Q. Explain Information Flow index?

Information Flow index Information flow metrics are practical to the components of a system design. For any component A We are able to define three measures

1: FAN IN is merely a count of the number of other components that can all or pass control to component A.

2: FAN OUT is the numeral of components that are called by component A.

3: using the subsequent formula derives this. We will call this measure as the INFORMATION FLOW index of component A abbreviated as IF(A).

IF (A) = {FAN IN(A) *FAN OUT (A)}2
