Smart Clients are an evolutionary step over rich client and web client applications, capturing the benefits of both and then adding to them. Smart Clients are defined by the following attributes:
High fidelity user experience that:
Exploits the latest in graphics and UI technology
Is personalized/individualized for each user based on context
Intelligent connection:
On/offline intelligence - taking advantage of local data caching and processing
Distributed - central corporate data stores and pre/post processing on a server connected through web services
Interoperable - Smart Clients can easily access data from many heterogeneous sources
Information centric:
Data access is loosely coupled
Data is easy to retrieve, cache, and post
Data access is flexible and granular in setting what, when, and how data is accessed and affected Designed for operations:
Secure
Centrally deployable
Local CPU processing leveraged intelligently
Versionable Depending on the complexity of the application needed, Smart Client application developers will vary in how they apply these many different technologies. Longhorn has a strong focus on building new applications from scratch by building a local client application with Avalon. Developers also want to extend (customize) their existing applications to fulfill new application scenario needs. Additionally, both new and customized applications will need to integrate into existing systems.
Smart Client developers won't make an all-or-nothing choice of web or client, they will leverage the strengths of the technologies they need and create the right solution for the business opportunity at hand. A Smart Client solution empowers the developer to rapidly build the right solutions that provide timely and fresh data access in an occasionally-connected complex world. Simply stated, Smart Clients will surpass rich clients - they're rich clients ++.

The user experience for interacting with today’s moderately complex web applications is less than satisfying. The web’s pagebased model and lack of clientside intelligence makes even relatively simple transactions (online shopping, for example) too confusing for many users. Moreover, complex user interactions, like those in traditional client/server and desktop applications, are nearly impossible to complete. This technology has led to a generation of web applications that are difficult to use, costly to support, and, in many cases, largely ineffective. In response to delivering improved user experiences, a new category of Internet applications is emerging: Rich Internet Applications. These applications combine the responsiveness and interactivity of desktop applications with the broad reach and ease of distribution of web applications. Rich Internet Applications drive increased return on investment (ROI) by simplifying and improving the user interaction of web applications. They make it possible to deliver applications that provide a richer, more interactive, and responsive user experience. Macromedia is widely recognized as a leader in the emerging market for Rich Internet Applications. The Macromedia Flash client is available now on 98% of browsers, so almost everyone can use Rich Internet Applications based on Flash. Macromedia Flex is a new server product from Macromedia that makes the full power of Rich Internet Applications accessible to enterprise application developers. Flex has a standardsbased architecture that complements current enterprise developer tools, methodologies, and design patterns. This white paper provides an overview of Macromedia Flex, and Macromedia’s Integrated Development Environment for Flex applications, Macromedia Flex Builder.
For many years the primary focus of solution developers has been in deploying Web-based applications. However, there are certain situations when the limitations of a Web-based application can prevent you from really providing your customers with the best possible experience. In those times you really need a Smart Client application. Today's model for building Smart Client applications provides us with both local processing and access capabilities of a traditional application, as well as the ease of deployment and update that is the hallmark of a Web-based application.
