In this tab, you describe and define the structure of the
User Entities that will be created from the Meta Entity.
The tab is divided into two panes:
The Composition pane contains the elements
that will constitute the User Entities. You can add, remove, or move
elements by clicking the corresponding buttons. A User Entity can
be constituted of the following elements:
Data aggregate descriptions that are internal to the Meta Entity.
They are represented by the icon.
Data descriptions that are internal to the Meta Entity. They are
represented by the icon.
Existing Meta Data Aggregates. They are represented by the icons.
Existing Data Elements represented by the icon
in the Pacbase facet,
or existing Data represented by the icon in the COBOL facet.
The other pane contains sections (Component Usage for
example) where you enter the characteristics of the elements that
are inserted or selected in the Composition pane.
Data aggregate description in a Meta Entity (Type) or Meta Data Aggregate
You can add a data aggregate description in a Meta Entity,
Meta Entity Type, or Meta Data Aggregate. You must specify its characteristics
in the Data aggregate description and Component
usage sections. A data aggregate description can contain
other descriptions, existing Meta Data Aggregates, and existing Data
Elements (in the Pacbase facet)
or existing Data (in the COBOL facet).
Data description in a Meta Entity (Type) or Meta Data Aggregate
You can add a data description in a Meta Entity, Meta Entity
Type, or Meta Data Aggregate. You must indicate its characteristics
in the section that opens in the Composition tab.
Each description line corresponds to a data item (a field) that will
contain a value in the User Entity. For each data description, you
must indicate a format, values, and intervals.
Call of a Data Element (Data) or Meta Data Aggregate in a Meta Entity (Type) or Meta Data Aggregate
You can call instances that are already defined in the
repository. You can call Data Elements (in the Pacbase facet), Data (in
the COBOL facet), or Meta Data Aggregates in a Meta Entity, Meta Entity
Type or Meta Data Aggregate. You must indicate a cardinality and specify
whether the allowed values must be controlled for the Data Elements
or Data.
