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	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?	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
