Start a database transaction.
If you want to avoid round trips to the server or avoid the posibility of blocking other clients
because of your pending changes, you can use databaseManager.setAutoSave(false/true) and databaseManager.rollbackEditedRecords().

startTransaction, commit/rollbackTransacton() does support rollbacking of record deletes which autoSave = false doesnt support.
