The advent and widespread use of Enterprise JavaBean (EJB) technology not only demands more reengineering support for legacy database applications, but also changes the reengineering practice. Initiated from our experience of reengineering database applications to EJB based architecture, this paper addresses two challenges in the mapping between database queries and EJBs. The first is to map a SQL to the equivalent EJB client code when the enterprise beans exist. The second is to generate enterprise beans from the set of legacy SQL expressions when the EJB architecture does not exist in the first place. We propose the EJB-SQL mediator to solve the first problem, and a view selection algorithm to solve the second one.
