Basic data synchronization requirements are common for relatively simple data access and collection applications that are usually new and replace paper-based systems. The basic data synchronization server acts as a communications server managing the simultaneous connection of many users and passing information between the device s data store and a server database through a conduit. A variety of communications modes are supported. Thus users may connect through desktop cradles wireless data communications dial-up or direct network access. Basic synchronization capabilities include Basic enterprise infrastructure platform features see below Integration with the standard device synchronization mechanism such as HotSync for Palm hand-helds Multiple communications modes Field-level change posting Full device refresh Refresh from an intermediate repository Support for standard IP Detailed logging and alerts Extensive administrative control and configurations Part of a total mobile and wireless data infrastructure solution1 Basic synchronization servers typically have a documented API. The IT organization writes the conduit previously mentioned. This conduit is custom code written to the API of the synchronization server to define the data mappings data sharing and synchronization logic and supporting functionality. For straightforward applications the conduit coding effort is easily accomplished. With more complex requirements it is more efficient to utilize an advanced data synchronization server than to try to write additional functionality and management tools into your conduit. Typical requirements that favor the robust functionality and rich management tools of an advanced data synchronization .
