Re: Against the Grain: Pascal commentary about XML and databases
<< RDBMS systems have evolved and gobbled up much of the research on data warehousing to include those techniques into the engines -- witness materialized views and bitmapped indexes. Someone reading this might assume the bitmapped index is a byproduct of data warehousing, or possibly that bitmapped indexing is built on a relational foundation. That's not the case. The bitmapped index search pre-dates the relational model and data warehousing. Computer Sciences' had a hierarchical DBMS in the '60s that used bitmapped indexes. TRW's GIM DBMS at NASA MFC was updated with bitmapped indexing in the early '70s. Bitmapped index technology can be applied on top of a hierarchical data model.
