See also: Cardinality. Omnidex uses bitmap indexes as an option for low cardinality data. Bitmap Indexes are used on read only data stores as they cannot be indexed online and can only be synchronized with data during a batch index operation. |

| - | Bitmap joins are characterized by having the "from" table and the "to" table as the same child, the purpose being to change which owner is current for the table. This step may be taken when joining between a parent and a child that are not already pre-joined. | + | |
