Learn how to create flow level and data view variables in Mule 4 using transform message, with set variable, dynamic HTTP status, and payload handling for robust Mule flows.

Create local and global variables in DataWeave headers and access them in the body to map a COVID case payload for database insert, using an owner variable to avoid duplication.

Explore DataWeave type coercion using the as operator to convert strings to numbers and booleans, with practical examples on the postal code and is active fields.

Learn how DataWeave coerces strings to dates with as date, and how input formats are specified with the format keyword to yield correct year-month-day outputs.

Explore how the now() function retrieves the current system date and time in DataWeave. Learn to cast to date, time, or string with custom formats, handling time zones and milliseconds.

Design and implement real-time COVID case management APIs, including register, update, get by national ID, and get reports, with JSON and XML payloads and database mapping.
