Using 4D Version 6.5 gives you the winning advantage and your applications all new possibilities, power, and speed. In addition to the 130 new commands, query, indexing and sequential operations are significantly faster. The integrated web server produces tighter HTML on-the-fly and supports HTML frames, multi- homing, DHTML and more. If you're discovering 4D for the first time, your timing could not have been better. Spend a few moments learning about how 4D 6.5 can exceed your expectations by equipping you with the most significant web application development technology available.

Start Small and Build Big

With 4th Dimension v6.5 you can start with simple database structures and use 4D's wizards to create automatic data entry and report forms. You can use the built-in querying and reporting tools to generate sophisticated reports with no coding. As your needs grow you can add custom methods to automate data entry, validation and reports. You can add menus and form objects and procedurally control them to create completely customized user interfaces.

Improved Performance and Productivity

4D version 6.5's database engine has been highly optimized to improve performance on queries, sorts, exports and indexing. No coding is required to take advantage of these significant performance gains.

Improved Form Wizards

With the 4D Form Wizards you can automatically create simple or advanced forms. You can then drag and drop objects onto any form from the Tools palette to create sophisticated interfaces. Form properties, events and methods are all managed from the form, using either contextual menus or the new Properties List palette. The enhanced picture editor allows you to import, edit and create picture libraries for use in forms and buttons. Even animated pictures can be created quickly and easily.

Improved Debugger

Multiple debugger windows can be open simultaneously to allow you to step forwards and backwards through your application code, inspecting the status of database objects as your code executes. Debugger windows and their states can be saved. Improved Web Serving 4D v6.5 incorporates data management on the web as a standard database task within the integrated 4D Client/Server architecture. 4D automatically converts its forms to HTML on the fly, allowing users to connect through their preferred web browser to create and edit data. You can also add Java script and Java applets to 4D forms to validate data entry. 4D's contextual mode allows you complete control over record navigation and selections while non-contextual mode allows 4D to behave like any web server. Plug-in areas, such as 4D Chart, are now automatically converted to HTML, images or image maps.

Cross-Platform Development & Deployment

You can develop and deploy on both Mac OS and Windows with full support for both interfaces. Users can log on as web clients from any operating system.
