DBridge: A Holistic Optimizer
DBridge is a tool to optimize database/web service access by performing optimizations that span across the boundaries of the application and the data source. This involves bringing together ideas from traditional database query optimization, program analysis and compiler optimization, in order to optimize database applications, bridging the gap between the query language and the programming language.
