The DRMS code is implemented using the PostgreSQL database system. Names used for series, keywords, links, and segments are also used as table or column names in the database code. The DRMS names can not collide with PostgreSQL reserved names. The list of the reserved names that can not be used in DRMS jsd files is found at http://www.postgresql.org/docs/8.2/interactive/sql-keywords-appendix.html and extracted below:
