Black Box Concept

1. This chapter describes a black box (see below) concept that allows more detail to be shown as a process is exploded. Can the concept be applied in business management generally, or is it limited to information systems design? Provide reasons and examples with your answer. *In data flow diagrams (DFDs), a process symbol can be referred to as a black box, becase the inputs, outputs, and general funcions of the process are known, but the underlying details and logic of the process are hidden. By showing processes as black boxes, an analyst can create DFDs that show how the system functions, but avoic unnecessary detail and clutter.*

I am attempting to complete Assignemt Exercise 13.12 in the Deitel&Deitel 5th edition version of C++ How to program. I am running into some early errors in trying to incorporate the Date class into the existing Employee inherited class heirarchy. One issue is that I'm getting erros in the dervied classes that there are virtual functions in derived classes that have non-virtual destructors. I'm not sure what is going on at this point.
