SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides data teams in mapping fields between source and destination entities, enabling consistent data migration, ETL, and data integration across BeepDM workflows.

Core Features & Use Cases

  • Field Mapping: automatically map fields by name or customize mappings to match destination schema.
  • Entity Transformation: apply type conversions and transformation rules during data movement.
  • Mapping Persistence: save and reuse mappings across ETL workflows, with DefaultsManager integration to apply defaults where needed.
  • ETL Integration: seamless integration with ETL editors to generate import scripts from mappings.

Quick Start

Create a mapping between LegacyCustomers (LegacyDB) and Customers (MainDB), map fields by name, and save the mapping for reuse in ETL workflows.

FAQPage Schema
How do I map fields between source and destination entities for ETL?

Field mapping between source and destination entities is achieved by matching fields automatically by name or customizing individual mappings to align with the destination schema. This ensures consistent data transformation and movement during ETL operations.

Can I save and reuse entity mappings across ETL workflows?

Yes, mapping persistence allows you to save configured entity mappings for reuse across ETL workflows. DefaultsManager integration applies necessary default values, ensuring consistent data integration without remapping fields repeatedly.

How do I handle type conversions and transformations during data migration?

Entity transformation handles type conversions and transformation rules directly during data movement. This allows you to apply structural changes to the data as it flows from the source entity to the destination.

What is the best way to generate import scripts from existing entity mappings?

Generating import scripts from entity mappings is done through seamless integration with ETL editors. The MappingManager leverages your saved mappings within the editor to produce executable scripts for data migration.

How do I apply default values to destination fields when source data is missing?

DefaultsManager applies default values to destination fields where source data is missing or required. It integrates directly within the ETL editor to ensure consistent default value handling across persistent mappings.

Does BeepDM support mapping source to destination entities by structure instead of name?

Yes, BeepDM supports mapping source to destination entities by matching field names or by analyzing the underlying structure. This flexibility allows customization to fit specific destination schema requirements.
