This section describes the roles of different users and helps new users understand which prerequisites are required for each business service activity.

This section covers the following topics:

• Introduction

• Understanding Prerequisites

• Types of Security Available with EntireX

• Summary of Tasks

Introduction

With all the functionality and components of Natural Business Services, it is important to understand which components are required for your scenario. Every development activity requires the Business Service repository and the Administration subsystem and every consumer requires an existing business service. All business services are created using the Natural Business Services Natural plug-in. As this plug-in does not require EntireX, you can use Natural Development Server (NDV) for development. EntireX is required for runtime environments.

At a high level, the minimum tasks required to produce a viable business service are:

1. Install Natural Business Services on the client and the server.

2. Ensure connectivity exists through NDV (for development activities) and EntireX (for development and/or runtime activities).

3. Ensure security is set for users and the development environments.

4. Create the business service.

5. Consume the business service through one of the following options:

   • Java (via Eclipse)

   • Visual Studio

6. Invoke the business service through one of the consumers.

Note:
Depending on your configuration, use either NSC or APPL with Natural Development Server (NDV).

As most sites have both a production and development environment, the decision about which type of security to use can be postponed for a while (although you must eventually choose a security type).
