When configuring a node to write a new video as a row in a CDT’s corresponding database table, which inputs must you configure?

• A. The data store entity and an input of type ACME_video
• B. A CDT type and a database connection
• C. The store data and a string input
• D. A data type and a numeric input

Answer: (A)

Writing a new row into a CDT-backed table requires two things: a data store entity and a value that matches the CDT structure. The data store entity specifies which table to write to and how to connect to the database, while the input must be a CDT instance (ACME_video) that carries the row data in the exact fields that map to the table’s columns. This combination ensures Appian knows where to persist the data and how to translate the CDT fields into the appropriate database columns. Without the data store entity, there’s no defined target table or connection for the write. Without a CDT-typed input, there isn’t a structured row with the correct field mappings to insert. A plain string or numeric input wouldn’t provide the full row structure or the necessary field-to-column mappings to perform the insert.
