SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides authoritative guidance on designing and implementing PIT and Bridge tables in a Data Vault environment (DVOS). It clarifies when to use legacy PIT vs SNOPIT, how to declare and materialize PITs and Bridges in manifests, and how to apply naming rules and guards to maintain correct historical data queries.

Core Features & Use Cases

  • PIT types and decision guidance: legacy PIT vs SNOPIT, including dv_sid enable_dv_sid requirement.
  • Bridge types: relationship, current_relationship, and fact bridges, with example manifest declarations and patterns.
  • Materialisation options and governance: dynamic_table vs ctas, ghost records, as_of calendar, multi-table inserts, and safety rules around clustering and dv_sid usage.

Quick Start

Define your PITs and Bridges in a DVOS manifest using pits and bridges blocks, then deploy with your chosen materialisation settings.

Frequently Asked Questions about dv-pit-bridge

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the difference between legacy PIT and SNOPIT structures in a Data Vault?▼

Legacy PIT and SNOPIT are Point-in-Time table structures used in Data Vault environments. SNOPIT requires enabling dv_sid, while the choice between them depends on specific query optimization needs and historical data tracking requirements.

How do I configure PIT and Bridge tables in a Data Vault manifest?▼

Configure PIT and Bridge tables in a DVOS manifest using pits and bridges blocks. Specify pit_type, materialization settings, tenant filters, and naming rules across hubs and links to shape scalable, maintainable vaults.

When should I use dynamic_table vs ctas materialization for Data Vault PITs?▼

Use dynamic_table or ctas materialization for Data Vault PITs based on governance and safety needs. Dynamic tables offer continuous refresh, while ctas provides reproducible builds, with both supporting ghost records and as_of calendar configurations.

What are the safety rules for clustering and dv_sid handling in Data Vault PITs?▼

Data Vault PIT safety rules require avoiding unsafe clustering, preventing ghost-record issues, and ensuring correct DV_SID handling. These guards maintain proper historical data queries and enable reproducible builds across hubs and links.

What types of Bridge tables can I use in a Data Vault environment?▼

Bridge tables in a Data Vault environment include relationship, current_relationship, and fact bridges. Each type has specific manifest declaration patterns for connecting hubs and links to optimize Information Mart query performance.

Do I need tenant filters and as_of calendar settings for Data Vault PITs?▼

Tenant filters and as_of calendar settings are required configurations for Data Vault PITs. They ensure proper historical data queries, support multi-table inserts, and maintain governance across materialized PIT and Bridge structures.
