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.

1. In the model toolbar, drag the 
   Error rendering macro 'excerpt-include' : No link could be created for '_stream_merge'.
     onto your model.
2. In the settings, set Name: Customer All Details.
3. Click  OK to save and close the settings for the Customer All Details merge stream.
4. In the model, hover your mouse pointer over the CustomerAddresses stream.
5. In the pop-up toolbar, select  Connector , then click the end of the arrow onto the stream Customer All Details.
6. Similarly, add a pipe from the stream SOURCE_CUSTOMER_PHONE_NUMBERS to Customer All Details.
7. Double-click on the pipe from CustomerAddresses  to Customer All Details to open the pipe settings.

      1. Note that you can select all attributes by selecting the top attribute, pressing Shift and then selecting the bottom attribute
      2. When the dialogue appears, select Use original attribute name
   3. Similarly, drag all attributes from SOURCE_CUSTOMER_PHONE_NUMBERS to Customer All Details
   4. To see the resulting configuration in Customer All Details, double-click on this stream
      1. In the attributes section, you will see the added attributes
