This section provide help on creating, deleting and editing data binds.
The Data Binding widget enables you to create, delete and edit data binds.
What is a Data Bind?
A Data Bind associates a spatial table with a non-spatial table or a spatial table
using a common column between the two tables. For example, a property boundary table may
have a property ID column. A non-spatial table (for example, Animal Registrations) may
also refer to the same property IDs. Now, when you look for the information for a
property, in addition to the columns in the property table (Address, Postcode etc.) you
would also see the animal registrations at that property (like, Species, Breed,
Registration Date etc.). There may be multiple animal registrations at a property hence
the relationship is one to many. A data bind allows you to:
- display a wide range of relevant attribute data from associated tables without having to add each one as a map layer (especially as they would all share the same geometry).
- query the associated table at source so that admins do not need to bring the associated tables into the web mapping system to create a join.
