报告内容摘要：

This paper presents a technique called WideTable that aims to improve the speed ofanalytical data processing systems. A WideTable is built by denormalizing thedatabase, and then converting complex queries into simple scans on theunderlying (wide) table. To avoid the pitfalls associated with denormalization,e.g. space overheads, WideTable uses a combination of techniques includingdictionary encoding and columnar storage.
