MARC and relational databases

MARC format is a well‐established syntax for transmitting bibliographic records between heterogeneous computer systems. On the other hand, relational databases are the leading technology for the design of the computer systems. Unfortunately, there seem to be some incompatibilities between the two. A solution is presented here, in accordance with the more recent standards about Open System Interconnection (OSI) and based on a real experience in an active library computer system.
