Help: Data Modelling Introduction

Classes, Attributes and Relationships are components which together define the NHS Data Model and are a suggested reference point for System Suppliers when developing systems.

Note: Data Elements and Data Sets, which define the national information requirements, reference the NHS Data Model components to form part of the wider NHS Data Model and Dictionary.
  • Demonstrations

These components are explained in a short presentation. To view this presentation, see the NHS Data Model and Dictionary Components.

NHS Data Model

The NHS Data Model provides:

  • Structure to the data
    • This enables data to be seen in context to other data items. This is achieved by grouping data into Classes and having relationships between the Classes.

  • Detailed data definitions
    • Agreed definitions provide a common basis for communication.

  • High level graphical view of data
    • The NHS Data Model and Dictionary has a small set of Diagrams which represent parts of the NHS Data Model. These diagrams show the Classes, Relationships and Cardinality.
    • For example, the Patient Pathway Diagram shows the Patient Pathways covered by the Referral To Treatment Consultant Led Waiting Times Measurement.
