A synchronization protocol is provided that can be used to resolve synchronization errors encountered while trying to synchronize versions of data objects between a client device and a remote computing system. The protocol includes a client device, in an offline processing mode, handling user interface ('UI') manipulation actions on one or more UI elements of one or more UI screens. The handling of the UI manipulation actions modifies or creates a local version of a data object stored on the client device. The UI manipulation actions are stored by the client device and sent to the remote computing system. The client device receives a synchronization error notification from the remote computing system. After receiving the notification, the client device displays, in one of the UI screens, the local version of the data object and one or more indications of a synchronization error.

Data synchronization error resolution based on UI manipulation actions

Systems and methods for minimizing database accesses in an object-oriented system may involve opening an object in a buffer, wherein the buffer is operative to store both an active version of the object comprising active content and an inactive version of the object comprising the inactive content modified by one or more inactive requests. An activation manager may be operative to determine whether the one or more inactive requests are consistent with an applicable object model. Because the buffer stores is operative to store both an active version and an inactive version of the object, it may implement commands to change the object between the inactive and active states without accessing the database. Upon receiving a flush command, the buffer may also be operative to make any version of the object stored in the buffer at that time&#x2014;whether active, inactive, or both&#x2014;persistent on the database.
