- Files
  You add a file to a project to use it as input in the project. You can upload a file from your local file system to a project from the Files tab to generate test data. Alternatively, you can upload it when you define an action.
- Connections
  A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.
- Schema design
  A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.
  - Introduction to schema design
    Use the Schemas tab to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - Type properties
    The properties of a type define the characteristics of the data objects of that type.
  - Item restrictions
    Item restrictions are an optional feature you can use to specify valid or invalid data objects for an item type. Item restrictions are grouped into three categories: Value, Character, and Range.

Benefits of partitioning

Using the previous example, explore the benefits of partitioning.

The rule with partitioning is shorter than the rule without partitioning. The knowledge of which states belong to each region is maintained in the type tree rather than the rule.
It is easy to read this rule and understand the mapping function being performed. For example, if the state belongs to the list of states in the eastern region, execute the MapEast functional map.
The partitioning method is easier to maintain. If a value for State is added or moves from one region to another, it can be easily changed in the schema and automatically reflected in any rules that reference the partitioned object.
Partitioning using a restriction list used with the Ignore Case setting eliminates the need for PROPER, LOWERCASE, or UPPERCASE functions to compare each state with a literal.
