Multi Table Synthesizers

The SDV offers a variety of synthesizers, which use different algorithms to generate synthetic data. This section describes multi-table synthesizers, which are able to model interconnected, multi-table datasets.

＊Day Z Synthesizer

Generate synthetic data from scratch using only the metadata. This synthesizer produces multi table data with the correct formatting and referential integrity.

＊ Independent Synthesizer

Use various ML algorithms to model each table independently. This synthesizer offers the fastest performance for unlimited tables.

HMA Synthesizer

Use a hierarchical ML algorithm to learn from real data and generate synthetic data. Produce data for limited columns in up to 5 tables with a depth of 1.

＊HSA Synthesizer

Use a segment-based ML algorithm to learn from real data and generate synthetic data. This synthesizer offers fast performance for unlimited tables.
