve all data from the table and present it to the user. Average: Given a table name and a column name, return the average of the column. Here the assumption is that the column type will be numeric (e.g., cost column). Insert: Given a table name, your program should show the column names of that table and ask the users to input new data to the table. In case of errors, your program should directly show the MySQL errors to the users. Assumption 1: Users will enter data according to the database constraints. Assumption 2: Users will input one record at a time. Delete: Given a table name, your program should show the column names of that table and ask the users to input data that they want to delete. Assumption 1: Users will enter data according to the…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. Use Visual Paradigm to answer the above question with following four UML diagrams: UML Diagram to be used: USE CASE (For Documentation), Class Diagram…
- ER- DIAGRAM/ DATABASE The European Parliament wants to create a database to help the various countries store information about its inhabitants. Your mission is to create an ER chart that captures the following information: In each country there are provinces, which contain cities. There can be no two provinces of the same name in a country. In the same way, there can be no two cities of the same name in a province. People live in cities. A person can be a man, a woman or a child, and have a first name, last name, ID, and birthday.Men and women work in a city. Children go to school in a city. Children are everyone persons under 18 years of age.A man can be married to a woman. For each marriage, they store the day for the marriage and information about who is the child of the married couple. You should assume that the parents of a child married at the time of her birth.JAVA Script Create a form that has a last name, a first name, an email address, a drop-down listing of 10 cities in Massachusetts. The list is to be sorted (hint: think array), an email address, and a zip code field. Each field is to be process through a validation function. You may use one function for each but if you are creative you should be able to use just one function. The drop-down listing will not require validation because they will be choosing from a list that you are providing. This input from must be styled and show an effect to the user as to which field that are currently providing input.Programming language to use: Java / Python Assignment: You have a dictionary of symptoms. Some are top level symptoms (Abdominal pain, Chest Pain) and others are children connected to these parents by relationships. Example: 'Abdominal pain, right upper quadrant' is a child of 'Abdominal pain' via relation 'location', 'Abdominal pain, mild' is a child of 'Abdominal Pain' via relation 'severity'. Dictionary: Abdominal pain Abdominal pain, right upper quadrant Abdominal pain, right lower quadrant Abdominal pain, left upper quadrant Abdominal pain, right upper quadrant Abdominal pain, mild Abdominal pain, moderate Abdominal pain, severe Chest pain Chest pain, left side Chest pain, right side Chest pain, mild Chest pain, moderate Chest pain, severe Tasks: Create the symptoms tree and print it.

[True / False ] In Swift, any variables can be simply used without having to declare them first. [True / False ] In Swift, functions can receive a function as an argument. [True/False] In Swift, functions can return another function as a complete argument.

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.
- calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100Project in Java programming language : Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.Open your text editor and create a new document named model.php model.php will contain functions that will connect to a database potentially return PDO statementobjects to the controller for processing. updateMessagesfunction updateMessages($id)This method will take a single parameter of id which is the saved id from the last or latest message displayed. It will conditionally select from the table “messages”, id, name, message, and time. The condition is that the field id is greater than the parameter for id. The return is the PDOStatement object with the row data from the query.
