--- title: Create a Mart Composite description: A Model Object of type Mart Composite can be created in the Datamart Layer. What is a Mart Composite A Mart Composite is a free-style data mart modeling that should provide a particular perspective on top of a data vault, a dimensional or a relational model for front-end tools (like views for multidimensional cubes). --- [Skip to content](https://knowledge.bigenius-x.com/create-a-mart-composite#main-content) [Contact us](https://knowledge.bigenius-x.com/kb-tickets/new?hsLang=en) [Go to Customer Portal](https://knowledge.bigenius-x.com/customer-portal?hsLang=en) [![TRI\_Logo\_biGENIUS\_2020\_RGB\_s](https://knowledge.bigenius-x.com/hs-fs/hubfs/Marketing/TRI_Logo_biGENIUS_2020_RGB_s.png?width=150&height=42&name=TRI_Logo_biGENIUS_2020_RGB_s.png)](https://www.bigenius-x.com/) Open main navigation Close main navigation - [Contact us](https://knowledge.bigenius-x.com/kb-tickets/new) - [Go to Customer Portal](https://knowledge.bigenius-x.com/customer-portal) How can we help you? - There are no suggestions because the search field is empty. 1.

[Model Object Type](https://knowledge.bigenius-x.com/generators?hsLang=en#model-object-type) # Create a Mart Composite A **Model Object** of type ***Mart Composite*** can be created in the **Datamart** Layer. ### What is a Mart Composite A **Mart Composite** is a **free-style data mart modeling** that should provide a particular perspective on top of a data vault, a dimensional or a relational model for front-end tools (like views for multidimensional cubes). It represents an **intermediate object** which can be used in a Mart Dimension or a Mart Fact in case of complex or standard calculations to use in several Model Objects. ### Creation steps There are two possibilities to create a ***MartComposite* Model Object**: - [Create a Model Object with the Wizard](https://knowledge.bigenius-x.com/create-a-model-object-with-the-wizard?hsLang=en): - **Recommended** possibility - Use the Wizard **Create a Mart Composite from a Raw Vault or a Business Vault Composite** that contains the following steps: -
