Programming with transactions and chemical abstract machine

The coordination style programming language T-Cham extends chemical abstract machine (Cham) with transactions. The Cham is an interactive computational model based on chemical reaction metaphor, where a computation proceeds as a succession of chemical reactions. A transaction is a piece of sequentially executed codes and could be written in any language, such as C, Pascal, or Fortran etc., as long as it satisfies its pre-condition and post-condition. Every transaction begins its execution whenever its execution condition is satisfied. A T-Cham program can be executed in a parallel, distributed, or sequential manner based on the available computer resources
