B.2.2 Bound Variables

Use an extension on bindings that are computed or derived from other variables and attributes that describes the type of information it is capturing. Use the same naming conventions applied in the database:

• o_Ct = Count
• o_Qt = Quantity
• o_Am = Amount
• o_Pt = Percent
• o_Rt = Ratio

Variable names should describe the purpose of the variable as clearly as possible.

In the Sequence Matcher, the focal entity must be bound to a variable with the focus name (for example, ACCOUNT). Do not use the name of any focus type under any other circumstances as a binding name for other purposes.
