What is the difference between local and global complexity?

[dvberkel]

1. Global complexity describes interactions inside a component, and local complexity is the complexity of interactions between components.
2. Local complexity describes interactions inside a component, and global complexity is the complexity of interactions between components.
3. Global and local complexities are synonymous in the context of software design
4. Global complexity results from the use of global variables, while local complexity relates to to local fields

[dvberkel]

Complexity is not a description of how variables are used, but a describes a system. This excludes option 4.

[dvberkel]

Global and local complexity are not synonymous, but are depend on context.

This also excludes option 3.

[dvberkel]

This leaves option 1 and 2 that only differ in which adjective is coupled with which noun.

On page 40 the definitions of the terms global- and local-complexity are given. This agrees with option 2.
