correct connection link to use for a logic diagram

Hello, I'm building a diagram that will representing web services pulling or pushing information to a system. I want to know from a readability standpoint should I use different areas to show the moving of data. Attached is the diagram.

For example in the diagram I have WMS application that uses a webservice to pull information from Alfresco. I represent that by showing an arrow coming out of Alfresco to the web service and the an arrow from the web service to WMS.

Is there a better to show this logic data flow?

Hi DFG,

One comment I had: the arrows connecting from the gray boxes to the Alfresco drum are not always clear--a viewer can't tell if the data flows one way or two ways.

You can add connection points to the Alfresco drum so that the connectors are separated:

1. Get the connection point tool (Home > Tools > Connection Point)
2. Select the Alfresco shape
3. Hold Ctrl and left-click new locations on the shape.

Now you can glue connectors to discrete points.

There might be some settings deep in the layout options that will separated these connectors, but it doesn't always work for me. Try:

1. Right-click a page tab and choose Page Setup...
2. Go to Layout and Routing tab
3. Experiment with the "Separate" and "Overlap" settings to see if connectors spread apart. This will probably work best if you glue connectors "to the shape" instead of to individual connection points, however.
