Object Orientation is an approach to software construction that solves some of the major problems of software deevelopment.Traditionally softwrae engineering and database management hav eexisted as separate disciplines. data base techonology has concentrated on the static aspects of information storage,while software engineering has modelled the dynamic aspects of the software.
WIth the arrival of third generation of Database Managment Systems, namely Object Oriented Database Management System and Object Relational Database Management System, the two disciplines have been combined to allow the concurrent modelling of both data and the processes acting on the data.
Object Oriented Database Management System (OODBMS) provides all the facilities associated with the object oriented paradigm. It enables one to create classes, organize objects, structure an inheritance hierarchy and call methods of other classes.Along with that it also provides the facilities associated with the standard database system.
Advantages of Object Oriented Database Managment System:
- Enriched Modelling capabilities: the object oriented datamodel allows the real world to be modelled more closely. An object can store all the relationships it has with other objects,including many to many relationships, and objects can be formed into complex objects that the traditional data models cannot cope with easily.
- Extensibillity: OODBMS allows new datatypes to be built from existing types.The reusability of classes promotes faster development and easier maintenanace of the database and applications.
- More expressive Query Language: Navigational access from the object is the most common form of data acces in an OODBMS.
- Support for achema evolution: The tight coupling between data and applications in an OODBMS makes schema evolution more feasible.
Thus Object Oriented Database Management System (OODBMS) is a database system that implements all the concepts of Object Oriented paradigm including Polymorphism and operator overloaing.

Programming Question 4: Operator Overloading [20 marks] The class SpecialArray represents an array of integers. The class contains two data members: array (of type int"), which represents the array of integers, and size (of type int) that represents the size of the array. The class SpecialArray also overloads the following operators: operator: Compares two arrays. An array "A" is smallerhan an array "B" if the size of array "A" is smaller than the size of "B", or if...

C++ questions T/F The compiler will report an error if the + operator is overloaded in a way so that it performs subtraction. T/F When a unary operator is overloaded using a member function, it accepts one explicit argument and returns a class object. T/F The size of an operator cannot be overloaded. T/F Operator overloading also allows creation of new operators. T/F To convert a class object to basic data type, a conversion operator needs to be included publicly...

Consider the following protocol for concurrency control. The database system assigns each transaction a unique and strictly increasingly id at the start of the transaction. For each dataitem, the database system also keeps the id of the last transaction that has modified the data item, called the transaction-id of the data item. Before a transaction T wants to read or write on a data item A, the database system checks whether the transaction-id of A is greater than the id...
