1. A computerized method for representing the connectivity of Web pages, the Web pages including links between the Web pages, the links and Web pages being identified by names, comprising: sorting the names of the Web pages in a memory; delta encoding the sorted names while periodically storing full names as checkpoints in the memory, each delta encoded name and checkpoint having an assigned unique identification; twice sorting a list of pairs of identifications that represent the links between the Web page, each pair of identifications including a first identification and a second identification, first according to the first identification of each pair to produce an inlist, and second according to the second identification of each pair to produce an outlist; storing an array of elements in the memory, there being one array element for each Web page, each element including a first pointer to one of the checkpoints, a second pointer to an associated inlist of the Web page, and a third pointer to an associated outlist of the Web page; and indexing the array by a particular identification to locate connected Web pages.

The method of claim 1 further comprising receiving the name of a particular Web page, searching the checkpoints to locate a closest checkpoint, scanning the delta encoding names from the closest checkpoint to obtain the unique identification associated with the particular Web page, and indexing the array by the unique identifications to obtain the inlist and outlist of the particular Web page.
