Question

Develop An Application That Allows The Input Updating And Deletion O Develop an application that allows the input, updating, and deletion of customers, homes, salespersons, and sales from your Reston Real Estate (RRE) Oracle database in the VDA that you have been using since Project #2. Develop a test scenario that adds 3 (three) homes, 3 (three) customers, 1 (one) salesperson (i.e., agent), and 3 (three) sales. Each new customer must be involved in a separate sale for one of the new homes. The new salesperson is involved in all three sales. Take screen snapshots of each step operation mentioned. After the initial data above are input, change one customer's last name, another customer's address, the salesperson's phone number, and the sale amount of one of the homes. Take screen snapshots to prove that this worked. Provide an option to allow the user to display the total number of homes sold in your database (the new ones and any previous ones), the total sales amount (new and existing), and the average sales amount per home (new and existing). Take screen snapshots to prove that this worked. Finally, delete all 3 (three) of the new customers, homes, sales, and the new salesperson. Take screen snapshots to prove that this worked.

Introduction The development of a comprehensive application that manages core real estate data—namely customers, homes, salespersons, and sales—is vital for streamlining operations within a real estate agency. Specifically, this application targets the Reston Real Estate (RRE) database, built on Oracle databases within a Virtual Desktop Environment (VDA). The goal is to implement functionalities for data input, updating, deletion, and reporting, leveraging best practices in database management and application development. Methodology The implementation process involves designing a user interface that connects to the Oracle RRE database and allows CRUD (Create, Read, Update, Delete) operations for the key entities. For this purpose, a custom application—possibly built using tools such as Java, Python, or a web framework—would be employed. Each step involves carefully scripting database transactions, validating entries, and capturing screenshots that document each procedure. The initial test scenario involves populating the database with three homes, three customers, one salesperson, and three sales records. Each customer is associated with a distinct sale involving a newly added home, with the same salesperson involved in all transactions. These entries demonstrate the application's capacity for inserting multiple records and establishing correct relational links via foreign keys, such as customer IDs, home IDs, salesperson IDs, and sale IDs. Next, updates are performed on the data: changing customer last names, addresses, salesperson phone number, and modifying the sale amount. These modifications demonstrate the application's update capabilities and ensure data integrity through validations and constraints. Furthermore, the application provides reporting functionalities that compute and display aggregate data, such as total homes sold, total sales amount, and average sales per home. These reports are essential for management decision-making and offer insights into
