Description

Table for an Observation is defined by the associated DataItem::representation as TABLE.

DataItem::representation as TABLE MUST have DataItem::category as SAMPLE or EVENT.

Figure WorkOffsetTable shows the model for WorkOffset (Event type) with a Representation type of Table.

Note: See Section Representation Schema Diagrams for XML schema.

Table has the same behavior as the DataSet for change tracking, clearing, and history. When an Entry changes, all Cell entities update at the same time; they are not tracked separately like Entry.

The meaning of each Entry and Cell MAY be provided as the DataItem EntryDefinition and CellDefinition.

Entry::key MUST be the unique identity of the Entry within an Observation. Cell::key MUST be the unique identity of the Cell within an Entry.

Figure Table Example shows Event Observation type WorkOffset with a Representation type of Table.

Note: See table-example for the XML representation of the same example.
