This technical note introduces the fundamentals of 4D AIKit, explains how to configure and use it, and demonstrates its practical value through an integrated business-oriented demo. The example shows how text, image, and conversational features can be combined to create practical AI-powered solutions.
This technical note leverages the 4D.SystemWorker class to enable non-blocking shell executions for generating Private Keys, Certificate Signing Requests (CSR), and self-signed certificates.
4D 21 introduces a new way to handle database operations using ORDA events. This approach replaces traditional triggers and offers better control over data operations. ORDA events run automatically when data is created, modified, saved, or deleted, allowing developers to add validation, error handling, and business logic directly in their code.
