Create a new file collector

Before starting this exercise, you will need to download train.zip. Extract the files to a convenient location on your local drive. Throughout the course, these will be referred to as the input files.

A file containing details of customer addresses can be found in the input files, at: 

[unzipped location]\inputData\AddressCheck\custAddrFiles\input\custAddr_20090322_1.txt

Open this file and have a look at the data in it. Notice, in particular, that there is a header line in the file with the column names of the data in the file.

You will now add a new file collector to your Introduction to Modelling analysis model to read this file into PhixFlow.

1. Hover your mouse over  Files in the toolbar to show the list of File options.
2. Drag  File Collector onto the model.
3. In the new file collector settings tab that opens, enter the Name: Customer Addresses.
4. Click  Apply and Close.

5. You will now see the new file collector on the model.

   In the toolbar, click  Save to make sure that the new file collector will be shown when you re-open this model. Remember to save the model layout every time you add a new modelling component.

Set up a file collector and table

1. Hover over your new file collector, and click  Upload File.
2. In the file explorer, go to: …\inputData\AddressCheck\custAddrFiles\input.
3. Select the file custAddr_20090322_1.txt and click Open.
4. In the Upload File window, click the Upload File button.
5. PhixFlow adds a new table to your model. PhixFlow has automatically configured the file collector and the table to load the file into PhixFlow.

Pause file data

In this course you will build up a model by adding components and running them. In PhixFlow, running a component causes each of its inputs to also run. This is so that you only need to run the final component in a model and it will, in turn, run everything you need to populate it, all the way back to the raw inputs to PhixFlow (via file collectors and database collectors).

In this case, once you have loaded the file, you will "pause" the file data so that you do not need to reload the file from your computer every time you run the model.
We will cover pausing components in PhixFlow in more detail in the Modelling Concepts course.
To pause the data loaded from the file:

1. In your model, hover your mouse pointer over the Customer Addresses Table icon.
2. In the popup toolbar, click Static.

Run analysis on the table

You will now run analysis on your new table. Analysis is the process that does all PhixFlow's data processing.
To run analysis:

1. In your model, hover your mouse pointer over the Customer Addresses Table.
2. In the popup toolbar, select the  Run Analysis. PhixFlow runs the model, reading in data from the file of customer addresses via the file collector.
3. You will get a confirmation message when this has completed. We will look at messages in the console later.

4. In the model window, click  Save.

View table data

To view the data you just loaded:

1. In your model, hover your mouse pointer over the Customer Addresses  Table.
2. In the popup toolbar, click  Show the list of Views.
3. The Customer Addresses (Default View) window will show like the image below:
