每当多个用户或程序并发访问数据库时，就会出现并发控制问题。问题是同步并发交互，以便每个交互从数据库读取一致的数据，写入一致的数据，并最终处理完成。在分布式数据库中，由于一个站点上的并发控制机制无法即时了解其他站点上的交互，因此这个问题更加严重。迄今为止，关于这一主题的论文不下30篇。我们的目的是调查这些文献，集中在三种方法——锁定、多数共识和SDD-1协议——它们一起包含了大部分文献。**
Whenever multiple users or programs access a data base concurrently, the problem of concurrency control arises. The problem is to synchronize concurrent interactions so that each reads consistent data from the data base, writes consistent data, and is ultimately processed to completion. In a distributed data base this problem is exacerbated because a concurrency control mechanism at one site cannot instantaneously know about interactions at other sites. No fewer than 30 papers on this topic have appeared to date. Our purpose is to survey this literature, concentrating on three approaches—locking, majority consensus, and SDD-1 protocols—which together subsume the bulk of the literature. **
