Scalable Web Services Interface for SD-SQL Server

SD-SQL Server is a scalable distributed database system. Its original feature is dynamic and transparent repartitioning of growing tables. It avoids the cumbersome manual repartitioning necessary with current technology. SD-SQL Server re-partitions a (distributed) table when an insert overflows existing segments. To its user, SD_SQL offers the comfort of a single node, while allowing the larger tables and faster response time made possible by dynamic parallelism. We present the architecture of our system and its command interface. We present the Extended Web Services (EWS) Interface we have recently added to SD-SQL Server. We study the relative EWS query speed. It remains insufficient for larger data sets to be retrieved
