Retrieving the different ages and lowest age data

This scenario displays the number of occurrences of different ages and the lowest age in a group of customers. In this scenario, the customer data is entered manually.

You will see two ways to handle this data with the tMemorizeRows:

• Inside the same subJob (with the tJavaFlex).

• Outside the tMemorizeRows subJob (with the tJava).

This Job uses five components:

• tFixedFlowInput: it contains rows of customer data such as IDs, names, and ages of the customers.

• tSortRow: it sorts the rows according to the age data.

• tMemorizeRows: it temporarily memorizes a specific number of incoming data rows at any given time and indexes the memorized data rows.

• tJavaFlex: it compares the age values of the data memorized by the preceding component, counts the occurrences of different ages and displays these ages in the Run view.

• tJava: it displays the number of occurrences of different ages and the lowest age.

To replicate this scenario, proceed as follows:
