What's this about?
We use one running example: a customer database. Each step first states the requirement, then the implementation in Nuclos.
1. Install Nuclos
Requirement: Nuclos should be available on a machine for the customer database.
In Nuclos: Run the downloaded installer – see Installation (DE).
2. Configure the "Customer" business object
Requirement: The customer needs fields: customer number, name, key account (checkbox) and first contact (date).
In Nuclos: Create a new business object "Customer" with these attributes.
3. Design the input form
Requirement: Group the fields into a "Customer data" group in the layout.
In Nuclos: Create a layout record for "Customer" and design it in the WYSIWYG editor.
4. Define the workflow
Requirement: A customer moves through "under review" → "active" → "inactive".
In Nuclos: Enable the status model for "Customer" and model the states.
5. Add a "Contact type" field
Requirement: An extensible drop-down should record how the contact came about.
In Nuclos: Create a "Contact type" business object and reference it from the customer BO.
6. Maintain customer data
Requirement: New customers should be entered into the system.
In Nuclos: Open the customer form in the Rich or Web Client and enter data.
