Abstract | This paper surveys the recent literature about various research trends relevant to Relational DataBase (RDB) reengineering. The paper presents an analysis of approaches and techniques used in this context, including construction of object views on top of RDBs, database integration and database migration. A categorisation is presented of the selected work, concentrating on migrating an RDB as a source into object-based and XML databases as targets. Database migration from the source into each of the targets is discussed and critically evaluated, including the semantic enrichment, schema translation and data conversion. Based on a detailed analysis of the existing literature, it seems that the existing work does not provide a complete solution for more than one target database for either schema or data conversion. Besides, none of the existing proposals can be considered as a method for migrating an RDB into an object-relational database. We propose such a method based on an intermediate canonical data model, which enriches the semantics of the source RDB and captures characteristics of the target databases. |

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.
