Sample text

Transition values are temporary data describing the state changes performed by a transaction, whose content is affected by the rule's level of granularity: "• When changes are monitored at the instance level, transition values are changes affecting a single tuple or object, typically accessed by means of the OLD and NEW correlation variables. " When changes are monitored at the statement level, transition values are collective changes, collected into temporary structures such as the tables INSERTED and DELETED.

5 Chimera's trigger processing algorithm While the conflict set is not empty do: 1. Select one trigger T from the conflict set among those rules at highest priority; T's state becomes untriggered. 2. Evaluate the condition of T. 3. If the condition of T is true, then execute the action of T. Trigger selection at step 1 of the above algorithm produces one of the triggers at highest priority from all the triggers that are considered by the trigger processing algorithm; before and after clauses introduce a partial order between both immediate and deferred triggers.

4 Examples of Trigger Executions All examples refer to the following database schema and initial state: define object class Employee attributes Name: string, Salary: integer, Mgr: Employee end; define object class SpecialEmp attributes Name: string end; define object class Department attributes Name: string, Employees: set-of(Employee) end; Class Employee: { (ol,'john',3500,o2) (o2,'tom',4500,null) (o3,'bob',4300,o2) } Class SpecialEmp: Class Department: {} { (o4,'toys',{o1,o2,o3}) } Let us consider first a trigger targeted on the Employee class, which monitors creation and salary modification.
