A phase defines the period of time that data governed by a lifecycle will be retained by a particular tablespace.
You create phases on the Definition tab of a lifecycle using the Create Phase tool.
To view or edit a phase's properties, double-click its Browser or list entry. The property sheet tabs and fields listed here are those available by default, before any customization of the interface by you or an administrator. The General tab contains the following properties:
| Property | Description |
|---|---|
|
Name/Code/Comment |
Identify the object. The name should clearly convey the object's purpose to non-technical users, while the code, which is used for generating code or scripts, may be abbreviated, and should not normally include spaces. You can optionally add a comment to provide more detailed information about the object. By default the code is generated from the name by applying the naming conventions specified in the model options. To decouple name-code synchronization, click to release the = button to the right of the Code field. |
|
Stereotype |
Extends the semantics of the object. You can enter a stereotype directly in this field, or add stereotypes to the list by specifying them in an extension file. |
| Retention/Time unit | [age-based] Specifies the length of time that data will be retained in this phase. |
| Idle period/ Time unit | [access-based] Specifies the minimum length of time that the table must remain unaccessed before it is moved to the next phase. |
| Source | Specifies where the data to populate the phase is located. The default is the current (warehouse) database. For the first phase only in an age-based lifecycle, you can specify instead an external database (see Archiving Data From External Databases), in which case you must also specify a data source to link to the PDM that models the external database. |
| Tablespace | [Current database only] Specifies the tablespace with which the phase is associated. Select a tablespace from the list or click the tools to the right of this field to create a new tablespace or open the property sheet of the currently selected one. |
| Data Source | [External database only] Specifies the data source used to connect to the external database. Click the Create tool to the right of this field to launch the Data Source Wizard (see Linking an External Database via the Data Source Wizard) to create a data source and apply the appropriate tables to the lifecycle. |

Keywords |
Provide a way of loosely grouping objects through tagging. To enter multiple keywords, separate them with commas. |
