| Abstract | Mutation testing involves systematically generating and introducing faults into an application to improve testing. A quasi-experimental study is reported comparing the fault-detection capabilities of real-world database application test suites to those of an SQL vendor test suite (NIST SQL) based on mutation scores. The higher the mutation score the more successful the test suite will be at detecting faults. The SQLMutation tool was used to generate query mutants from beginner-level sample schemas obtained from three popular real-world database test suite vendors -- MySQL, SQL Server, and Oracle. Four SQLMutation operators were applied to both real-world and NIST SQL vendor compliance test suites - SQL Clause (SC), Operator Replacement (OR), NULL (NL) and Identifier Replacement (IR). Two mutation operators, SC and NL generated significantly lower mutation scores in real-world test suites than for those in the vendor test suite. The IR operator generated significantly higher mutation scores in real-world test suites than for those in the vendor test suite. The OR operator produced roughly the same mutation scores in both the real-world and vendor test suites. |

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.
