Abstract :
A novel database access method for statistical database processing is discussed. The structure of the access method and its application for the processing of statistical queries is shown. Descriptive statistics on attributes of the data can be calculated very efficiently. In addition, the structure is suited for queries involving order statistics on an index attribute. An extra advantage provided by the structure is the ability to do various kinds of sampling. The cost of processing various queries is analyzed. Structural updates to the access method are discussed
