Section 2.2 General Overview of Relationships

The following tables provide the general relationship between the ‘data’ tables (i.e. those prepended with a ‘D_’) and the ‘reference’ tables (also known as the ‘look-up’ tables; prepended with a ‘R_’) within the database (Table 2.2.1). Additional ‘web’ tables (prepended with a ‘W_’) contain a weekly summary of information as found within the database by location. These are used as the source for all web-based mapping.

Note that, for the second table (Table 2.2.2), any listed key in the second ‘Key’ column implies a change in the name of the field between the related tables.

Table 2.2.1 Table relationships between the data (D_) and web (W_) tables using LOC_ID and INT_ID keys.

Table 2.2.2 Table relationships and associated keys for all other tables (excluding data and web tables)
