| Abstract: | The partial relations of distributed operations and the consistency model are introduced and analyzed. Based on the development of typical operational transformation algorithms, basic operational transformation functions are discussed and summarized. The intention problems are carefully analyzed and the algorithm guides for intention preservation are presented. Open issues and future research directions are also discussed. |
