| Abstract | Immortal DB is a transaction time database system that is built into a commercial database system rather than being layered on top. This enables it to have performance that is very close to the performance of an unversioned current time database system. Achieving such competitive performance is essential for wide acceptance of this temporal functionality. In this paper we describe further performance improvements in two critical dimensions. First Immortal DB range search performance is improved for current time data via improved current version storage utilization, making this performance essentially the same as unversioned performance. Second, Immortal DB update performance is increased by further reducing the cost for the timestamping of versions. Finally, we show how a simple modification, integrated into the timestamping mechanism, can provide a foundation for auditing database activity. Our algorithms have been incorporated into a commercial database engine and experiments using this database engine demonstrate the effectiveness of our approach. |

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.
