As in conventional database management systems (DBMSs), to allow users to efficiently access and retrieve data objects, a multimedia database management system (MMDBMS) must employ an effective access method such as indexing and hashing. This paper provides a survey of tree-based multidimensional ...

An example of the use of domain indexing would be the use of R-tree indexes for spatial data. A domain index is based on the concept of an INDEXTYPE, which, like a User Defined Type (UDT), is created and maintained by the user. In order to use a domain index, a data cartridge ...

A tree-based trylock technique for reducing contention on a root trylock includes attempting to acquire a trylock at each node of a tree-based hierarchical node structure while following a traversal path that begins at a leaf node, passes through one or more of internal nodes, and ends at a...
In this paper, we propose a new method for indexing large amounts of point and spatial data in high-dimensional space. An analysis shows that index structures such as the R*-tree are not adequate for indexing high-dimensional data sets. The major problem of R-tree-based index structures is...
