Transaction management is a known crosscutting concern. Previous research has been conducted to express this concern as an aspect. However, such work has used general-purpose aspect languages which lack a formal foundation, and most importantly are unable to express advanced models of transaction management. In this paper, we propose a domain-specific aspect language for advanced transaction management, called KALA, that overcomes these limitations. First, KALA is based on a recognized formalism for the domain of advanced transaction management, called ACTA. Second, as a consequence of being based on the ACTA formalism, KALA covers a wide variety of models for transaction management. Finally, being a domain-specific aspect language, KALA allows programmers to express their needs at a higher level of abstraction than what is achieved with generalpurpose aspect languages. This paper reports on the design of KALA and its implementation over Java, based on the Reflex AOP kernel for dom...
