Overview

To create a simple Data Structure (DSD) from scratch you need to consider the following elements as shown in the diagram below:


DSD Components

This article will show you how to create a simple DSD but first there are the preparation steps as outlined below.

Agency

You can either use an existing Agency or create a new one. In this guide we will assume that a new is created with the ID of MY_AGENCY.

Codelists

Codelists are used to define the allowable values in the DSD.

Codelists can be created from scratch or perhaps you already have suitable Codelists in your Registry? Be sure to check that the Codelists you need are available before you move to the next step.

You can watch how to do this in this video.

The video also shows you how to load exiting Codelists into the Registry using the Load Structures option.

In the image below you can see the content of two Codelists used in this example.

Concept Scheme

Concept Schemes are a container for Concepts. Concepts are used by Dimensions, Attributes, Measures, and Metadata Attributes to provide them with a semantic meaning. Concepts can also be used to define a default representation, for example it is possible to link the Concept of Frequency to a Codelist containing all the Frequency Codes, any structure using the Concept will inherit the default representation.

A DSD uses Concepts therefore you must have a suitable Concept Scheme available before you can create a DSD. The Concept Scheme can be created from scratch or perhaps you already have usable Concept Scheme in your Registry? Be sure to check before you move to the next step.

You can watch how to do this Creating a Concept Scheme in this video. Although this video was created for the Fusion Registry Data Essentials product, the concept is exactly the same.

Create the Data Structure Definition

To create a Data Structure Definition, from the main menu click Data and then Data Structures to go to the Overview Page. Next, click on the Maintenance button. HDSD5.PNG

The wizard will open and you can complete steps 1 - 4 as shown on the examples below.

Step 1 - High Level information


Step 2 Choose Concepts


Step 3 - Dimension Position and Content


Step 3 - Change Data Type


Step 4 Attribute Attachment
