Hashing Methods and Relational Algebra Operations

Summary: Hashing-based relational-algebra algorithms for projection, equi-join, division, union, difference, and intersection; performance vs nested-loop and sort-merge on a monoprocessor with disks. Excludes selection and inequijoins; demonstrates hashing scalability for multiprocessor/multi-machine DBMS, with TECHRA in CAD, utility maps, and oil-field exploration.
