Create an application that allows users to comment on a static posting that you provide. In one version, the user’s name, contact information (e-mail address), and comment will be saved to a single text file. In the other version, the same information will be saved to a database table. Include functionality that allows anyone to view who has visited the site and left comments. While the comments will automatically be displayed by date (as this is how they are saved to the text file and database table), allow the viewer to sort comments in ascending and descending order (by name) to more easily find a comment. Do not allow users to comment more than once to the posting. In doing so, prevent duplicates from being saved to the text file and/or database table. You will want to plan how to save data to the text file and database table for easy retrieval. To get started, create an XHTML document that will serve as a main page where you can enter your information and comments. This page should also provide the ability to get to the other existing comments on the posting. Upon providing a comment, you should acknowledge the addition of the entry by showing what values were added. You should also allow a different user to add an entry
