Working Space

Working space consists of a panel of components, toolbar and area of the Workflow construction (refer to Figure 1).

The panel of components is located on the left. It consists of the following categories:

• Components are represented by a standard library of the Megaladata base components.
• Derived components are the components created by users according to the base ones.
• Connections are data sources.

The Workflow construction area is located in the centre: the area containing the Worlflow nodes and links between them.

The toolbar that enables the following operations with the construction area and its constituents is located in the upper part:

• Show/Hide component panel enables to open or hide the panel of components.
• Object selection mode: the mode used for the Workflow construction by means of standard manipulations.
• Workflow navigation mode: the mode used for navigation in the Workflow construction area by means of a mouse.
• Show as workflow enables to display a Workflow in the standard form (in the form of oriented graph).
• Show as table provides compact display of the Workflow in the form of a table that contains used items.
• Vertical alignment provides vertical alignment of the Workflow nodes in the construction area. There are the following types of the vertical alignment:
  • Align left
  • Align middle
  • Align right
  • Align top
  • Align center
  • Align bottom
• Auto node alignment: the automatic placement of nodes in the Workflow area according to their sequence of data processing.
• Send selected nodes enables to bring selected nodes and their signatures to:
  • Front
  • Back
• Customize execution order enables to set one's own order of nodes execution.
• Run all enables to run all nodes of the Workflow.
• Activate/ Deactivate node enables to activate/deactivate a node.
• Retrain node enables to retrain the selected node.
• Configure node provides access to setting of the selected node.
• Configure node activation mode provides configuration of activation mode for the selected node.
• Clone node enables to clone the selected node.
• Expand/collapse supernode enables to collapse the selected nodes into the Supernode, or expand the selected Supernode into compound nodes.
• Delete selected enables to delete the selected nodes/links of the Workflow.
• Create derived component enables to create the Derived Component based on the selected node.
• Show parent nodes for derived shows parent nodes if derived nodes are available.
• Show source nodes for Reference Nodes shows the nodes on the basis of which Reference Nodes were created, if any.
• Show workflow outline enables to open for the navigation purposes a reduced copy of the Workflow construction area suitable for scaling.
• Show/hide property inspector enables to expand/collapse the Property inspector window. This button is always located in the far right position on the toolbar.

Note: When the Property inspector window is opened, there can be not enough place for some buttons on the toolbar. In this case, button with a drop-down list appears on the toolbar. It will contain all other buttons for which there is no enough place on the toolbar.
