Phases of web development

The process of developing web application and websites which works using the internet is known as web development. Web developers need to use scripting languages at both the server and client end. A content management system is necessary to create a static website (one page) to a full-blown web application. Website development includes the coding of the application logic, designing the user interface, incorporation of database and managing the user queries, hosting the website on the server, and maintaining and updating the website.

Using Java, create a personal directory that contains a data structure for first name, last name, email address and phone number. The data structure should be able to contain the information for an unlimited number of people (depending on system resources).• The program interface should consist of a menu that provides the user with ways to (at least):▪ Add: Get data from user and add the data to the structure.▪ View: which will view the current data in the directory ▪ Edit/Update: Edit existing data ▪ Remove: Delete an entry▪ Search: which prompts the user for search criteria (program should be smart enough to know how to tell what kind of data is being searched for. Try to make this as versatile as possible). Display the data if found. If not found add the new information to the data structure (you must provide the right input for this).The program should store the data in a file so that the program can be run whenever the user wants, even after closing.• Your program should:▪ Contain…

Create a structure called applianceTvpe with the following members. Use the proper variable TYPES for the members: name; SUpplierlD: modelNo: cost; Create an array variable of type applianceType that can hold 50 components. Write the code segment to read from a file into the structure array. Declare an input file stream identifier for this purpose. Open the file and read until end of file. Keep a count of how many rows actually read. The data file contains the following data: RefrigeratorABC 80 4657 521.62 ToasterOven 100 3245 245.96 MicroWave 95 7878 345.67 Using a looping construct, output to the console (cout) the data read into the structure array. Make sure you do not go outside the bounds of the array or beyond the number of rows actually read. You do not need to write any #include statements, using statements and you do not have to write code to open the file. Assume the file is open. You do need to declare variables needed for the program segment.
In Python Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents…

Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…
