Catalog Database Structure

This chapter details the structure of the PDMS Catalog database.

Note: Words of four or five uppercase characters which appear in this chapter (for example, CATA, BLTA, SPREF) are PDMS element names. When an element’s member list is queried in PDMS, each element type will be displayed as a four-character name. Five or six characters are occasionally used in this chapter where this gives an ‘PDMS’ name which is closer to the element’s ‘English’ name, for example SPREF (instead of SPRE) for Specification Reference.
