PROBLEM IDENTIFICATION: I work at a screening theater. The theater maintains no record of tickets sold, due to which the seats at the theater are usually over-booked. Due to this we usually have to refund money to those who aren’t able to be seated even though they have purchased a ticket. This causes great confusion when it is time to make the accounts at the end of a financial year. This has also led to a decrease in the theater’s reputation and fewer sales. This system will help the managers of theater keep track of ticket sales and ensure no over-booking of seats by computerizing the inefficient manual system. Also being a new employee at the theater I am not well informed about the movies that are being screened. Therefore I need a log that will provide me upon search with the details of the film so that I may deal with any customers’ queries knowledgably.
INPUT DATA: 1. 2. 3. 4. 5. 6. 7. 8.
Movie ID code: Holds the ID code of the movie, used for easy reference. Movie’s name: Holds the movie’s name Genre: Describes what genre the movie belongs to Director’s name: Holds the name of the director of the movie Rating: Shows what rating has been prescribed to the movie by the censor boards Cast Details: Name of the cast of the movie Movie screening date: Date the movie is being screened on Tickets already sold: number of tickets that have been sold already.
OUTPUT DATA: 1. 2. 3. 4. 5.
Shows a list of all the movies contained in the log Shows all movies showing on a particular date Displays all movies falling in a certain genre Display al movies that have been awarded a certain rating Display all movies according to the seat availability (e.g. fully booked, less than half of the seats booked, barely booked, etc.)

PROGRAM DESIGN: Design a program in Visual Basic which is user friendly and menu based. Here the user will be allowed to add, edit, erase, find and save details about movies, along with being able to perform other basic functions like clear or cancel any ongoing work and quit a menu, or open up another menu. Entry is gained via a log-in screen. The salesperson will be able to issue tickets via this system. The logs will contain details that a person visiting the theater might require to know. Also this new system will ensure that no tickets are sold once the theater’s seating capacity is met, by keeping a track of all transactions, ensuring no over booking. The logs will be saved in a notepad file “project1.txt.” Also print outs of reports can be made according to search by rating, genre, date the movie showing on, seat availability, etc.
