Lock-free consistency control for web 2.0 applications

Jiangming Yang, Haixun Wang, Ning Gu, Yiming Liu, Chunsong Wang, Qiwei Zhang
2008 Proceeding of the 17th international conference on World Wide Web - WWW '08  
Second, locking will block a large portion of concurrent operations, which makes it impossible to provide large-scale availability.  ...  On the other hand, most Web 2.0 operations do not need strict serializability -it is not the intention of a user who is correcting a typo in a shared document to block another who is adding a comment,  ...  But in a distributed environment, it is difficult to implement a global, precise clock that informs each site the precedence of operations.  ...

Correctness Criteria Beyond Serializability [chapter]

Mourad Ouzzani, Brahim Medjahed, Ahmed K. Elmagarmid
2017 Encyclopedia of Database Systems  
A schedule S is serial if for every two transactions T i and T j that appear in S, either all operations of T i appear before all operations of T j , or vice versa.  ...  SYNONYMS Concurrency Control; Preserving Database Consistency DEFINITION A transaction is a logical unit of work that includes one or more database access operations such as insertion, deletion, modification  ...  A concurrent schedule of transactions is conflict equivalent to a serial schedule of the same transactions (and hence conflict serializable) if they order conflicting operations in the same way, i.e.,  ...
