When you design your fulfillment solution, you need to develop a model comprised of data for use in multiple applications. For example, you may want to create order templates, atomic actions, and service specifications, and share the data defined for those entities across your OSM, ASAP, and Inventory applications.To facilitate this data sharing across products, Design Studio includes the concept of the Data Dictionary.
The Data Dictionary is a logical repository of data elements and data types in a workspace. Data types can be contributed from entities in the workspace, such as Activation service actions. The data elements are created and saved in data schemas, which can be accessible across all projects in a workspace. Design Studio automatically creates a project-specific data schema when you create a cartridge project. You can use this default schema to contain the data you require to model the project, you can create multiple schemas in the same project, or you can create schemas in common projects. You can model your cartridge project using data from any combination of these data schemas.
