Globals are multidimensional sparse arrays which are stored in InterSystems Data Platform. Everything in InterSystems Products is stored in Globals: Classes, Tables, Documents, Code.
My team lead mentioned that users can sometimes create globals directly without associating them with tables or classes. In this case, these globals would not be accessible via SQL.
Is this correct? Can a global exist independently in this way, and if so, is there a specific approach to access or manage them without SQL?
