| Abstract | Big Data deals with enormous volumes of complex and exponentially growing data sets from multiple sources. With rapid growth in technology, we are now able to generate immense amount of data in almost any field imaginable including physical, biological and biomedical sciences. With the diversity and amount of data in health care industry there is an increasing need to evaluate the components in big data frameworks and gauge their adaptability to analytics techniques. However, a key step in adapting big data tools is the portability of relational databases to big data environment. Since SQL is considered to be the de-facto language for interactive queries, in this paper, we evaluate the performance of SQL-like big data solutions for the portability of existing relational databases. Our work focuses on benchmarking multiple SQL-like big data technologies over Hadoop based distributed file system (HDFS) for Study Data Tabulation Model (SDTM) used in clinical trial databases for improving the efficiency of research in clinical trials. We use publically available clinical trial data (from National Institute on Drug Abuse (NIDA)), which follows SDTM, as a test bed to measure key parameters like usability, adaptability, modularity, robustness and efficiency of these solutions. With the intention to demonstrate how current clinical trial functionality can be replicated on a big data backend with high SQL-like functionality, we evaluate several types of ad-hoc SQL queries. |

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.
