By Georg Lausen, Dan Suciu

The papers during this quantity symbolize the technical software of the ninth Biennial WorkshoponDataBasesandProgrammingLanguages(DBPL2003),whichwas hung on September 6-8, 2003, in Potsdam, Germany. The workshop meets each years, and is a well-established discussion board for ideas that lie on the intersection of database and programming language examine. DBPL 2003 endured the t- dition of excellence initiated by way of its predecessors in Rosco?, Finistre (1987), S- ishan, Oregon (1989), Nafplion, Argolida (1991), long island, manhattan (1993), Gubbio, Umbria (1995), Estes Park, Colorado (1997), Kinloch Rannoch, Sc- land (1999), and Frascati, Rome (2001).

The language is dependent round an easy but robust notion: it has special information forms, relatives and streams, with well-de?ned operators for mapping among them. Window speci?cation expressions, similar to sliding home windows, map streams to relatives, whereas operators resembling ’’insert stream,’’ ’’delete stream,’’ and ’’relation stream’’ map kin to streams by way of returning, at each one second in time, the newly inserted tuples, the deleted tuples, or a image of the total relation. the varied examples during this paper make a resounding case for the facility and value of CQL

5 String Matching Problems In order to show the hardness of deciding satisfiability for certain XPath fragments we will show that the following string matching problem can be reduced to these problems. Definition 8 (Bounded Multiple String Matching Problem). Given a finite set of patterns A, which are strings over is there a string over {0,1} whose size is equal to the size of the largest pattern in A and in which all patterns in A can be matched with as a wildcard for one symbol? In the following we will also refer to this problem as the BMS problem.

Proof. We show that the BMS problem can be reduced to this problem. We assume that the set of patterns is and that is the longest pattern. The pattern is translated to a path by translating a 0 to 1 to and to just For example, “*0*0*1” is translated to The other patterns are translated to in the same way but with an extra step before and after it. So, for example, “10” is translated to Finally we take the intersection of all these paths: It is easy to see that if there is an XML tree T and a pair in the semantics of this path under T then labels of the nodes in the path from to represent a string into which all patterns match if we replace and with 1 and 0, respectively.
