“…The two other steps of that method are applied to two classes of constraints each of them fulfilling certain conditions. See [15] Each of these intra-constraints is obtained according to an occurrence of an object variable in the quantifier structure of W 1 . The intra-constraint W pr is obtained from W 1 according to the object variable pr.…”

“…It is essential for any consistency management approach to provide the feature of integrity independence [7,15], that is the ability to change constraints specifications without changing the application programs and transactions and vice versa. To provide this feature for our approach we must separate constraint specifications from transactions and class methods.…”

SUMMARYThe paper presents concepts and ideas underlying an approach for consistency management in objectoriented (OO) databases. In this approach constraints are considered as first class citizens and stored in a meta-database called constraints catalog. When an object is created constraints of this object are retrieved from the constraints catalog and relationships between these constraints and the object are established. The structure of constraints has several features that enhance consistency management in OO database management systems which do not exist in conventional approaches in a satisfactory way. This includes: monitoring object consistency at different levels of update granularity, integrity independence, and efficiency of constraints maintenance; controlling inconsistent objects; enabling and disabling constraints, globally to all objects or locally to individual objects; and declaring constraints on individual objects. All these features are provided by means of basic notations of OO data models.
