Abstract
We present, in this paper, a scheduler that generates quasi serializable executions. Quasi serializability is a new correctness criterion for concurrency control in heterogeneous distributed database systems (HDDBSs). The scheduler differs from the previous ones in that it controls the submission and interleaving of global transactions only. Therefore. it does not violate local autonomy. In addition, it provides a high degree of concurrency and is global deadlock free. All the features make it very attractive for HDDBSs.
