Following the Flow: How Record Data Moves Through an Appian App



In our previous posts, we built out the data model for our fictional company, Acme Auto, using Appian Record Types. But a data model is only useful if users can actually interact with it! How exactly does data travel from a database table to a user's screen, into a form, and back again?

Let's trace the journey of a single vehicle record to see how data flows seamlessly through an Appian application.

1. From the Database to the Interface

The journey begins with your data resting safely in a database table. By configuring a record type, this underlying data becomes easily accessible throughout your entire Appian environment.

To actually display this information to an Acme Auto employee, the record type is used as a data type for a variable. This variable acts as a carrier, passing the vehicle data directly into a summary interface. When an employee opens this summary, they are greeted with a comprehensive view of the vehicle's information, along with its associated maintenance requests and user comments. Because the record type utilizes relationships, it automatically pulls in all of this related comment and maintenance data without needing complex queries.

Appian also provides records-powered components that make building these interfaces a breeze. For instance, the grid that displays a vehicle's maintenance requests simply uses the record type as its direct source. You can effortlessly use read-only grids, charts, and record pickers to populate your interfaces with record data.

2. Passing Data into a Process

Viewing data is great, but employees also need to take action. Let's say a mechanic needs to update a vehicle's condition and add a new comment.

When the user clicks the "update vehicle" button on the summary interface, the current vehicle data instantly enters a process. The data is passed directly into an Update Vehicle form, allowing the user to modify the existing information and type out their new comments.

3. Saving and Syncing the Changes

So, what happens when the user finishes their updates and clicks Save?

First, the user's updated information and new comments are passed further down the process model via a process variable. Next, the system takes that vehicle and related comment data and writes it directly back to the database tables.

Because Appian utilizes data sync, these changes are instantly synced across the platform. The moment the process finishes, the summary interface is updated, and the employee can immediately see the new condition and comment they just added.

The Takeaway By leveraging record types as variables, Appian allows you to seamlessly pass enterprise data from your database, into rich user interfaces, through complex process workflows, and safely back to your database again!
