Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process. The term flow diagram is used in theory and practice in different meanings. įlow diagrams are used to structure and order a complex system, or to reveal the underlying structure of the elements and their interaction. The term flow diagram is also used as a synonym for flowchart, and sometimes as a counterpart of the flowchart. Example of a flow diagram of a nuclear submarine propulsion system.įlow diagram is a collective term for a diagram representing a flow or set of dynamic relationships in a system. Right-click and select Add to Query, then Column."Boxes and arrows" redirects here. Multi-select the fields from the joined source that you want in the flow. Right-click the SQL object, and click Edit. Because of the inner join, these records will be excluded.Ĭlick the Close button (X) at the top right of the window to return to the data flow view. The excluded count, represent product numbers that were not found in one of the files. There was not a perfect match between the two files, as shown in the following image. The Join Profiler tab shows the effects of the join. Any row from both files that matches has the field values from both files, otherwise default values will be substituted. All rows from both files will be retained. If a row in the host file matches, its field values will be included in the row, otherwise default values will be substituted. All rows from the target file will be retained. If a row in the target file matches, its field values will be included in the row, otherwise default values will be substituted. All rows from the host file will be retained. The join fields in both sources must match, or the row will be excluded. You can edit the join condition, add additional join conditions, and change the type of join. You can also right-click the Join object and click Join Editor. The Join Configuration panel shows the join properties and enables you to edit them, as shown in the following image.Īn inner join was automatically created based on the same field name PROD_NUM in both files. The Join Editor and Sample Data panels open. To see the order information, you can drag the dmord synonym onto the flow canvas, as shown in the following image The dminv source has product data, but no order data. Alternatively, you can right-click the SQL object, click Add, then click Join or Union. If you drag it onto the canvas near the existing source, a join will be created, by default. You can add a join or union by dragging an additional source onto the existing source, as shown in the following image.ĭrag it to the Join bubble or Union bubble. For a union, select the matching fields in each source. In a union, all fields should match, and the union will add additional rows.If fields in both sources do not match the join conditions, rows may be excluded from the joined sources. The Join Editor lets you edit the join, selecting join type and join fields. ![]() In a join, shared fields or a condition in two sources will be used to add additional fields to rows.You can add multiple sources in a data flow as joins or unions. ![]()
