MARC (MAchine
Readable Coding)
- The underlying and most important
standard for electronic (online) library catalogs and
bibliographic databases.
- MARC basically provides a
more-or-less standard format for machine- (read "computer")
readable descriptive, cataloging, and locational bibliographic
data about books and other media.
- MARC structures bibliographic
records in a way that facilitates their access by search and
retrieval software.
- There are several implementations
of MARC, including the Library of Congress's USMARC (former
LCMARC), OCLC's variant, and international variants.
SQL (Structured
Query Language)
- A standard database access and
retrieval technology for many of what are called "relational"
database management systems (DBMSs).
- SQL-compliant DBMSs (such as
Oracle and Sybase) are sometimes used to provide the underlying
database structure in library automation systems.
