When configuring a Write to Data Store Entity smart service node to write a new row to a CDT ' s corresponding database table, you must specify the data store entity where the CDT is stored. Additionally, you need to provide an input of the type that matches the CDT, in this case, an input of type ACME_video, which will contain the data to be written to the database.

The most efficient method to access data for a pie chart in a child interface is to create a rule input on the child interface and pass the local variable data from the parent interface. This method avoids redundant data queries and takes advantage of Appian ' s pass-by-reference mechanism, which does not duplicate data in memory when passing it to the child interface.

Custom Data Type (CDT): Connect Appian to a relational database, establishing relationships between custom data types in Appian and corresponding tables in the database.

Process Model: Establish a data structure into which a process model can set values prior to writing to the database.

Constant: Store a reference to a group that will be assigned a task or receive a notification.

Custom Data Types (CDTs) define the structure of data within Appian and can be mapped to existing database tables to leverage relational database functionalities. They establish how data is structured and stored in the Appian application.

Process Models depict the workflow and logic of a business process. They can include user and automated tasks, and they can manipulate and store data before, during, and after the execution of the process.

Constants are reusable static values that can be referenced within Appian. They can store values like group references, which can then be used for task assignment or notification purposes in process models or other expressions.
