Enterprise Join Semantics Architecture Suite SFS 24 + JFS 24
Unified Structural & Operational Standards for Relational Correctness Executive Summary The Enterprise Join Semantics Architecture Suite is a dual‑standard framework that defines the structural and operational laws governing relational joins. It establishes a complete, reproducible, and audit‑ready model for SQL correctness across analytical, operational, and ETL/ELT systems.
This suite unifies:
SFS‑24 — Structural Framework for Join Semantics
JFS‑24 — Join‑Filter Safety Standard
Unified Execution‑Phase Architecture
Collapse Theorem & Preservation Model
48‑Cell Semantic‑Structural Matrix
Governance, Diagrams, Mind Maps, and PDF Standards
Together, these documents form the first comprehensive architecture standard for join semantics and filter safety.
Purpose of the Suite Modern SQL engines silently collapse joins, eliminate NULL‑extended rows, and violate preservation guarantees without warning. These failures are not syntax errors — they are semantic failures.
This suite provides:
a structural model (SFS‑24)
an operational model (JFS‑24)
a unified architecture (SFS + JFS)
a collapse‑detection model
a governance and review model
a training and certification foundation
The result is a complete relational correctness standard suitable for enterprise adoption.
Core Standards SFS‑24 — Structural Framework for Join Semantics Defines the structural laws of joins:
preservation contracts
NULL‑propagation architecture
collapse boundaries
structural invariants
24‑cell structural matrix
semantic‑structural 48‑cell matrix

JFS‑24 — Join‑Filter Safety Standard Defines the operational laws of filters:
ON = matching
WHERE = elimination
safe vs unsafe filter placement
six collapse patterns
join‑filter safety matrix
operational doctrine (“WHERE kills NULLs”)

Unified Architecture The suite integrates SFS‑24 and JFS‑24 into a single architecture:
unified execution‑phase flow
collapse theorem
preservation model
governance‑centric view
48‑cell semantic‑structural matrix

Positioning Statement The Enterprise Join Semantics Architecture Suite is the first standards‑driven, academically grounded, enterprise‑ready framework that unifies structural and operational join semantics. It establishes a new benchmark for SQL correctness, governance, and architectural discipline.
