2. Copyright 2007, Information Builders. Slide 2 JOIN, MATCH and MORE Basic Choices Employee Data Department Data Job Data Customer Data Invoices Product Data Support Data Purchase Orders Inventory Data When your report requires data from many different sources… …you need JOIN, MATCH or MORE to make the connections!

3. Copyright 2007, Information Builders. Slide 3 JOIN, MATCH and MORE JOIN - Basic Characteristics JOIN treats multiple structures as one Employee Data Department Data Job Data Customer Data Invoices Product Data Support Data Purchase Orders Inventory Data  Connects data sources based on fields or conditions  Creates a vertical concatenation  Excludes only comma, tab and token delimited files  Maximum 63 active JOINS  JOINed structure maximum 256 segments  JOINed record maximum 32K

4. Copyright 2007, Information Builders. Slide 4 JOIN, MATCH and MORE Basic Choices ? Equal fields or Conditions ? Real Fields or Virtual Fields ? One-to-One or One-to-Many ? Inner JOIN or Outer JOIN ? FOCUS Managed or Interface Managed Each JOIN relationship involves these choices:
