Document IndexingIndexing & Cataloging

Indexes are used to quickly and efficiently provide the exact location of the corresponding data. An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by allowing indices to be created on functions or expressions.Database Index

Cataloging (or cataloguing) is the process of listing something for inclusion in a catalog. In library and information science, the process encompasses the production of bibliographic descriptions of books as well as other types of discovery tools for documents. Today cataloging study and practice has broadened and merged with that of metadata (“data about data contents”), increasingly associated with Resource Description and Access.[1]
