Implementing an EJB3-Specific Graph Transformation Plugin by Using Database Independent Queries

Download www.cs.bme.hu

The current paper presents a novel approach to implement a graph transformation engine as an EJB3-specific plugin by using EJB QL queries for pattern matching. The essence of the approach is to create an EJB QL query for the precondition of each graph transformation rule. Pattern matching and updating phases of a rule application are implemented in a public method of a stateless session bean by executing the prepared EJB QL query and by manipulating persistent objects, respectively. Key words: graph transformation, EJB 3.0, EJB QL queries.
