The molecule of the title compound, C17HIlC104S, contains three nearly planar segments (the benzopyranone group, the chlorophenyl ring and the ethene group with its immediate substituents). The sulfonyl plane is inclined at 60.3 ° to the plane of the ethene moiety and at 51.5 ° to the plane of the benzopyranone group. CommentThe crystal structure of the title compound, (I), has been determined as part of a series of studies of the stereochemistry of sulfones containing ethene and benzopyran groups. These compounds are effective fungicides (Hawthorne, 1960).

In this modern world, travelling has become as normal routine for most of the people in the cities. At the same time, frequency of happening of accidents also increasing alarmingly. Also one cannot avoid health care and should take proper health checks in hospitals periodically. At the time of accidents, to save precious lives, we must know better hospitals nearby. In that context, in this paper X-tree [1] structure has been implemented for multidimensional data ranking. Problem definition is explained in section1, importance of X-tree is explained in section2, Proposed System explained in section3, Advantages of Proposed system explained in Section 4, Implementation and sample data are explained in sections 5 and 6, module description and other constraints have been explained in the remaining sections.
