Defining Categorization Schemas
Several categorization schemas can be proposed:
Data categories 
HOPEX IT Architecture Solution enables data classification using data categories.
*For more information on Data Categories see the HOPEX Data Governance guide.
To access the list of data categories using the Administration navigation pane:
*Select Categorization Schemas and unfold the Data Categories.
The list of the repository data categories appears.
To create a data category from the Administration navigation pane:
1. Select Categorization Schemas.
2. Select the Data Categories folder and click the New > Data Category button .
3. Enter the Name of your data category well as its Owner and click OK.
The new data category appears in the list.
To connect an data to a data category::
1. Open the Entities property page.
2. Select the tab that corresponds to the data you want to classify.
3. Click the Connect button ans select the data that interests you.
KPI Categorization Schemas 
The KPI Categorization Schemas allow you to define measurement systems specific to the area you want to deal with.
For example: the “Retail bank” schema or the “investment bank” schema.
A KPI Categorization Schema is a set of KPI Categories.
For example: “Security” or “Performances” are KPI Categories
A KPI Category is defined by several characteristics:
• Flow measure types, which are defined by a set of Flow measures.
• Technical flow measure types, which are defined by a set of Technical flow measures.
• KPI categories.
Measure flows 
Measure flows provide a way to define parameters of the application flows that are used described in the scenario of flows.
*An application flow represents the circulation of information between applications or within an application. An application flow can carry a content.
*For more details on scenario of flows, see Using a Scenario of Application Flows Diagram.
To access the list of Measure flows using the Administration navigation pane:
*Select KPI Categorization Schemas and unfold the HOPEX Measure Scheme.
The displayed tree enables the access to existing Measure flows.
