Database 133
Appendix C: Database
The database contains six datapoint types. Each datapoint type represents a specific data format: whole
integers, alphanumeric text strings, etc. The datapoint types are defined in Table C-1. The database is
listed in alphanumeric order in Table C-2. The gray-tone shading in the default cell of a datapoint indicates
the datapoint contents are not changed by defaulting the database. (For the procedure to default the dat-
base, see Section 3.3.3, Defaulting the Database.)
