Exact information has become crucial part of the modern database applications and next generation information systems to make them more human friendly. In order to deal with information inexactness, fuzzy techniques have been extensively integrated with different database models and theories. But, object oriented database systems are extremely capable to represent and manipulate the complex objects as well as complicated and uncertain relationship existing among them. They are also much suitable for engineering and scientific applications, dealing with large data intensive applications. In this paper, a survey of different approaches regarding integration of fuzzy techniques in object oriented databases has been sketched, under numerous categories of conceptual data modeling, querying, indexing etc.
