Data Validation

Most applications devote less than 10% of their code to the overt function of the system; the other 90% goes into system or administrative code: input and output; user interfaces, text editing, basic graphics, and standard dialogs; communication; data validation and audit trails; basic definitions for the domain such as mathematical or statistical libraries; and so on.
