| Abstract | Most large-scale applications integrate remote services and/or transactional databases. Yet building software that efficiently invokes distributed service and accesses relational databases is still quite difficult. Existing approaches to these problems are based on the Remote Procedure Call (RPC) and Object-Relational Mapping (ORM). RPCs have been generalized to distributed object systems with remote proxies, a kind of remote object reference. ORM tools generally support a form of query sub-language for efficient object selection. The last 20 years have produced a long litany of technologies based on these concepts, including ODBC, CORBA, DCE, DCOM, RMI, DAO, OLEDB, SQLJ, JDBC, EJB, JDO, Hibernate, XML-RPC, Web Services and LINQ. Even with these technologies, complex design patterns for service facades and/or bulk data transfers must be followed to optimize communication between client and server or client and database, leading to programs that are difficult to modify and maintain. While significant progress has been made, there is no widely accepted solution or even agreement about what the solution should look like. In this talk I present a new unified approach to invocation of distributed services and data access. The solution involves a novel control flow construct that partitions a program block into remote and local computations, while efficiently managing the communication between them. The solution does not require proxies or an embedded query language. Although the result itself is elegant and useful, what is more significant is the realization that the original problems cannot be solved using existing programming language constructs and libraries. This work calls into question our assumption that general-purpose programming languages are truly general-purpose. |

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.
