| Abstract | Presents a multiversioning scheme for a distributed system with the workload consisting of read-only transactions and update transactions, (most of) which commute on individual nodes. The scheme introduces a version advancement protocol that is completely asynchronous with user transactions, thus allowing the system to scale to very high transaction rates and frequent version advancements. Moreover, the scheme never creates more than three copies of a data item. Combined with existing techniques to avoid global concurrency control for commuting transactions that execute in a particular version, our multiversioning scheme results in a protocol where no user transaction on a node can be delayed by any activity (either version advancement or another transaction) occurring on another node. Non-commuting transactions are gracefully handled. Our technique is of particular value to distributed recording systems where guaranteeing global serializability is often desirable, but rarely used because of the high performance cost of running distributed transactions. Examples include calls on a telephone network, inventory management in a "point-of-sale" system, operations monitoring systems in automated factories, and medical information management systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
