Query processing and optimisation are critical components of modern database systems, serving to translate high‐level declarative queries into efficient, low‐level machine instructions.

Dynamic filtering is a technique that filters out unnecessary data in advance during the database query process. The core ...

Query processing and optimization are critical components of database management systems (DBMSs), as they directly influence the efficiency and performance of data retrieval operations.

On Monday the 19th of April 2021, M.Sc. Chao Zhang will defend his doctoral thesis on Performance Benchmarking and Query Optimization for Multi-Model Databases. The thesis is related to research done ...

By combining machine learning and adaptive query execution, query optimization in Presto could become smarter and more efficient over repeated use.

More importantly, the query optimizer should leverage in-memory parallel processing to perform post-processing operations that cannot be pushed down to the data sources.

This course covers advanced topics in database management systems, including query processing and optimization, indexing, transaction management, data warehousing, data mining, etc. It also covers ...
