Data access refers to both enterprise information system (EIS) data, and any local device data storage.
EIS data access requirements are fulfilled by mobile business object (MBO) definitions. This data access method is typically used in all applications.
You can also use local data access and store, which does not originate in the EIS and does not get propagated to any EIS, but is defined and captured as a local (or client-only) MBO. Local MBO objects provide object-based access and storage of application data in a device’s local database. Local MBOs typically are not used to store business critical data because code to migrate the data must be written into the device application source code whenever the device application is upgraded or a new version is introduced.
