An  Application is a Business Software System that provides a set of  Functionality(ies) that End Users see as a single unit.

Essentially  Applications are architectural constructions resulting from the combinaison of the following four criteria:

1) A group of  Functionality that End Users see as a single unit.

2) A managed asset (Managed Application) associated with a budget line in the context of an Application Portfolio.

3) A body of code that is seen by developers as a single unit.

4) A group of deployable software units (Deployable Application Packages) that must be installed together on one or multiple execution nodes (Computing System).

 Application is a Mezzo enterprise asset  that sits between Application System and Application Component in the decomposition of Business Software Systems.

Example: " Payroll" is an  Application that is part an " HR System" which is an Application System.

The "Payroll"  Application includes, among other things, the "Salary and Wage Calculation" Application Component.

A  Computer Server is a Computing Device which provides processing, storage, and network connectivity services to other Computing Devices on a Computer Network.

As a Computing System, it can host data and run Application code..

A  Data Center is a Facility composed of networked computers, storage systems and computing infrastructure that enterprises use to organize, process, store and disseminate large amounts of data.

Business Operations rely heavily upon the applications, services and data contained within a  Data Center, making it a focal point and critical asset for everyday operations.

A  Deployed Data Store is a repository for storing, managing and distributing data sets on an enterprise level. It is a broad term that incorporates all types of data that is produced, stored and used by an organization.

 Deployed Data Stores exist wihin a Data Center. They can be hosted on Deployed Server.

A  Facility is a class of System of Resources that represents the physical infrastructure (e.g., buildings, plants, warehouses, offices, or laboratories) that houses personnel, equipment, and processes, enabling enterprise's activities.

Examples:

- Data Center

- Factory

- Outlet

- Outdoors construction

A  Location is a geopolitical location anywhere on the earth.

Examples:

- France

- Paris

- Washington DC

- Cairo

- Buenos-Aires

- Asia

A  Software Technology is an elementary Software Technology System  used as an enabler by Software Modules.

Examples :

- Application server,

- Message server,

- Storage,

- Business information sharing,

- Operating systems,

- Navigators, etc

A  System of Systems is a Macro Capability Configuration that combine several System of Resources to deliver a common high level  Business Capability.

Examples:

- Air traffic control system

- Smart city system

- Health Care System

- Search and Resue system (SAR)

- Naval squadron consisting of an aircraft carrier, its escort ships and its C5ISR capabilities.
