ERD & Schema Drift Simulator

Witness multi-layer morphing and AST-driven schema drift ingestion in real-time.

Perspective Layers

Toggle between views. Witness how abstract entities compilation resolves FK auto-wiring in Logical, and exact types in Physical mode.

Universal Drift Pipeline

1

AST Extraction

Parses messy raw SQL statement into intermediate AST.

2

SchemaDriftEngine Diff

Compares current vs. desired node tree structure.

3

2-Pass SmartUpsert

Safely applies diffs, preserving Layout and visual coordinates.

Structured for Enterprise Integrity

NexSchema isolates layout coordinate data from your business structures, maintaining clean relational lineage across your entire catalog.

Hub-and-Spoke Registry

Isolates visual visual coordinates layout in CanvasNode while anchoring Conceptual, Logical, and Physical spokes back to unified Global Entity hubs. 1:N auto-wiring automatically injects Foreign Keys into target entity tables. M:N connection triggers instant Bridge/Intersection table resolution.

Dynamic Layout Isolation • Self-Wiring

Anti-Fragile Schema Drift Engine

A strict 3-phase reverse engineering pipeline. Raw DDL is processed via SqlAdapter Statement Parser to generate an AST parse tree. The SchemaDriftEngine diffs the structural change against the registered model state and executes a 2-pass transaction SmartUpsert, ensuring original IDs and coordinates remain untouched.

Fuzzy AST Extractor • 2-Pass Transaction

Horizontal Data Lineage Canvas

Trace horizontal data pipelines and transformations across models down to the column level. Bind tables and attributes using EntityLineage paths carrying custom SQL filter predicates (WHERE clauses), join statements, and advanced custom SQL data derivation expressions.

Column-Level Mapping • Filter Predicates

Enterprise Compliance & Governance

Secure your catalog with a database-backed taxonomy. Categorize properties with global compliance tags (PII, HIPAA, GDPR). Access safety guardrails prevent concurrent editing collisions via active canvas locks. All modifications and classification changes are registered in the immutable GovernanceAudit log.

Immutable Auditing • Collaborative Collision Lock
