Dropping and linking components
Procedure
- Drop the following components from the Palette to the design workspace: a tPrejob, a tPostjob, two tFileDelete components, two tFileInputDelimited components, a tMap, three tFileOutputDelimited components, and a tBarChart.
- Connect the tPrejob component to one tFileDelete component using a Trigger > On Component Ok connection, and connect the tPostjob component to the other tFileDelete component using the same type of connection.
- Connect the first tFileInputDelimited to the tMap component using a Row > Main connection.
- Connect the tMap component to the first tFileOutputDelimited component using a Row > Main connection, and name the connection Population.
- Repeat the step above to connect the tMap component to the other two tFileOutputDelimited components using Row > Main connections, and name the connections Area and Density respectively.
- Connect the section tFileInputDelimited to the tBarChart component using a Row > Main connection.
- Connect the first tFileInputDelimited component to the second tFileInputDelimited component using a Trigger > On Subjob Ok connection.
- Relabel the components to best describe their functionality.
