With an experimental object-oriented database system (OODBS), the representation and retrieval of material testing data are attempted. In many cases, the matching fails between query and data objects which appear quite natural and understandable in human's viewpoint, yet missing many necessary entries in computer's viewpoint. Causes of the missing entries are discussed and methods are presented to supplement them by the default reasoning and the similar inference which embody expert knowledge. The inferences as such will play a vital role in the practical use of OODBS in many domains to make its rich expressive power and the performance of data retrieval compatible.
