Relationship: File Descriptor Has Property
In addition to creating and reading files, you can interpret and process the content of a file. File contents can also be linked with properties. This can be modeled using the File has Property relationship.
You can link file contents to properties only if the file has records with a defined structure, see the figure below.
| Attribute | Type | Description |
|---|---|---|
| TargetID * | Property | References a property whose value is part of the structured file. |
| Label [O] | String | Labels table column if the file should be displayed in a table. If no label is stated, the name is used as a label. |
| SeqNo * [U] | Integer | The sequence number of the property value in the structured file. |
| Visible | Boolean | Determines if this property should be displayed as a column in a table view.
The default value is true. |
| Editable | Boolean | Determines whether this table column is editable. |
The file (black dashed framed) contains several records with a defined structure (Element name, User-ID, Date). These values can be processed further using Relationships to Properties (red dashed framed).
Example
This file descriptor is used in an AWM tool of type "Open Modeled Dialog":
This means the file content is displayed in the form of a table within the dialog box.
| Attribute | Value | Description |
|---|---|---|
| Essential: | ||
| Seq No | 1 | This property is supplied in the first position of each row of the file descriptor. |
| Target ID | Reference to the property SCLM group. | The value on the first position of each row of the file descriptor is assigned to the SCLM group of the table entry. |
| Optional: | ||
| Editable | false | This table column is not editable. |
| Label | Group | The table header for this table column is 'Group'. |
| Visible | true | The corresponding column is visible in the dialog table. |
