Abstract | The Object-Oriented Functional Data Language (O/sup 2/FDL), an interactive, strongly typed database programming language, is discussed. It features inheritance and encapsulation of object-oriented languages and a functional notation for message expressions. The main contributions of the O/sup 2/FDL are: (1) functions of indefinite nesting levels that simplify nested list processing and form the basis of an efficient computation model; (2) path expressions that allow a flexible, graphical correspondence for database queries; (3) a type system featuring parametric and inclusion polymorphism, function restrictions, and type inferencing; and (4) system-defined functions that provide a concise and convenient notation for filtering aggregating, and combining objects. The versatility of the O/sup 2/FDL is demonstrated here for both relationally-complete expressions and more general computations.< |

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.
