The global paleomagnetic database: Current status



The Global Paleomagnetic Database (GPMDB) is a data base for paleomagnetic directions and pole positions. It was first compiled by Lock and McElhinny [1991] and made use of the PC version of the Oracle Database Management System, which at the time was the only PC system available that used SQL, the internationally recognized language for use with database management systems. Subsequently, the Oracle PC system became far too large and complex for the GPMDB, so the data base was transferred to Microsoft Access, which had just become available and also used SQL [McElhinny and Lock, 1996].
