# Objectives, Audiences and Uses

## Objectives

The key objectives of this guide are to:

1. Enhance understanding of the logical design of SNOMED CT;
2. Demonstrate the feasibility of effective terminology access;
3. Enable terminology access for practical exercises;
4. Provide a starting point for further development.

## Audiences

There are three distinct target audiences for this guide:

1. Designers and developers
   * The guide provides practical examples of the ways in which features in SNOMED CT can be accessed using a widely understood technology;
   * It demonstrates services that designers and developers should consider including in their terminology server developments;
   * It can also be used to inform terminology server requirements for system access to SNOMED CT.
2. People seeking practical ways to access SNOMED CT content and reference sets:
   * The demonstrator documented in this guide provides ways to access SNOMED CT content and reference sets using simple SQL queries.
   * This type of access can complement the use of a SNOMED CT browser or other specific tools by enabling customizable access to specific collections of terminology content.
3. Anyone interested in SNOMED CT who is seeking a practical example of accessing the terminology in ways described in other specifications and guides:
   * Although many SNOMED CT tools deliver user-friendly services for well-established use cases, some use cases require customized services that are not readily available from existing tools.
   * For example, the full version of the demonstration database allows queries to be written that report the history of changes that impact a defined set of SNOMED CT components.
