....of nodes or paths, as the basic unit of query. Through sequence matching, we match structured queries against structured data as a whole, without breaking down the queries into sub queries of paths or nodes and relying on join operations to combine their results. Many XML databases, such as DBLP [15] and the Internet movie database IMDB [22] contain a large set of records of the same structure. Other XML databases may not be as homogeneous. A synthetic XMARK [23] dataset consists of one (huge) record. However, each sub structure in XMARK s schema, items, closed auction, open auction, person, ....
....time we descend from a parent node to a child node. As a result, the size of t i s scope comes to Max # , where Max is the size of the root node s scope. Apparently, for a large enough i, Max # 0. This problem is called scope underflow. As we have mentioned, XML databases such as DBLP [15] and IMDB [22] are composed of records of small structures. For databases with large structures, such as XMARK [23] we break down the structure into small sub structures, and create index for each of them. Thus, we limit the average length of the derived sequences. If scope underflow still ....
