KB10456 - Client-server and web-server development options using TatukGIS tools.

1. Using the DK-VCL edition. The DK-VCL may be used to develop a client-server application (in which DK code runs on each user station and on a server) or a true web server application (in which DK code runs only on the server). The DK-VCL developer can use the VCL source code to customize the bitmap serving procedure to optimize the performance for a web server environment. One option for the creation of either client-server or web server applications is to use the DK-VCL product with the IntraWeb development environment, which TatukGIS supports via the DK-VCL Component for IntraWeb. The DK-VCL IntraWeb Component is provided as part of the DK-VCL license package.
    
2. Using the DK-ActiveX or DK.NET editions. The DK-ActiveX or DK.NET edition can be used to develop client-server applications. These DK editions can theoretically also be used to develop a web bitmap image server solution, although this is not a main focus of these products. The DK-ActiveX and DK.NET do not contain an ASP.NET control for web development and these products are not optimized for bitmap image serving (which can result in performance/speed deficiency issues when the product is used for this purpose).
   
   The DK licensing (for all editions) requires the payment of a DK Server Deployment Royalty for each server computer to which a DK based server application is deployed (installed). For more about the server deployment royalty, refer to Developer Kernel License
   
3. Using the TatukGIS Internet Server (IS) product. This product is a ready-to-go GIS web bitmap image server based on Microsoft ASP.NET technology, and supporting the same object API and comprehensive functionality as the DK product. It contains both an ASP.NET control for web development and a Flash client control for smooth on-line map dragging and zooming and the editing of map geometry and attributes. (TatukGIS plans to add support for HTML5 in IS version 10.) Therefore, the development of a web server solution using the IS would typically require much less effort than the development of a web server solution using the DK product. The IS product is licensed per deployment server/computer.
    
4. The customizable TatukGIS Editor can be used as a thick client-side application in client-server configurations featuring the DK based software (or the TatukGIS Internet Server) running on the server side.
