re 28 Example for Calculating the Number of Relationships
According to Figure 28 on page 62, the total number of resources used per pair is c alculated as:
Resources used for A − H=(3+1)+1+ 1+1+1+ 1+(9x3)+9+ 9=54.
The conditions for the number of relationships you can create are:
Σ(α) ≤ (β)and Σ(γ) ≤ 1,048,575
In the case of the example shown in Figure 28 on page 62, Σ(α) ≤ (β)is:
• 54 ≤ 26,176 or 57,600, or 104,768, or 146,688, or 209,600
