Designing Process Logic (Flow Builder)
Welcome to the brain of the P4 Platform! We have our data tables ready, but they are completely empty and don't do anything yet. To make our Kanban Board work, we need to build the business rules.
In P4, we build these rules using the Flow Builder - a visual, drag-and-drop tool.
3 Core Concepts You Need to Know
Before we start connecting nodes, keep these three concepts in mind:
Nodes (The Steps): A Flow is made of visual blocks called "Nodes". Each node does one specific thing: loads data, creates a record, evaluates a condition (If), or calculates a variable.
The DataStore (The Virtual Memory): When a Flow runs, it operates entirely in the system's temporary memory called the DataStore. If a node creates or updates a record, it only happens in this virtual space first.
The End Node (The "Save" Button): Nothing is permanently saved to the real database until the Flow successfully reaches the End Node. If something fails in the middle of the process, the entire transaction is rolled back, keeping your data safe and consistent.
🛠️ What Processes Are We Building?
To make our Kanban Loop work, we need to break the logic down into three manageable flows:
