• Server

A Server is a machine on which the Client Service, Advanced Server Service, Communication Service, Task Scheduler, Mobile Notification Service, and Workflow Engine are installed. If the load balancing feature is enabled during the Farm configuration, the Enterprise Edition License is acquired and the Advanced Server service is installed and enabled. These services can be installed on a single server or on multiple servers. In the case of Developer and Professional Editions, all services are installed on the same server, whereas in the case of Enterprise Edition, the services are installed on multiple servers.

The primary role of the Server is to control workflow execution and schedule tasks. The Workflow Engine and the Task Scheduler are services that control workflow execution. The Communication service manages communication and notifications. The Advanced Server service enables load balancing.

• Client

A Client is a machine in which the Central Configuration Site and the Enterprise Console are enabled. If the load balancing feature is enabled during the Farm configuration, the Enterprise Edition License is acquired and the Advanced Server service is installed and enabled

• Farm Database

A Farm Database is a machine that contains information about the Enterprise Console, location of the Central Configuration Site, and configuration settings at a global and server (machine) level. These settings are specified in the Farm Configuration Wizard database.

• Central Configuration Site

The Central Configuration Site enables you to define, create and manage repositories for workflows and execute them. A Repository refers to a database that contains workflow definitions, queues, calendars, settings, and workflow execution data for an application.

The location and settings for the Central Configuration Site are specified from the Farm Configuration Wizard. The Repository settings are stored in the database specified for the repository.

• Enterprise Console

This is a Web-based interface that allows authorized users to build workflow driven applications and also allows users to participate in these applications. The console enables central administration of all workflows associated with a repository. Activities that can be performed from the Enterprise Console include workflow categorization, workflow design, associating workflows with SharePoint sites, lists, events, initiating workflows for new workflow creation, publishing workflows, creation, management and association of Forms with workflows and viewing reports. The Enterprise Console also enables administrators to set up and manage queues and calendars for use in workflows.

• One Enterprise Console can be mapped to one or more Repositories; however users can login only to their respective Repositories.
• One or more Enterprise Consoles can be configured for the same repository.
• The Enterprise Console can be configured for more than one repository.
• The Enterprise Console is defined and managed using the Farm Configuration Wizard.

• Repository

A Repository is a database that contains workflow definitions, queues, calendars, settings, workflow execution data and Business Activity Monitoring (BAM) data. Data Sources for Repositories are defined in the Central Configuration Site.

• Forms

The Forms is an easy to use drag and drop interface used for designing forms. You can use forms designer to quickly design forms, maintain form templates, and define business logic. The Forms are used to trigger Workflows.

• Farm

A Farm is a collection of Servers and Client services working as a single logical entity to provide the AVEVA Workflow Management solution. The Farm configuration is achieved through the Farm configuration wizard.

A Repository can also be created for each client in a hosted environment (Application Service Provider environment).
