SEST L : An Event-Oriented Spatio-Temporal Access Method ⁄
Gilberto Gutiérrez, Gonzalo Navarro, Andrea Rodr ́ iguez · 2006
This work presents a new access method (SESTL) that handles discrete change events over objects ’ spatial attributes. The access method combines snapshots and events in log structures associated with space partitions. The definition of this new access method aims at extending capabilities of current spatio-temporal access methods to new types of queries (i.e., event-oriented queries), while competing with current structures for traditional time-slice and timeinterval queries. The paper describes the structure and presents favorable analytical and experimental cost analysis of the structure. 1
