Abstract
Well defined concurrent replicated data structure is very important to design collaborative editing system, particularly, certain properties like out-of-order execution of concurrent operations and data convergence. In this paper, we introduce novel linear data structure based on unique identifier scheme required for indexed communication. These identifiers are real numbers holding specific pattern of precision. Based on the uniqueness and the total order of these identifiers, here, we present two concurrency control techniques to achieve high degree of concurrency according to strong and lazy happened-before relations. Our data structure preserves data convergence, yields better performance and avoids overheads as compared to existing approaches.
