  3. Background The Aspect Object Architecture Supports the IndustrialIT concept, by defining a platform, concepts, and rules, for development of IndustrialIT compliant products

  4. Background The Aspect Object Architecture Requirements: • Make it possible to build a system that provides functionality for process automation, asset optimization and collaborative business processes, yet is easily understood and efficient to use • Be optimized for the performance, predictability, reliability and availability that is required for high performance real-time process control • Provide security mechanisms that allow all operations to be access controlled and logged to comply with regulatory requirements

  5. Background The Aspect Object Architecture Requirements, cont. • Scale competitively from very small (<100 objects) to very large (>200,000 objects) • Provide strong support for building reusable application solutions • Allow software and equipment of different origin and with different internal implementation technologies to be integrated and work together as one consistent and integrated system • Allow new functionality to be incrementally added to and integrated with the system without changing or recompiling existing software • Efficiently support development by independent groupsin a distributed organization

  18. Aspect Objects Aspect Object Types • An Aspect Object type defines certain characteristics that are common to several Aspect Object instances • Efficient re-use of proven solutions • When an instance of an object type is created, the aspects that are defined in the object type are instantiated and associated with it • You can add aspects to a specific instance • You can replace inherited aspects with instance specific aspects of the same type • You can not delete aspects that were inherited from the object type

  21. Architecture The Aspect Framework • The Aspect Object Architecture builds on the concepts of Aspect Objects and Afw Services • The rules and conventions defined by the architecture are implemented by the Aspect Framework (Afw) Aspect Framework (Afw)

  22. Architecture Aspect systems Connectivity components Aspect Framework (Afw) Adding functionality • Server and workplace functionality is provided by applications which present themselves as Aspect Systems • The control layer is connected to the server layer through connectivity components

  23. Architecture Aspect System - Integration levels 0. User Interface Wrapping:The application provides its user interface as an ActiveX, ASP/HTML page, Active Document, OLE Server, or Windows application. This is the lowest level of integration, allowing a user to access the application’s user interface through Aspect Objects, but providing no other integration benefits 1. User Interface Integration: The application recognizes itself as an aspect system, and it supports basic aspect operations, such as Create/Delete. When you navigate to the aspect you end up in a context which is relevant to the current Aspect Object 2. Navigation Integration: The aspect system recognizes the fact that there are also other aspect systems. It supports context menus, making it possible to navigate to other aspects directly from within the application. It also provides contents for other aspect systems to include in context menus 3. Engineering Integration: The aspect system supports all aspect operations, including Copy/Paste, Export/Import, Inheritance and Version Handling. The aspect system has knowledge about object type libraries and structures 4. Administrative Integration: The aspect system supports integrated administration, including install, backup/restore, and NLS translation 5. Data Management Integration: The aspect system supports life-cycle management, and transaction handling with roll-back
