An attribute corresponds to a column in a table. A synchronization parameter maps to an attribute that acts as a filter or variable that lets you limit the data that is returned to the device to rows in the table based on a supplied value.
For example, if a table has a "country" column, a user can supply "USA" as the value in his or her synchronization request. Unwired Server filters and returns only the rows that meets the specified criteria.
- The user initiates a synchronization request that includes an attribute value (synchronization parameter).
- Unwired Server filters the data in the CDB. For example, if the attribute is "country" and the user supplied the value "USA," only rows that contain "USA" are returned to the device.
If the user later supplies the value "Europe", rows for both "USA" and "Europe" are returned to the device, and so on.
- Unwired Server synchronizes the device with the results.
