Abstract: The present disclosure provides a bracewear for spinal correction and a system for posture training. The system for posture training involves both active and passive corrective forces by using the bracewear and a biofeedback system to address the spinal correction, which can eliminate the adversity of conventional hard braces and reduce the psychological and physiological barriers to treatment.

Abstract: Provided are techniques for savepoint processing. One of a savepoint statement, a rollback to savepoint statement, and a release savepoint statement is received. It is determined whether to propagate the received one of the savepoint statement, the rollback to savepoint statement, and the release savepoint statement to a data source based on an asymmetrical model in which a nested level of savepoints on a federated server side is capable of being greater than a nested level of savepoints on a data source side and wherein a two-tiered data structure is used to preserve savepoint information in the asymmetrical model. In response to determining that propagation is to occur, the one of the savepoint statement, the rollback to savepoint statement, and the release savepoint statement is propagated to the data source.

Abstract: Disclosed is a data processing system-implemented method, a data processing system and an article for manufacture for directing a data processing system to roll back to a savepoint located in a unit of work having a boundary generated by a boundary generator. The data processing system-implemented method includes examining a savepoint status indicator associated with the savepoint, and rolling back past the boundary to the savepoint depending on whether the examined savepoint status indicator indicates rolling back past the boundary towards the savepoint is permitted.

Abstract: A method for releasing a nested savepoint on a remote node of a database management system. The to-be-released savepoint is one of a series of savepoints represented by control blocks arranged in a linked list in the creation order of the savepoints they represent. Releasing of the to-be-released savepoint begins with receiving of a request to release the to-be-released savepoint. A control block is selected such that it represents the to-be-released savepoint or the next more recently created savepoint after the to-be-released savepoint. The selected control block is merged with all other control blocks that represent savepoints that are more recently created than the savepoint represented by the selected control block. The resulting merged control block represents all of the savepoints from the most recently created to the savepoint previously represented by the selected control block.
