We have a web application that deals with some common sales entities (Contacts, Appointments, Addresses, Notes etc..). We need to keep our app, outlook, and potentially any devices that they might have synchronized.
Are there any frameworks that we can use that help us integrate with PDAs? Any thoughts or reccomendations are appreciated. Thanks.

Answer 1

I think that the SyncML article on Wikipedia would be a good start.
Funambol has clients for multiple platforms and the core project is free and open source.
Plaxo.com has customized a funambol Windows Mobile clients for their customers.

I would look at Microsoft Sync Framework. Whitch has many "providers" both some included, some open source, some 3rd part. A provider is a like a standardized "connection" to a datasource, like outlook mail, outlook contacts, file system, database or whatever you can imagine. Or as Microsoft says:
Microsoft Sync Framework is a
comprehensive synchronization platform
that enables collaboration and offline
access for applications, services and
devices. It features technologies and
tools that enable roaming, sharing,
and taking data offline. Using
Microsoft Sync Framework, developers
can build sync ecosystems that
integrate any application, with any
data from any store using any protocol
over any network.
A key aspect of the Microsoft Sync
Framework is the ability to create
custom synchronization providers. A
provider is a software component that
represents a replica for
synchronization. A replica is a
particular repository of information
to be synchronized, such as a file
system on a handheld device. When
representing a data source, a provider
enumerates changes from its replica.
When representing a destination, a
provider applies changes to its
replica. If the data at the source and
destination differ in type or schema,
each provider performs any necessary
mapping or transformation.

Contact Synchronization Sample - Outlook Sync
This sample shows how custom providers can be created to synchronize content between disparate data sources. In this sample we will synchronize Contacts between Microsoft Outlook, Vista Contacts and VCard files. A key aspect of this demo is the data mapping capabilities which enables disparate data sources and data types to be mapped appropriately through the Sync Framework:

I've done this with the Microsoft .NET Compact Framework and had excellent results. SQLCE can provide local storage on the PDA. Syncing can be performed either with custom code over web services or using something like SQL Server Replication.
Another strategy would be to design a second web portal with a UI that is specifically targeting mobile devices with small screens. Smart phone-based users could access the mobile portal with any web browser. This might be the most cost effecive solution.
