|Abstract||The complexities of Retail Business Systems today require a thorough understanding of how functional requirements impact desired system performance. It is no longer feasible to discretely test and evaluate individual system components without considering their inter-relationship. The techniques described in this presentation will define the method of system characterization of products prior to customer delivery. Three techniques are utilized to characterize system performance - simulation, stimulation, and performance measurement. Simulation involves writing a mathematical model which is enhanced from a product feasibility model to a system configuration tool as a result of stimulation and measurement activities. Stimulation consists of using emulators to load the system component under test as if the actual system is inter-connected. The emulators are programmed to produce a processing volume which can exceed the peak benchmark of the potential user. Performance measurement is accomplished during the stimulation activity using hardware/ software probes to monitor specific system parameters. These monitors provide vital information to determine total system capacity and the expected system performance for a given configuration. The information derived from system characterization is invaluable in providing the customer with a realistic expectation of system capability to perform its present functions and in projecting future growth potential.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
