	Generates a synthetic catalog with default options.

Detailed Description

Service for generating coherent synthetic data catalogs.

This is the main entry point for the ores.synthetic library. It creates complete synthetic data catalogs with proper relationships between entities. All generated data is consistent, high-quality, and can be used together for testing purposes.

Key features:

• Reproducible generation with configurable seed
• Proper entity relationships (datasets reference catalogs, dimensions, etc.)
• Realistic data values for financial/data management domains
• Configurable counts for all entity types

Example usage:

catalog_generator_service service;
 
// Generate with defaults
auto catalog = service.generate();
 
// Generate with custom options
generation_options opts;
opts.seed = 42;  // Reproducible
opts.dataset_count = 50;
auto catalog2 = service.generate(opts);
 
// Regenerate same data
opts.seed = catalog.seed;
auto same_catalog = service.generate(opts);

Member Function Documentation

generate() [1/2]

domain::synthetic_catalog generate

(

const domain::generation_options &

options

)

Generates a complete synthetic data catalog.

Creates a coherent catalog where all entities reference each other properly. Datasets reference existing catalogs, domains, dimensions, and methodologies. All recorded_by fields reference existing accounts.

Parameters

options

Configuration for the generation process.

Returns

A complete synthetic catalog with proper relationships.

generate() [2/2]

domain::synthetic_catalog generate

(

)

Generates a synthetic catalog with default options.

Uses sensible defaults for all entity counts:

• 5 accounts
• 3 catalogs
• 4 data domains with 3 subject areas each
• Standard dimension values
• 5 methodologies
• 20 datasets

Returns

A complete synthetic catalog with default sizes.
