You are creating a database for storing information for a Netflix like service. 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). Construct an E-R diagram (based on a Chen's model) to represent the above requirements. Make sure you include all appropriate entities, relationships, attributes, and cardinalities.

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.
in C# Visual Studios Windows Form App (.Net Framework) Population Database In the Chap12 folder of the Student Sample Programs, you will find a database file named PopulationDB.mdf. The database has a table named City. The City table has the following columns: (see image) The City column stores the name of a city and the Population column stores the population of that city. The database has 20 rows already entered. Create an application that connects to the PopulationDB.mdf database and allows the user to perform the following: Use data-bound controls to add new rows to the database, change existing rows, and delete rows. Sort the list of cities by population, in ascending order. Sort the list of cities by population, in descending order. Sort the list of cities by name. Get the total population of all the cities. Get the average population of all the cities. Get the highest population. Get the lowest population.

Your team is building an API for a music store application. The application lets users look up songs and albums by many different data fields (artist, publishing year, genre, etc). As you are working on the prototype for the application, you have a library of about 1000 songs and 100 albums. You have decided to store the data about songs and albums in DynamoDB and your approach for searching has been to run a Scan on the table for the different fields that the user has entered. For instance, if the user wants to find information about rock songs written in 1970, you might scan a Songs table with filter conditions on the genre and publishing year. Does this approach seem like it will work as you scale up to (hopefully) millions of songs and albums? Why or why not? What kind of steps could you do to improve scalability? Edit Tble

In 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…
For this project you will have to build a web application for managing a support ticketing system (STS). The application must be implemented with PHP. You can use a relational database like MySQL. - Non-logged-in users should see a “Register” menu link on all pages, which leads them to the registration page - The registration process requires the user’s email, password, name and team - The email should be a valid email address and not exist in the system (two registered users cannot have the same email) - Passwords should be at least 6 characters long and should contain both letters and numbers - The team should be one of the following values: Development, Support, Sales - Proper validation should be performed by the system, and detailed error messages displayed - Non-logged-in users should see a “Login” menu link on all pages, leading to the login page - login page asks for user email and password.
In this project you will implement a student database using JavaFX. A GUI should be used as the program's interface. This program must consist of two classes. (1) The first class should define the GUI and handle the database interactions: a. Combo box should allow the user to select one of the four database actions (Insert, Delete, Find, and Update). b. The database should be implemented as a HashMap, with the ID field as the key and a student record consisting of a name and major as the value. c. The operation should be performed when the user clicks the Process Request button. d. If the user attempts to insert a key that is already in the database an error message should be displayed using a JOptionPane message dialog box. e. If the user attempts to delete, find or update a record that is not in the database, a message should also be displayed. f. After each successful operation is completed a JOptionPane window should be…

Create a MySQL Database called “CSC306Class”. Create three (3) tables in the database called “studentInf”, “IntructorInf”, and “LikedAndDisliked”. Each table should consist of five columns that are relatable to the table name. Insert at least five row of data in each table. The data can be any information as long as it is related to the table name. If you were able to download and setup an php server on computer. Try to create the database, tables, and rows. Then upload a screenshot and code. Please help me with the practice problem I have created.
Computer Science The goal of this assignment is to create an app that can capture, tag, save, and retrieve photos on your smartphone.Capture: When clicked, it takes a picture and shows a thumbnail image. Tag: A user can type multiple tags (separated by a “;”). Save: When clicked, it saves the photo in a database along with the tags. Load: A user can specify one or more tags. Your app will find and show the first photo that had any of those tags. When there are multiple photos matching the criteria, the App should have an UI element to show them one by one, e.g., when the user slides a slider.
