Abstract
A storage method and a search method for mark events on two-dimensional space are provided. First, an event and a corresponding coordinate thereof are retrieved. Next, calculation on the coordinate of the event is performed to generate an index representing a bucket position in a storage device. Next, whether or not there is any existing search tree stored in the bucket position is judged, and then the event is inserted into a linked list of a node of the search tree stored in the bucket position according to a judgment result. Besides, when a range on the two-dimensional space is designated, corresponding nodes in the search tree are rapidly accessed according to the index obtained by a hash function, and further by application of pointers pointing to the bucket position having the search tree stored therein and by real-time return of search result, the search speed is high.
