# Glossary

Words and Expressions commonly used in the Valsight Application.

Assumption

Assumption

An Assumption bundles multiple *Assumptions Line-Items* to collect all changes for a financial concept, such as an Assumption, Option, or Measure.

**Assumption Line-Item**

Assumption Line-Items describe a change to the base data of a model and affects exactly one node. Changes are always non-destructive so that the original data remains intact.

**Baseline**

The baseline is a special scenario that is the basis of all simulation scenarios and is not impacted by simulations.

**Calculated Node**

Calculated nodes (default color blue) are always calculated from other nodes using an operation that allows to combine nodes with simple mathematical operations or more advanced node operation functions. Starting with version 1.19 they can also use data via the data function directly.

**Data Node**

Data nodes (orange) connect the model to a data source and define the data and its dimensionality. They are not longer used in new models, as all functionality can be achieved with the DATA function and Calculation Nodes.

**Data Source**

A data source can be an external relational database with multiple database tables or an internal list of data tables that were entered manually or uploaded.

**Inspector**

The inspector is a panel on the right side of the screen, that is used to configure objects in the application. It can be collapsed and expanded by pressing 'i'. The panel is context sensitive and always shows and changes the properties of the selected object.

**Model**

Value driver models define the calculation logic of a project using multi-dimensional operations and connect it with data sources.

**Node**

A node is the smallest element of a value driver model and the entity used to define the calculation logic using operations. Nodes can be of different types like data nodes or calculated nodes.

**Simulation**

Simulations are a powerful approach to calculate different scenarios based on a list of assumptions that alter the original data and are always calculated using the model logic so that all results are consistent and available in all dimensions.

**Simulation Scenario**

A simulation scenario groups a set of assumptions that describe how alternative actions impact nodes in the value driver model.

**Simulation Workspace**

A simulation workspace is a sandbox that allows to create simulation scenarios and to visualize, analyze and compare them using charts and tables.

**Global Workspace Filter**

A global workspace filter restricts the view of data in a workspace so that only the selected values can be viewed in charts or changed in simulations. The filter is applied to all charts in all tabs of a workspace.
