By the end of this chapter you will be able to:

• Create merge streams
• Configure groupings on pipes

In this exercise, you will merge the two sets of data you just loaded into PhixFlow: the data from the file, and the data from the database.

• In the model, select the stream CustomerAddresses
• Then select the Stream SOURCE_CUSTOMER_PHONE_NUMBERS – keep your ctrl key pressed down, and select the Stream with your left mouse button
• Right-click anywhere on the background pane of the model (but not on either of the Streams you have just selected)
• Select Merge Selected Streams
• When the Stream Details form pops up, enter the Name: Customer All Details
• A form will appear – in this form, you can select the key fields that you will use to join the data across the two sources:
  • In the box with title in press
  • Drag the attribute CustomerRef into the box
  • Close the list of attributes
  • In the box with title in_2 press
  • Drag the attribute CUSTOMER_REF into the box
  • Close the list of attributes
  • Press 
  • An Automatic Stream Configuration form will appear – accept the default in the drop-down list (All Attributes) and press 

A new merge Stream will appear on your model - Customer All Details.
