A network of interconnected self-service machines (SSMs), wherein each of the SSMs executes a relational database management system (RDBMS) that maintains a relational database stored on the SSM. The relational databases are partitions of a global relational database and each partition stores information for only those customers that frequent the SSM that executes the RDBMS. The relational databases are used to more effectively serve the customer at the SSM and to market products and services to the customer at the SSM.
