BEX supports a notation where an expression is written using simple variables followed by the attributes they represent. For example, assume the following expression is used in Java:
(Agreed Value of the vehicle - Market Value of the vehicle) / Market
Value of the vehicle is more than Limit Defined By
User
As can be seen from the example, the expression is hard to read. However, the expression is much simpler if written according to the notion of explanatory variables as follows:
(A - M) / M > X, where
A - Agreed Value of the vehicle,
M - Market Value of the vehicle,
X - Limit Defined By User
This syntax is similar to the one used in scientific publications and is much easier to read for complex expressions. It provides a good mix of mathematical clarity and business readability.
