Transaction Engine

The best way to think of the transaction engine is as a suite of applications for its different users: buyers, sellers, and operators. This model is shown in Figure 21-5. In more traditional business settings, buyers interact directly with sellers, and both interact directly with operations and support groups. On the Internet, the situation is different because the parties involved are rarely online at the same time. Instead, each group of users interacts with applications that place their retained state in a database where the next group can pick it up and carry on. The database, without loss of generality, can be a set of databases with workflow capabilities.
