According to embodiments of the present invention, two or more attributes that are included in a plurality of attributes are aggregated into a group defined by a first data definition language syntax. The first data definition language syntax defines the group as having a groupID and one or more of an attribute definition defined in a comma-separated list and a group definition. The attribute definition is defined by a second data definition syntax. The first data definition language syntax includes the second data definition language syntax.
