Question 1 :
Write short notes on :
Operations as Transformation Systems :
Answer :
Operational transformation is a technology for supporting a range of collabouration functionalities in advanced collabourative software systems. OT was originally invented for consistency maintenance and concurrency control in collabourative editing of plain text documents. Two decades of research has extended its capabilities and expanded its applications to include group undo, locking, conflict resolution, operation notification and compression, group-awareness, HTML/XML and tree-structured document editing, collabourative office productivity tools, application-sharing, and collabourative computer-aided media design tools.
Operational Transformation was pioneered by C. Ellis and S. Gibbs in the GROVE (Group Outline Viewing Edit) system in 1989. Several years later, some correctness issues were identified and several approaches were independently proposed to solve these issues, which was followed by another decade of continuous efforts of extending and improving OT by a community of dedicated researchers. In 1998, a Special Interest Group on Collabourative Editing (SIGCE) was set up to promote communication and collabouration among CE and OT researchers. Since then, SIGCE holds annual CE workshops in conjunction with major CSCW (Computer Supported Cooperative Work) conferences, such as ACM CSCW, GROUP and ECSCW.
Collabourative systems using OT typically adopt a replicated architecture for the storage of shared documents to ensure good responsiveness in high latency environments, such as the Internet. The shared documents are replicated at the local storage of each collabourating site, so editing operations can be performed at local sites immediately and then propagated
