Forms: Analysis Model View

An Analysis Model View shows a picture of an Analysis Model, or part of an Analysis Model.

Analysis Model Views can include Datasources, Database Collector, File Collector, Streams, Alarm Generators, Database Exporters, File Exporters and FTP Sites.

Models can be saved, or built on request.

Note that all objects that appear on Analysis Models have a context menu entry "Show Models" which will display a list of all the models that contain that object.

Form: Analysis Model Details

The Analysis Model Details appears when you press Image Removed from the list of Analysis Models, to create a new Analysis Model. These details can also be requested for an existing model from the Analysis Model View pane - see below.

Form Icons

The form provides the standard form icons.

Form: Analysis Model View Pane

Models on request

Analysis Model Views can be created on request from any of the elements that can be shown in a model pane. For example, if you want to create an Analysis model view for a Stream, open the list of Streams, select the Stream, right click and select Show Model Predecessors. A new Analysis Model View pane will be generated with the Stream selected, and all its predecessors - that is, the Collectors, Streams, Alarm Generators and Exporters that must be run to generate this stream.

Drag on existing objects

You can drag objects that have already been created onto an Analysis Model View pane. For example, if you want to include a Stream, open the list of Streams, select the Stream and drag it onto the pane. Similarly, objects can be added from the list of Datasources, File Collectors, Database Collectors, Alarm Generators, File Exporters, Database Exporters and FTP Sites.

When you drag an object onto an Analysis 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.

Form Icons

The form provides the standard form icons as well as the following:

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 

  Insert excerpt
  _model_display _model_display nopanel true

   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:

• data connectors, to load or export data
  • Datasource
  • Database Collector
  • Database Exporter
  • FTP Site
  • File Collector
  • File Exporter
  • HTTP Datasource
  • HTTP Collector
  • HTTP Exporter
• Stream to process the data
• Pipe to connect the objects

Drag an object from the toolbar into the model to add new object of this type. For information about the object icons, see Modelling Window Toolbar Icons, below.

You can also drag in existing modelling objects from the repository. For example, to add an existing stream:

1. Open the repository → Streams branch and find the stream.
2. 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.

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

Modelling Object Pop-up Toolbar

In the 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:

Image Added	Make this object static.

Modelling Object Context Menu

If you right Right-click on any object in the Analysis Model View pane a context menu will appear. Many of the options available are the same as those available from the menu bar or a hover menu, as described above. A few a modelling object to display its context menu.

Window Context Menu

If you right Right-click anywhere on the modelling pane a the model window to display the context menu will appear.:

• Rollback Selected Objects: Rollback the data in the currently selected Streams and Alarm Generators.
• Copy Selected Objects: Create copies of the currently selected objects.Export Selected Objects: Export 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 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 Image Added, there are keyboard commands available:

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