Selective Querying (Zero-Overhead Data Filtering)

Under active development

Instead of creating dozens of custom API endpoints (as in REST) or deploying complex server-side query engines (as in GraphQL), DAXP supports Selective Querying natively on a single, universal entry point.

• How it works: The consumer sends a lightweight request containing only the specific numeric Tag IDs they need (e.g., $:108=2001;2002;2007). The universal backend processor (PL/SQL or Java) instantly reads this pattern and generates a response frame containing only those requested fields.
• The Benefit: No bandwidth is wasted transmitting bulky, unused nested objects. The client decides exactly what it needs, and the database engine doesn't spend CPU cycles fetching or formatting unnecessary data columns.
