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 Modelling Window

PhixFlow opens a modelling 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 

  Insert excerpt
  _model _model nopanel true

   button to display its modelling window in the workspace.

The modelling window shows a picture of either all or part of an analysis model.

Modelling Objects

You can drag any object from the menu bar of a model view onto the modelling pane. This will create a new object of this type. See the list of object types under 2168684909.

Models are made up of modelling objects. They can include:

• data connectors, to load or export data
  • datasources
  • database collectors
  • database exporters
  • FTP sites
  • file collectors
  • file exporters
  • HTTP datasources
  • HTTP collectors
  • HTTP exporters
• the data is processed in streams
• objects are connected by pipes.

When you make changes to a model, remember to save your changes by clicking the

Add new objects

You can drag any object from the menu bar of a model view onto the modelling pane. This will create a new object of this type. See the list of object types under 2168684909.

Drag on existing objects

You can drag objects that have already been created onto a model view pane=. For example, if you want to include a stream, open the list of streams in the repository, select the stream and drag it onto the panemodel. Similarly, objects can be added from the list of datasources, file collectors, database collectors, file exporters, database exporters and FTP sites.

Modelling Window Toolbar Icons

	The default mode for the cursor in the model pane modelling 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 panemodelling 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.
	Organise selected objects in a grid.
	Align all selected objects left.
	Align all selected objects right.
	Align all selected objects to top.
	Align all selected objects to bottom.
	Distribute all selected objects horizontally.
	Distribute all selected objects vertically.
Object Types
	Add a new Datasource to the Analysis Model.
	Add a new FTP Site to the Analysis Model.
	Add a new HTTP Datasource to the Analysis Model.
	Add a new Database Collector to the Analysis Model.
	Add a new File Collector to the Analysis Model.
	Add a new HTTP Collector to the Analysis Model.
	Add a new Database Exporter to the Analysis Model.
	Add a new File Exporter to the Analysis Model.
	Add a new HTTP Exporter to the Analysis Model.
	Add a new Stream with function Aggregate to the Analysis Model.
	Add a new Stream with function Calculate to the Analysis Model.
	Add a new Stream with function Calculate By Set to the Analysis Model.
	Add a new Stream with function Cartesian to the Analysis Model.
	Add a new Stream with function Merge to the Analysis Model.
	Show model details

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 on this object. All objects required to build the object selected will be run, but only these objects; so this may run Analysis analysis on objects that are not in the panemodel, and Analysis analysis may not be run on some of the objects that are in the panemodel.
	Remove Erase this object from the Analysis Model View panemodel. This does not delete the object from the underlying model in PhixFlow.

Context Menu

Modelling Object Context Menu

Right-click on a modelling object to display its context menu. This includes many of the same options as in the menu bar or the hover menu. A few addition options are also available:

• Copy Object: Create a copy of the object
• Export Object: Export a copy of the object
• Show All Predecessors: bring all objects that are used to build this object in the underlying model into the panemodel.
• Show All Successors: bring all objects that use this object in the underlying model into the panemodel.
• Rollback Stream: rollback data in the Stream. This brings up the Rollback form.
• Permanently Delete: permanently delete the object from the underlying model in PhixFlow. This removes the object from PhixFlow completely - only do this if you are certain that you never want to use this object again.

...

Modelling Window Context Menu

If you rightRight-click anywhere on the modelling pane a 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 Model Pane

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.

Keyboard support

If you are in select mode, there are keyboard commands available:

• Ctrl: Switch to drag mode (move the pointer with the left mouse button pressed) / Select multiple items (click left mouse button on items).
• Alt: Include pipes in selection.
