Mobile Business Object (MBO) is the base of Sybase Unwired Platform (SUP). Mobile Business Object (MBO) contains the business process logic and data into a reusable unit. MBO is easily accessible from mobile clients. MBO development can be Top-Down & Bottom-Up. Top-Down approach creates the MBO based upon how the client wants to use it & at the end it is binded to data source. Bottom-Up approach starts with data source with automatic binding & then creating MBO.
