All of the content on the RTI web pages, such as the article you are now reading, is maintained in a relational database (RDB) by the RTI Site Manager, a PHP3 and HTML based website content manager, and extracted by the RTI web server when a web page requests it.

The RTI Site Manager provides the webmaster with the ability to add, view, update, and remove content from the website via a user-friendly web-based interface. When the Site Manager is used to view a HTML content item, the browser renders the HTML in a WYSIWYG display. However, when updating the item, the raw HTML is displayed for ease of editing.

While the page you are currently viewing is static, the process of retrieving the page content dynamically from a RDB potentially allows dynamic content to be retrieved and displayed as it becomes available in the database. For example, data that changes daily, hourly, or even by the minute can be written to the database, and every time the referencing page is accessed or refreshed, the latest data written to the RDB will be displayed.

When a content file is initially deleted, it is left in the database and flagged as "deleted". It can be re-activated by using the "undelete" function, or permanently deleted by again using the "Delete" function. This two-level delete process helps prevent unrecoverable deletion errors.

The "Site Manager" brings to reality the vision of dynamically updating and viewing content from anywhere on the internet, whether you are an end user or an administrator.
