In this paper, a new structural model is proposed to ease the checking of the integrity constraints in an object-oriented database system. The structure accepts declarative global specification of constraints including user-defined constraint, and an efficient representation that permits localized constraints checking. A new method called "detection" is added to the structure to check the status of violation of the relations in an object-oriented database. The new approach is demonstrated using ALICE rule. The notion of the constraints is used to define the connectivity between objects required for the valid expression of constraint and rule conditions. The event in an event-condition-action (ECA) rule that defines the active behavior of an application specifies an operation to be monitored, such as modifying a data value. The semantic analysis process applies a concept known as object-centered conditions during the compilation of ALICE rules to detect semantically incorrect rules at compile time.
