| Abstract | Summary form only given. Process of information system development consists of several phases including, in particular, system analysis, specification, design, and implementation. Each of these phases is based on some abstractions that can be roughly divided into two groups of general and specific abstractions respectively. In this talk we address to such general abstractions as intensionality, compositionality, and nominativity. Intensionality is understood in the traditional sense as a counterpart to extensionality that together complete each other and define the main aspects of notions in their integrity. Compositionality means that a system is constructed of smaller subsystems with the help of special construction operations called compositions. Nominativity emphasizes the importance of naming relations for system aspects description. We analyze and illustrate the use of the above mentioned abstractions in different phases of system development. Considering conventional mathematical formalisms we admit that they are based on the extensionality principle that restricts and complicates usage of such formalisms in system development. Therefore we construct formal mathematical structures based on the principles of intensionality, compositionality, and nominativity. These structures can be considered generalizations of traditional notions of algebras and logics for classes of "dynamic" data and functions. Introduction of such formalisms permits us to define also a special kind of intensionalized computability that better reflects specifics of executable components of information systems. We compare the constructed formalisms with the existing ones and demonstrate that they a rather expressive and more adequate for information system development. |

| Resource Type | Synopsis |
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.
