These are WID tables, their history and data sources. Tables can come in 4 types –
Lookup Tables – these define the codes used to describe data types in data tables
Data Tables – these contain the data for various sources
Crosswalk Tables – these relate different data structures
Admin Tables – these describe the tables in the database
While Core (required) tables have complete content, non-standard (not required) tables may not. If you have questions that are not answered by the documentation, try asking in our forum or emailing Amanda.
