An efficient dual caching strategy for web service-enabled PDAs
Xin Liu, Ralph Deters · 2007
PDAs have evolved over the years from resource constrained devices that supported only the most basic tasks to powerful handheld computing devices. However, the most significant step in the evolution of PDAs was the introduction of wireless connectivity which enabled them to host applications that require internet connectivity like email, web browsers and maybe most importantly smart/rich clients. Being able to host smart clients allows the users of PDAs to seamlessly access the IT resources (e.g. legacy apps) of their organizations. One increasingly popular way of enabling access to IT resources is by using Web Services (WS) [14]. This trend has been aided by the rapid availability of Web Service (WS) packages/tools, most notably the efforts of the Apache group [1] and IDE vendors (e.g., Microsoft's Visual Studio [2], IBM's Eclipse [3]). Using IDE tools and other software packages it is fairly easy for programmers to expose application interfaces and/or consume existing interfaces leading to a gradual replacement of the current web server centric approaches (e.g. ASP, JSP, Servlets, CGI scripts) with WS centric approach.
