| Abstract: | In this article, we first point out the key technologies in the design of MMDBMS based on the analysis of its architecture. The key subject of this article is the abstraction and indexing of features of multimedia objects. About the feature abstraction, the overview of the current state of the research in this domain is discussed. About the indexing of features, a data structure MIX-TREE that suits the MMDBMS is proposed under the background of the existedmultidimensional indexing structures. |
