Synthetic data studio | Reveno Evidence

01 / Template Start from Rows

Seed

Paste a schema: SQL or JSON Table Schema

Paste a CREATE TABLE or a JSON Table Schema (Data Package). Types, NOT NULL, CHECK, enum, minimum and maximum become editor columns, and every assumption shows up as a warning. Structure only: do not paste data.

Schema

02 / Columns

Distributions: normal(mean, sd), lognormal(mu, sigma), uniforme(min, max), prob(p), categorias(a:30, b:70), sequencia(PREFIX), email, data(2025-01-01, 2025-12-31). The keywords are in Portuguese. Quasi-identifiers (QI) enter k-anonymity; sensitive attributes (S), l-diversity.

03 / Correlations

Between numeric columns, from -0.95 to 0.95. The generator uses a Gaussian copula; categories and booleans are independent.

04 / Cross-column rules

One per line. Order: data_entrega >= data_pedido, desconto <= valor (the left column is adjusted). Condition: if status = cancelado then motivo not null. Adjusting draws nothing: the seed still decides the dataset, and the Quality tab shows how many rows changed.

HOW TO READ THE REPORT

Three questions before using the file.

Formulas and limits in the method.

Is the file valid?

Types, bounds, categories, unique identifiers and null rate. It should be 100%.

Does it follow the specification?

KS for numeric columns, total variation for categories and expected versus obtained Spearman for correlations.

Does any record stand out?

Groups with fewer than 5 rows on the quasi-identifiers and rare categories call for a design review.

BRAZILIAN PUBLIC SOURCES

Official series to calibrate the synthetic data.

catalogo.json

11 series and tables downloaded unchanged from official APIs, with no key and SHA-256 checked on every publication. Latest collection: 2026-11-03 00:06:03 UTC. In the Studio they are a reference: generated rows remain synthetic.
