Introducing CEDA

CEDA is a high performance database technology that uses Operational Transformation (OT) to support replication and synchronisation for collaborative data entry performed by multiple users. CEDA is an ideal platform for Computer Supported Collaborative Work (CSCW), allowing multiple users to edit that same data concurrently. Users can collaborate in a interactive, realtime manner or work offline and control when changes are propagated to/from other users.

CEDA provides an application development platform for building applications that support collaborative work. Application developers can easily build multiuser applications based on CEDA that are as responsive as single user applications while attaining benefits of realtime interactive collaboration and sophisticated version control. The platform allows for branching and merging of the entire database, supporting manual check-ins, check-outs, updates, tagging and so forth in a similar manner to source code repository systems like ClearCase and Subversion.

The OT algorithms employed by CEDA are extraordinarily efficient, allowing users to work off line for long periods of time and then quickly synchronise with other users.

This paper provides an introduction to CEDA and some of the platforms features.
