What does the data model define in relation to the BDC Component?

The data model is crucial in defining the structure of the data within the BDC (Business Data Connectivity) Component. It outlines how data is organized, including the relationships between different data entities and the specific data types used. This comprehensive definition lays the groundwork for not only understanding how data can be stored and accessed but also provides opportunities for extension and customization, as new attributes or entities can be added as business needs evolve. Additionally, the data model encompasses considerations regarding authorization, ensuring that access to data adheres to security protocols and user permissions.

This holistic view is essential for developers, as it informs how they can build upon existing structures while maintaining data integrity and security. Hence, the data model's definition regarding structure, extension, and authorization is fundamental in leveraging the full capabilities of the BDC Component effectively.
