DataSynth v2.0.0

Synthetic enterprise data generation for ML training, audit analytics, and system testing.

DataSynth generates statistically realistic, fully interconnected enterprise financial data. It produces coherent General Ledger journal entries, document flows, subledger records, banking transactions, process mining event logs, and graph exports across 20+ enterprise process families.

Generated data respects accounting identities (debits = credits, Assets = Liabilities + Equity), follows empirical distributions (Benford's Law, log-normal mixtures), and maintains referential integrity across 100+ output tables.

Quick Start

# Build from source
git clone https://github.com/mivertowski/SyntheticData.git
cd SyntheticData
cargo build --release

# Demo mode -- generates a complete dataset with defaults
./target/release/datasynth-data generate --demo --output ./demo-output

# Full audit simulation (113+ output files)
./target/release/datasynth-data generate --demo --preset audit-group --output ./audit-output

# Or configure for your use case
./target/release/datasynth-data init --industry manufacturing --complexity medium -o config.yaml
./target/release/datasynth-data validate --config config.yaml
./target/release/datasynth-data generate --config config.yaml --output ./output

Group Audit Simulation

The audit-group preset generates a complete enterprise group audit dataset following ISA, IFRS, US GAAP, and local regulations:

./target/release/datasynth-data generate --demo --preset audit-group --output ./audit-output

# Export in SAP, French (FEC), or German (GoBD) audit formats
./target/release/datasynth-data generate --config config.yaml --output ./output --export-format sap --export-format fec

This produces 113+ interconnected files:

| Category | Content | |----------|---------| | Financial Statements | Standalone + consolidated BS/IS/CF with elimination schedules | | Audit Lifecycle | Engagement, risk assessment, procedures, sampling, findings, opinion | | ISA 600 Group Audit | Component auditors, materiality allocation, scope, instructions, reports | | Risk Assessment | Combined Risk Assessment (CRA) per account area and assertion | | Audit Methodology | Materiality (ISA 320), sampling (ISA 530), analytical procedures (ISA 520) | | Accounting Standards | Deferred tax, ECL, provisions, pensions, stock comp, business combinations | | SOX Compliance | Section 302 certifications, Section 404 ICFR assessments | | Graph Export | 78+ entity types, 39+ edge types for ML training and AI agent interaction |

CRA drives sampling, sampling correlates with misstatement rates, misstatements drive findings, findings drive the audit opinion.

Key Capabilities

Statistical Foundations

Distribution engine -- Log-normal mixtures, Gaussian mixtures, Pareto, Weibull, Beta, and zero-inflated distributions with configurable components
Copula correlations -- Cross-field dependency modeling via Gaussian, Clayton, Gumbel, Frank, and Student-t copulas
Benford's Law -- First and second-digit compliance with configurable deviation for anomaly injection
Temporal patterns -- Month-end/quarter-end/year-end volume spikes, intraday segments, business day calendars (15 regions), processing lags, and fiscal calendar support
Regime changes -- Economic cycles, acquisition effects, and structural breaks in time series
Industry profiles -- Pre-configured distributions for Retail, Manufacturing, Financial Services, Healthcare, and Technology

Enterprise Process Simulation

Every process chain generates its own master data, documents, and journal entries -- all cross-referenced:
