| Abstract | Software components are still considered the weakest link when it comes to addressing reliability of a system. We argue that a systematic application of Bertrand Meyer's design by contract methodology improves reliability quite significantly. In the perspective of design by contract methodology, reliability is viewed as correctness and robustness. The concept of Reliability by Construction is dealt with in detail. Process steps to introduce or integrate design by contract methodology into existing SDLC of a product or system are discussed. The notion of sufficiently strong contracts is dealt with along with their advantages in defect prevention. Composition of function calls or services and the properties that contract specifications of successive functions(calls) need satisfy are stated. The process of contract refinement during successive phases of SDLC is discussed. Contract specification rules in the presence of inheritance in object-oriented programs are also discussed. Finally, we argue that design by contract methodology aids in zero-defect programming. |

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.
