SV-11 – Physical Schema

Download PDF

The SV-11 defines the structure of the various kinds of system data that are utilised by the systems in the architecture.

The SV-11 provides an implementation specific data model that realises the logical data model presented in an OV-7, Information Model.

Implementation constraints may mean that one logical entity in OV-7 is in fact realised by more than one entity in SV-11 and vice versa.

Usage

The intended usage of the SV-11 includes:

  • Specifying the system data elements exchanged between systems (thus reducing the risk of interoperability errors).
  • Definition of physical data structure (input to system design).

Product Description

SV-11 allows implementation-level detail of data structures to be modelled. The view serves several purposes, including:

  • Providing the detailed information on the system data elements exchanged between systems, thus reducing the risk of interfacing errors.
  • Providing system data structures for use in the system design process, if necessary.

SV-11 is an implementation-oriented data model that is used to describe how the information requirements represented in OV-7 are actually implemented for a given solution. The entities specified in SV-11 represent data elements (from the SV-6, Systems Data Exchange Matrix).

Standards associated with entities are also often identified in the development of the SV-11 view product; these should be recorded in the TV-1 Standards Profile.

Creating a Physical Schema diagram

To create a Physical Schema diagram:

  1. Click on Physical Schema in the Action Artifact area, and then select Create New Diagram.
  2. Type the diagram name and press Enter.
  3. A blank diagram is created and you can start constructing the view. You can create DataElements and/or InformationElements. Connect elements with Associations.
