Abstract:
Integrating handheld data entry into a data management system can be accomplished elegantly with Java, SAS and XML. The availability of Java on both server and client platforms (including handheld devices) provides end-to-end connectivity in support of a S
AS service-oriented architecture. XML is rapidly becoming the lingua franca of structured data representation on the web but the challenge is to use it appropriately.
This paper describes the use of handheld computers for data entry using disconnected mod
e for remote deployment. The form-based data entry provides quality assurance on the handheld through validation mechanisms and other constraints. In order to simplify deployment, the project is using a web services model to deliver form definitions and to
retrieve data via XML over wireless.
