SteelBlue is an open-source Web application server environment in which Web-database applications can be developed completely in an extended HTML language. Similar to ColdFusion and Story Server, session and user-associated data as well as SQL commands can be directly embedded into the HTML page. Therefore, no CGI programming experience is required to develop applications with SteelBlue, only knowledge of SQL and HTML.

What distinguishes SteelBlue ?

- True extension of HTML. SteelBlue commands maintain the HTML format. This allows new SteelBlue elements to seamlessly integrate with existing HTML commands and also allows prototyping of pages with existing HTML editors.

- Automatic security enforcement. Security is enforced before a single line of a script is executed, therefore reducing any potential holes from mistakes by a Web developer.

- User groups. Special abilities can be granted to or removed from users through association to groups. This permits administrators and normal users to share the same web application.

- Automatic restoration of form data.

- Automatic server and client-side type checking.

- HTML generation, data checking and resulting database interaction may be combined in a single SteelBlue script. This leads to more modular code that is easy to maintain.
