Originally, SOCI was developed by Maciej Sobczak at CERN as abstraction layer for Oracle, a Simple Oracle Call Interface. Later, several database backends have been developed for SOCI, thus the long name has lost its practicality. Currently, if you like, SOCI may stand for Simple Open (Database) Call Interface or something similar.
"CERN is also a user of the SOCI library, which serves as a database access layer in some of the control system components."
