16.2.2 Types of LANSA Applications
- The best choice for working with Unicode data, because they allow data from different languages to be displayed and edited in the same form or webpage, is a Windows Optimized LANSA application. This is because it is created to make full use of the features of high function graphical user interface (GUI) environments. Windows Optimized application components are fundamentally different from Universal applications because they must be event driven to support high function GUI controls such as grids, tree views, graphs, charts, drag and drop, multimedia, and so on.
The Universal Model, is NOT recommended when working with Unicode data. It does not support display of Nchar fields – these must be copied to Alpha fields and that means data loss if the data is not all in the current code page.
- The Visual LANSA Framework is an optional extension to LANSA which provides an application framework for designers and developers. A key benefit of the Framework is that from a single application model it supports deployment to Windows Rich Client, Web Browser, or Microsoft .NET.
