| Abstract | A database grid can provide a robust distributed environment for accessing and manipulating different database resources. While current challenges focus on managing database resources and ensuring the quality of data integration. This paper describes a service level agreement (SLA) based data integration model, which includes SLA-based resource description model, SLA-based query model, SLA-based matching algorithm and SLA-based evaluation model. The SLAs of a database resource is defined by SLA-based resource description model. The SLA-based query model is defined to normalize the various types of queries. The SLA-based matching algorithm has been proposed to match schemas of resources for each sub-query, and then the quality of database resources is evaluated by SLA-based evaluation model to obtain the final query solutions. Experimental results have shown that SLA-based data integration model can provide more stable database resources and save time cost in data integration applications as well. |

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.
