This paper presents an m-array based indexing scheme for efficient retrieval on FLOWR queries on XML databases. The proposed technique stores path dictionary, element dictionary and value node dictionary using B+tree structure. With help of this method we can access database quickly and effectively...

For this reason, a hybrid spatial index method combining octree and R*-tree [12] to organize Point Cloud data is proposed. 2. Related Work 2.1. Single Indexing Structure With the widely utilized of 3D sensors, the volume of Point Cloud data is increasing dramatically. Point Cloud data ...

We propose the application of graph database as an indexing layer that defines conceptual linking between database entities, beside logic-based assertions and constraints to evaluate XML queries over this layer to find most related entities and traverse only their related nodes in the XML document....
