We present a generalization of existing algorithms for simple global query modification that works for arbitrarily defined integration classes. We then extend this algorithm to deal with object-oriented features that have been neglected in literature, viz.\u00a0queries involving path expressions and nested queries. We show how properties of the OO-style of modeling relationships through object references can be exploited to reduce the number of subqueries necessary to evaluate such queries. <\/jats:p>","DOI":"10.1142\/s0218843097000112","type":"journal-article","created":{"date-parts":[[2003,10,15]],"date-time":"2003-10-15T02:51:31Z","timestamp":1066186291000},"page":"219-240","source":"Crossref","is-referenced-by-count":0,"title":["Modifying Queries on Complex Objects in Database Federations"],"prefix":"10.1142","volume":"06","author":[{"given":"Mark.
