global number VS global calculation

[nangko]

Hi,

 

I often define global values that don't need to be changed as a calculation.

I use this often for defining relationships. (for example a "0" key for defining an OR relation).

 

I store the "0" as a calculation. So I can only change this value if I manage the database. And I don't need to create a form field first to give the global field a value.

 

But what is better for DBPerformance? a global number field with the value "0" or a global calculation field with the calulation "0"?

Global number i think.

Because global number have not place in all records and file have less size.
