Which part of Appian architecture handles CRUD operations on primary and business databases?

The correct answer is that the Application Server is responsible for handling CRUD operations on primary and business databases within Appian architecture. The Application Server plays a crucial role in facilitating communication between the user interface and the data storage components. It processes user requests, executes app logic, and interacts with the databases to perform Create, Read, Update, and Delete operations.

The Application Server acts as the intermediary that manages the application’s data flows, allowing users to manipulate and query business data effectively. It ensures that application developers can set up their applications to interact with various data sources seamlessly.

Other components like the Execution Engine, which handles the business logic and process execution, and the Analytics Engine, which collects and analyzes performance data, do not manage direct database interactions for CRUD operations. The Data Management Layer, while associated with data handling, is not typically referred to as the primary interface for executing these operations in conjunction with application architecture. Hence, the Application Server is the accurate answer as it specifically addresses CRUD operations in the context of the broader architecture of Appian.
