This page guides you through the Sandbox Demo which is installed as an Application in the repository. The Quick Start takes about 30 minutes to complete. To access the demo, and follow these instructions from within PhixFlow:
- Run your PhixFlow installation. If necessary:
- Switch to Design Mode
- Expand the Applications branch.
- Expand the Help Viewer.
Developing an application in PhixFlow is a simple process:

Introduction
PhixFlow is a flexible platform that can help you to manage your data. This Quick Start Guide introduces the process you can follow for any project:
To illustrate the process, you will create a simple analysis model and build an application to view and update its data.
PhixFlow has a lot of different options and settings. So that you can work through the process, some things are already set up for you:
- the Excel spreadsheet which you can download from here
- styles, set as system/application defaults, so that PhixFlow knows how to format data tables - which we call grids
- a palette of application components that you can drag onto the layout.
- styles that control the colours and appearance of the screen
Understand Your Data
This needs to be shorter with a link to this:
Before you start any PhixFlow project, it is important to take time to understand your data.
- What is your data? Do you need to represent people, places, products, money, time? These are the data entities.
- How does the data connect? These connections are the data relationships.
- How will you represent the data in PhixFlow? This depends on the attributes the data has.
- Is the data "clean" or do you need to tidy it up?
- What data is missing? PhixFlow can combine existing data from different sources and use it to calculate additional data.
- What volume of data do you need to handle? For very large data volumes, you will be able to use modelling strategies to process data efficiently.
- What do you need to do with the data? What is the business problem you want to solve?
For this example, a sales team is using an Excel spreadsheet to manage a list of Business contacts. The data represents business customers (location, turnover) and people (names and addresses). The spreadsheet has the following tabs.
Businesses tab:
Contacts tab:
The data in the two tabs is connected by the the business name.
You want to make it accessible and maintainable by more than one person. You also want to add some simple CRM functions, so that you can add descriptions about the business.
Create an Application
The first step is to create a PhixFlow application. Everything you create will belong to this application.
- In the repository, right-click on Application and select Add.
- PhixFlow opens a properties tab for the application. Enter the name:
tbc
- Click Save.
- When prompted to load the application, say yes.
Add screenshot/video
Creation might create a menu
Model your data
You now need to load the spreadsheet that contains the data into your application.
- Open your application.
- Right-click Models and select Add. PhixFlow opens a properties tab for the model.
- In Basic Settings > Name enter:
Businesses
- In the toolbar for the tab, click Display.
- In the workspace on the left, PhixFlow opens an empty model.
- To load the Excel file, drag a File Collector from the model toolbar into the model.
- PhixFlow opens the properties for the file collector. Add a name:
Business-File
and Save the properties. - In the model, hover your mouse pointer over the file collector. PhixFlow displays a pop-up toolbar. Click Upload File . Browse to the Excel file.
- In the upload window, click the button. This process
- automatically configures the file collector properties to upload the file
- creates a stream ready to hold the data. Streams are like PhixFlow's internal spreadsheets.
Troubleshooting
Palette is blank
For file collectors, when you configure no properties, other than the name, when you upload the file PhixFlow automatically sets the other properties. If you make any changes to any field, even if you then delete the change, PhixFlow assumes you want to configure the properties yourself.
Setting Stream Properties
Have a look at the stream properties and Set
- Basic Settings → Period to Transactional
- Tick Audit Manual Changes
- Attributes → Description to Bigstring OK the attribute properties.
- Save the stream properties and pin the stream properties to keep them open.
Script
If you look in the stream properties, you can see PhixFlow had named the file using the file collector name. It already has the list of attributes - the table columns - from the first tab in the spreadsheet.
Key concept
At this point the stream knows about the data, but does not contain any data. This is the time to check that stream properties and the data types and sizes are correct. You cannot make changes to the attributes once data is loaded.
- Have a look at the stream properties. The Basic Settings → Period is set to variable. In general PhixFlow assumes you are processing large datasets in batches. We are going to be making individual changes to single data records (transactions) . So that PhixFlow optimises processing for this type of data, In the Period drop-down list, select Transactional.
- In the attributes, there is one data type that we want to change. Currently the Description is set to be a string with a maximum of 500 characters. To remove this restriction, we can change it to a "big string" which can have 4000 characters.
- As we are going to have multiple people making changes to the data, it will be useful to be able to see who made changes. To set PhixFlow to track this for you, tick Audit Manual Changes.
- In the Attributes grid, double-click on description. PhixFlow opens a Description tab for the attribute. in Basic Settings → Type drop-down, select Bigstring. Click OK to save and close the attribute description.
- Save your changes. Notice that the orange background tells you that the properties have unsaved changes. When you save, the backgound colour returns to light green.
- It will be useful to have the stream properties open later, so click the Pin icon.
Run Analysis
You model should now look like this
Hover our mouse pointer over the BusinessData stream and select Run Analysis
In the confirmation window, click Yes to confirm.
In the bottom left of the Screen, PhixFlow shows some confirmation messages. Close these.
We can now check that the data has loaded into the stream.
In the model, hover your mouse pointer over the stream and select Stream Views then select Default View. THis simply shows the data using a standard table view. You should see ...
You can now pull the data from the uploaded Excel file and into the stream. This is called "running analysis".
Hover your mouse pointer over the BusinessData stream

Script
Add attributes
Add the following attrinbutes:
BusinessUID as an Integer
BusinessName as a String of Size 100
Comment as a Big String
- Run the Stream
Create a view of the data (dashboard)
Create a new Dashboard to manage our data
Add the Businesses as a Grid to the dashboard
Split dashboard vertically
This is a place holder for the Comments
Split left area horizontally
Tick Maximised.
Name buisnesses
Opens a blank dashboard on left.
Drag stram from properites, and pick grid
Select UID to Description (not audit
Drop onto header bar
Dashboard shows the grid.
There are different ways to do this.
Split the dashboard horizontally and add a form
Set up CRUD Actions on a Form
Show all palletes
Application lego bricks - gui bits as palettes templates.
Drag purple form onto the dashboard pfApp Builder (inner) Business
Uses the template to add a form.
Note splitter is draggable to adjust the proportions and scroll bars added automatically.
What attributes do you want. In stream select attributes, select, shift-drag and drop. Adds attributes.
Description goes onto right
First Tab is for Business Details
Right click and create a new form
From the Theme 1 Template drag a “Form Inner” onto the display area
Drag the attributes from the Business Stream onto the left column
Drag Description onto the right side.
Change the header to Business details
Make the header "Dynamic" to use a the data from the attribute
Initially the form does not change whith selected
Drag UID onto form.
Creates a backgound filter to use the UID to decide which is selected. See properties and say yeas
Add a sort order. If you update without a sort order, updated data
Without audit it overrides the entry in situ. Audit - marks old record as invalid and makes a new stream set. Without sort order - moves to the bottom. Sort by name, uid - use the dasboard.
LOcking and unlocking the layout
