Managing Large Multidimensional Datasets Inside a Database System
… in decision support applications, we develop an approximate query processing technique based on multidimensional wavelets. Our technique constructs compact synopses (comprising of wavelet coefficients) of the relevant database tables and subsequently answers any SQL query by working exclusively …

APPROXIMATE: A Query Processor That Produces Monotonically Improving Approximate Answers
… it may be better for a database to produce an approximate answer when it is not possible to produce an exact answer. We have designed and implemented a query processor, called APPROXIMATE, that makes approximate answers available if part of the database is unavailable or if there is not enough …

BUILDING EFFICIENT AND COST-EFFECTIVE CLOUD-BASED BIG DATA MANAGEMENT SYSTEMS
… networks and many others. Interactive querying and large-scale analytics are being increasingly used to derive value out of this big data. A large portion of this data is being stored and processed in the Cloud due the several advantages provided by the Cloud such as scalability, …
