Q

What is the difference between global scope vs private scope apps?

A

Global is “The Wild West”. There is easy access to anything from anywhere and it’s hard to isolate and protect applications. Scoped is “Civilized Society”. Universally enforced namespace, contextual development, runtime application separation, installation and un-installation, public and private API definitions, table level data access control, dependency tracking. In the baseline case, custom applications have read access to each other’s table records but cannot perform any other database operations.
