NAME

       UR::DataSource::RDBMS::BitmapIndex - metadata about a data source's bitmap indexes

DESCRIPTION

       This class represents instances of bitmap indexes in a data source.  They are maintained by 'ur update
       classes' and stored in the namespace's MetaDB.

       The existence of bitmap indexes in a datasource affects SQL generation during a Context commit.  Oracle's
       implementation requires a table covered by a bitmap index to be locked while it is being updated.
