# Data model

Atoti Market Data has a simplified data model, split by the number of axes of the market data.

All retrieval configuration classes (providing store and retriever Spring Beans) can be found in the `com.activeviam.config.retrievers` package of the `market-data-config` module. For using all the market data stores and their associated retrievers at once, please use the provided Spring Boot Starter.

## Cube market data

Market data defined along three axes (tenors, moneyness, and underlying maturities). The store and retriever are defined in `CubeMarketDataRetrievalConfig`.

## Curve market data

Market data defined along a single tenor axis (e.g. UK CPI). The store and retriever are defined in `CurveMarketDataRetrievalConfig`.

## FX rate market data

Market data for FX rates. The store and retriever are defined in `FxRateMarketDataRetrievalConfig`.

## Spot market data

Market data defined as a single value per instrument (e.g. spot prices). The store and retriever are defined in `SpotMarketDataRetrievalConfig`.

## Surface market data

Market data defined along two axes (tenors and moneyness). The store and retriever are defined in `SurfaceMarketDataRetrievalConfig`.
