The construction of Object-Oriented Database Management Systems started in the middle 80 ’s‚ at a prototype building level‚ and at the beginning of the 90 ’s the first commercial systems appeared. The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors‚ that is the relational database management systems. They were intended to be used by applications that have to handle big and complex data such as Computer Aided Engineering‚ Computer
