Dataphin:Step 5: Build a data model

Background information

Data modeling uses visual representations to define business processes, helping you understand and improve business operations while eliminating information silos and data discrepancies. Dataphin applies the OneModel methodology, which organizes data modeling into four layers:

• Subject area modeling: A subject represents a macro analysis domain, such as "sales" for sales analysis. A subject area groups related subjects, and each industry typically has around 10 subject areas.

• Conceptual modeling: Defines entities and their relationships within each subject area.

• Logical modeling: Adds attributes and constraints to each entity based on the conceptual model.

• Business analysis modeling: Identifies key analysis methods and perspectives. Derived metrics and business filters are refined from the logical model to address specific analysis needs in Dataphin.

Step 1: Create a subject area

1. On the Dataphin home page, single click Planning in the top menu bar.

2. Follow the operation guide below, select the dataphin_tutorial data unit, and navigate to the Create Subject Area page.

   

3. On the Create Subject Area page, enter the required parameters.

   Parameter	Description
   Subject Area Name	Enter Transaction Domain.
   Code	Enter trade.
   Abbreviation	Enter trade.
   Parent Subject Area	Leave as empty.
   Description	Provide a brief description, such as Transaction Domain.

4. Click OK to confirm.

Step 2: Create a business object

1. On the Data Architecture page, use the operation guide below to access the Create Business Entity dialog box.

2. In the Create Business Entity dialog box, set the parameters as follows.

   The following example creates a Product business entity:
