NAME

OME::DataTable::Column - a column in a data table

Back to Top

DESCRIPTION

The DataTable interface describes the database tables used to store OME semantic types.

The actual mapping between semantic types and data tables occurs as a link between semantic type columns and data table columns. This link can be accessed via the AttributeType->data_columb method.
