Describing an Application System Environment with Hopex IT Architecture
An application system environment allows presenting the other application systems, applications or microservices with which this application system can interact.
Accessing the list of application system environments
To access the list of application system environments from System the Application Systems navigation menu:
Open the
Environments page of the application system of your choice.
The list of application system environments appears in the edit area.
Creating an application system environment
To create an Application System Environment from the Application Systems navigation menu:
1. Open the Environments page of the application system of your choice.
The list of application system environments appears in the edit area.
2. Click New.
The new application system environment appears in the list, it has the name of the application system followed by "Environment".
Application system environment properties
The Characteristics properties page for an application system environment provides access to:
• its Owner, by default during creation of an application system environment, the current library.
• its Name,
• the text of its Description.
Application system environment diagrams
An application system environment is described by several types of diagram:
• an Application System Environment diagram describes the exchanges between the subject application system and its partners in a specific context.
• a scenario of application system environment flows presents the flows exchanged between the application services or the microservices used by the described application system in a specific context.
Describing an application system environment diagram
An application system environment is described by an application system environment diagram that describes the service interactions between the internal application systems, its users and the partner application systems.
Application system environment diagram for the Purchasing Requests
Purchase requests are formulated by clients or employed using the "Purchasing Management Platform".
The "Purchasing Management Platform” application system uses an internal application system for the “Payment management” and a partner application system for the “Delivery”.
The elements of an application system environment diagram are:
• the main application system principal described by the environment.
An application system is an assembly of other application systems, applications and end users interacting with application components to implement one or several functions.
• partner application systems that represent the other application system with which the main application system described by the environment interacts.
In this example, this concerns two loan services offered to individuals and companies.
A partner application system is an application system external to the environment of the described application service. The partner application system can be a service supplier or a service consumer with respect to application system users.
• The categories of users of services provided by the environment are represented either by an Org-Unit or by a Position Type.
An org-unit represents a person or a group of persons that intervenes in the enterprise business processes or information system. An org-unit can be internal or external to the enterprise. An internal org-unit is an organizational element of enterprise structure such as a management, department, or job function. It is defined at a level depending on the degree of detail to be provided on the organization (see org-unit type). Example: financial management, sales management, marketing department, account manager. An external org-unit is an external entity that exchanges flows with the enterprise. Example: customer, supplier, government office.
A position type represents a status assigned to an individual or a group of individuals with the aim of defining an organization or a hierarchy.
This concerns two user categories: individuals and companies.
• Service interactions between components
A Service Interaction represents an interaction for service purpose between entities in a specific context inside or outside a company. These entities can be enterprise org-units, applications, activities or processes, as well as external org-units. The content of this interaction is described in a service interface.
Describing a Scenario of Application System Environment Flows
A scenario of application system environment represents the flows exchanged between the components of the application system environment.
The elements of a scenario of application system environment are:
• the main application system principal described by the environment.
An application system is an assembly of other application systems, applications and end users interacting with application components to implement one or several functions.
• partner application systems that represent the other application system with which the main application system described by the environment interacts.
A partner application system is an application system external to the environment of the described application service. The partner application system can be a service supplier or a service consumer with respect to application system users.
• End User Participants that represent the categories of users of application system provided by the environment.
• The categories of users of services provided by the environment are represented either by an Org-Unit or by a Position Type.
An org-unit represents a person or a group of persons that intervenes in the enterprise business processes or information system. An org-unit can be internal or external to the enterprise. An internal org-unit is an organizational element of enterprise structure such as a management, department, or job function. It is defined at a level depending on the degree of detail to be provided on the organization (see org-unit type). Example: financial management, sales management, marketing department, account manager. An external org-unit is an external entity that exchanges flows with the enterprise. Example: customer, supplier, government office.
A position type represents a status assigned to an individual or a group of individuals with the aim of defining an organization or a hierarchy.
• Service interactions between components
A Service Interaction represents an interaction for service purpose between entities in a specific context inside or outside a company. These entities can be enterprise org-units, applications, activities or processes, as well as external org-units. The content of this interaction is described in a service interface.
