Abstract:
Now m ost o fm ethods o f translating re la tiona l schem a to XML schem a cannot rem ain in trins ic sem antic inform ation o f relationa l database. This paper is based on the research for th is problem and presents a semantic based translating a lgor ithm th rough denorm a liza tion. Re lational schem a arem apped to relationa l cha rt. Tab le sets in acco rdancew ith the jo ining cond itions are ob tained from the chart. Assoc ia ted tables are jo ined accord ing to the classification, and seve ra l sim ple structure relationsh ips are replaced by a com plex one. Acco rd ing to the data dependent re lationship, an XML schem a is created for every jo ined tab le and disjo ined table. A ll schem as are integrated into one. Exper im ents show that the algorithm is v alid and effic ient fo r keep ing sem an tic restriction and strengthen ing coupling
