Chapter 5.1: The Siloed Application Environment
           Most of these siloed applications were the very first applications that were built or were
           otherwise acquired by the corporation. As a result, these were the very first applications
           that inhabited the corporation.


           In many cases, these applications were the applications that directly connected the
           corporation to its customers. Typical of these applications were ATM processing, bank
           teller processing, airline reservation processing, and so forth. These early applications

           were critical because they were the day-to-day face of the corporation to its customer
           base.


           These early applications had a direct effect on the day-to-day business of the corporation.
           For example, when the bank teller system went down, the bank had to cease doing
           business until the system came back up.


           Current Valued Data



           One of the common expectations was that the data found in the application were what

           can be called “current valued data.”
