arnobrinkman	710037031f	Enhanced Index Structure. ... 1) NULLs on top when sorting on ASC index, DESC stays the same. 2) Support for larger index lengths, can be up to 1/4 page size. 3) Store record-number on non-leafpages for faster lookup in many duplicates. 4) Jump-nodes for faster key-lookup in index on larger page-sizes. 5) Segment selectivity calculation added.	2003-12-01 02:37:25 +00:00
