An analysis model view shows a picture of an analysis model, or part of an analysis model.
Model views can include datasources, database collectors, database exporters, FTP sites, file collectors, file exporters, HTTP datasources, HTTP collectors, HTTP exporters and streams, which can be connected by pipes.
Model views can be saved, or built on request.
The model view details opens when you:

This page is for data modellers who are new to using PhixFlow. It provides an introduction to using the modelling window.
Opening a Model Window
PhixFlow opens a model window when you:
- add a new model. In the repository, right-click on Analysis Models and select
.Insert excerpt _add _add nopanel true - display an existing model. In the repository, double-click on an analysis model's name to open its properties. In the properties toolbar, click the

Model View Pane
The model view pane can be opened by right-clicking on an existing model in the repository browser and selecting Display.

- button to display its model window in the workspace.
The model window shows a picture of either all or part of an analysis model.
Model Properties
In addition to the Common Properties, analysis models have a Name; see Analysis Model. They do not have any other properties, as all their content is in the model itself.
Modelling Objects
The toolbar at the top of a model window includes icons for the different objects that you can add to the model. The types of modelling object are:
Drag an object from the toolbar into the model to add new object of this type. See For information about the list of object types under 2168684909.
Drag on existing objects
You can drag objects that have already been created onto a model view paneobject icons, see Modelling Window Toolbar Icons, below.
You can also drag in existing modelling objects from the repository. For example, if you want to include a stream, open the list of streams in the repository browser, select the stream and drag it onto the pane. Similarly, objects can be added from the list of datasources, file collectors, database collectors, file exporters, database exporters and FTP sites.
When you drag an object onto an model view in this way, if this it linked (via one or more pipes) to other objects on the view, PhixFlow will draw in the links.
If an object dragged onto a model view is not from the same application as the analysis model a small application icon will be visible on to add an existing stream:
- Open the repository → Streams branch and find the stream.
- Drag the stream into the model.
Objects in models must be connected by pipes. Hover your mouse pointer over an object to display the popup toolbar and add a

Usually you add modelling objects that belong to the same application. However, PhixFlow can share modelling objects between applications. When you drag in a modelling object from a different application, PhixFlow adds a small application icon to the top left of the object's icon.Anchor

Model Window Toolbar Icons
The default mode for the cursor in the model pane window is select. Pressing this button sets the mode to drag. Alternatively, while in select mode, keep the Ctrl key pressed on your keyboard, and with the left mouse button pressed move the pointer. | |
If you are in drag mode, pressing this button puts you back into select mode (the default mode when you open a new Analysis Model View panemodel window). While in select mode, keeping the left mouse button pressed and dragging over an area of the panewindow, you can select several items in the model. Press the Alt key on your keyboard to include Pipes in the selection. | |

Modelling Object Pop-up Toolbar
In the Analysis Model View pane a hover menu is also available for any object. To get this menu, move your pointer over the object and the hover menu will appear. The hover menu provides a number model, hover your mouse pointer over any object to display a pop-up toolbar. The pop-up toolbar some of the same buttons that appear in the menu bar, described above. It also provides the following buttons:
| Make this object static. | |
| Disable/ enable this object. |
Bring up a list of attributes for the object. Attributes can be selected from this list and dragged into an attribute list window for another object, so this is useful when building new objects in the model. | |
Show the list of views configured on this object. | |
Show the list of Stream Sets for this object. This brings up the Stream Set viewer. | |
Bring into the pane model all objects in the model that are inputs to this object. | |
Bring into the pane model all objects in the model that are outputs of this object. | |
Run the Analysis Engine analysis process on this object. All objects required to build the object selected will be run, but only these objects; so this may run Analysis . This means PhixFlow may:

Remove Erase this object from the Analysis Model View panemodel. This does not delete the object from the underlying model in PhixFlow. |

Window Context Menu
If you rightRight-click anywhere on the modelling pane a model window to display the context menu will appear.:
- Rollback Selected Objects: Rollback the data in the currently selected Streams
- Copy Selected Objects: Create copies of the currently selected objects
- Delete Selected Objects: Delete selected objects
- Enable Selected Objects: Enable selected objects
- Disable Selected Objects: Disable selected objects
- Switch The Static Flag On In The Selected Objects: Switch the 'static' flag on in the currently selected Streams and Pipes
- Switch The Static Flag Off In The Selected Objects: Switch the 'static' flag off in the currently selected Streams and Pipes
Moving a Model
...
If some objects are not visible on the Model Pane (i.e. are positioned outside the currently displayed area), arrows will be displayed. Arrows indicate that there are objects outside the display area and allow the user to quickly move the Model Pane and display those objects.
...
Window
As models get bigger, you may find that model window only shows part of the model. If part of the model is off-screen, PhixFlow will display arrows:
Use the arrows to move the model window to show different parts of the model. Alternatively, you can drag the model around in the model window.
Keyboard support
If you are in select mode 
, there are keyboard commands available:
- Ctrl: Switch
- either switch to drag mode (move the pointer with the left mouse button pressed)
- or select multiple items (click left mouse button on items).
- Alt: Include pipes in selection.
