Figure 5.1 A View of ILOG CPLEX in ILOG Concert Technology

Figure 5.1 illustrates the design of ILOG Concert Technology and how a user-application uses it. ILOG Concert Technology defines a set of interfaces for modeling objects. Such interfaces do not actually consume memory. (For this reason, the box in the figure has a dotted outline.) When a user creates an ILOG Concert Technology modeling object using ILOG CPLEX, an object is created in ILOG CPLEX to implement the interface defined by ILOG Concert Technology. However, a user application never accesses such objects directly but only communicates with them through the interfaces defined by ILOG Concert Technology.
