Abstract

We survey, in this paper, global concurrency control strategies for heterogeneous distributed database systems. We focus on the issues of consistency, local autonomy and performance. According to whether a strategy prevents or resolves inconsistency, it is classified into one of the two basic approaches: optimistic or pessimistic. The former intends to provide a high degree of concurrency among global transactions, while the latter is concerned with aborts of global transactions. The strengths and weaknesses of the two approaches are discussed.
