Abstract
The data elements for a column of a table are fetched from irregular address locations in memory and stored as vector data with a regular address increment. Vector designating data is also generated which includes at least the first element address of the stored vector data and the increment of the vector. The vector data is processed by a program routine which can perform the processing required by a selected command and which includes vector instructions each designating at least one set of vector data elements to be executed, in such a manner that vector data elements are fetched successively from the data storage device and are supplied successively to a pipelined arithmetic or logical operation unit.
