Object oriented databases have been around since the late 1980’s. Object oriented programming languages have been around since the sixties. Today the need for object oriented databases is growing along with the complexity of the software systems developed. There are today a number of object oriented databases available on the market. The apabilities and properties of the systems are covering a wide range, making the choice of system difficult to the developer. This thesis presents a guideline for evaluating object oriented database management systems to be able to compare different systems and chose which one to use. / anders@actk.net
