In the Oracle Data Platform, the "Supply Side" refers to foundational data elements that are passively

collected and structured to provide meaning within the data ecosystem. According to Oracle’s official

documentation, the supply side includes "Business rules" (A), which define the logic and policies

governing data usage, ensuring consistency and compliance, and "Domain objects" (B), which

represent structured entities or concepts within a business domain, forming the backbone of data

modeling. "Technical definitions of business terms" (C) pertain to metadata management, and

"Reports" (D) are outputs rather than core supply-side models. Oracle’s Data Platform Foundations

emphasize business rules and domain objects as key components of the supply side for data

integration and processing.
