Dbms mcq questions and answers pdf5/25/2023 ![]() to investigate the morpho-structure of the buffalo CP microvasculature utilizing light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques, and 2. In the literature, the morphology of CPs and the process that regulates the production of CSF are virtually nonexistent for domestic ruminants. The choroid plexuses (CPs) in mammals produce the cerebrospinal fluid (CSF). The experiment results demonstrate both performance and scalability advantage of SQLMR compared to MySQL and two NoSQL data processing systems, Hive and HadoopDB. We also devise a number of optimization techniques to improve the performance of SQLMR. Existing SQL-based applications are compatible seamlessly with SQLMR and users can manage Tera to PataByte scale of data with SQL-like queries instead of writing MapReduce codes. SQLMR complies SQL-like queries to a sequence of MapReduce jobs. We develop a data management system for cloud, named SQLMR. ![]() In this paper, we propose a hybrid approach to fill the gap between SQL-based and MapReduce data processing. On the other hand, traditional SQL-based data processing is familiar to user but is limited in scalability. ![]() However, it has higher learning curve than SQL-like language and the codes are hard to maintain and reuse. MapReduce provides a framework for large data processing and is shown to be scalable and fault-tolerant on commondity machines. As the size of data set in cloud increases rapidly, how to process large amount of data efficiently has become a critical issue.
