MC Which statement is CORRECT? The OID of an object remains the same during the entire lifetime of the object. correct An OID is the same as a primary key in a relational database setting. incorrect Each literal is defined by an OID according to the ODMG standard. incorrect Two objects with the same values always have the same OID. incorrect MC In Java, what is method overloading? Putting so much code in a method that its functionality becomes hard to understand. incorrect Offering the user of your class all possible methods that he/she would like to perform on the variables the class offers. incorrect Making sure that every method uses all variables of the class. incorrect Using two methods with the same name, but a different number (and/or different type) of arguments. correct MC Which statement is NOT CORRECT? A class can be instantiated into several objects. incorrect Objects are instances of classes. The people "Bart Baesens", "Wilfried Lemahieu" and "Seppe vanden Broucke" could be instances of the class "Person". incorrect Objects store both a piece of information and ways to manipulate this information. incorrect Objects are blueprints of classes. "Human", "Employee", "Sale" are examples of objects. correct MC Which statement is CORRECT? An OID is the same as a primary key in a relational database setting. incorrect The OID of an object remains the same during the entire lifetime of the object. correct Two objects with the same values always have the same OID. incorrect Each literal is defined by an OID according to the ODMG standard. incorrect MC Objects should be made persistent when... you need them over multiple program executions. correct you only need them during 1 program execution, and then never again. incorrect MC Which statement is NOT CORRECT? A class can be instantiated into several objects. incorrect The OQL language provides no explicit support for INSERT, UPDATE, and DELETE operations. incorrect An object's state is determined by its attributes and relationships. incorrect Each literal is defined by an OID according to the ODMG standard. correct MC Which statement is CORRECT? An OID is the same thing as a primary key. incorrect All relationships in ODMG's ODL should be defined in a bidirectional way. correct OODBMSs typically deliver worse performance for complex queries than RDBMSs. incorrect A class must have exactly one constructor. incorrect MC Which statement is NOT CORRECT? Objects are blueprints of classes. "Human", "Employee", "Sale" are examples of objects. correct Objects store both a piece of information and ways to manipulate this information. incorrect Objects are instances of classes. The people "Bart Baesens", "Wilfried Lemahieu" and "Seppe vanden Broucke" could be instances of the class "Person". incorrect A class can be instantiated into several objects. incorrect MC Which statement is NOT CORRECT? OQL can be used for both navigational (procedural) as well as associative (declarative) access. incorrect In order to model a N:M relationship type in ODL, an extra class must be introduced, much like in the relational model. correct Static binding binds a method to its implementation at compile time. incorrect An object's state is determined by its attributes and relationships. incorrect MC Which statement is NOT CORRECT? OQL can be used for both navigational (procedural) as well as associative (declarative) access. incorrect OQL is a declarative, non-procedural query language. incorrect The OQL language provides no explicit support for INSERT, UPDATE, and DELETE operations. incorrect Join queries are not supported in OQL. correct
