Filtering and Synchronizing Data

Use filters and paramters to synchronize selected subsets of data.

Specifying a synchronization parameter during mobile business object (MBO) development allows you to control the amount and type of data that is returned to the device during synchronization. Without synchronization parameters, large amounts of unnecessary data may be downloaded to devices, making viewing difficult and needlessly expending resources, such as device battery life, memory, and network bandwidth.

• Load Parameter Data Flow
  Load parameters allow you to limit data stored in the Unwired Server cache and returned to the device based on the values the device user supplies via the parameter over time. They can be paired with synchronization parameters to also control synchronization.
• Synchronization Parameter Data Flow
  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.
• Result Set Filter Data Flow
  A ResultSetFilter is a custom Java class deployed to Unwired Server that manipulates rows and columns of data before synchronization.
