Answer 2

Describes a fundamental architecture upon which other, more specific, architectures can be based.

Question 3

Major characteristics of a Foundation Architecture

Answer 3

• It reflects general computing requirements
• It reflects general building blocks
• It defines technology standards for implementing these building blocks
• It provides direction for products and services
• It reflects the function of a complete, robust computing environment that can be used as a foundation
• It provides open system standards, directions, and recommendations
• It reflects directions and strategies

Question 4

The TRM has two main components

Answer 4

1. A taxonomy that defines terminology, and provides a coherent description of the components and conceptual structure of an information system
2. A model, with an associated TRM graphic, that provides a visual representation of the taxonomy, as an aid to understanding

Question 5

Integrated Information Infrastructure Reference Model

Answer 5

The III-RM is a reference model that focuses on the Application Software space and is a “Common Systems Architecture” in Enterprise Continuum terms

Question 6

Integrated Information Infrastructure Reference Model

Answer 6

• Is fundamentally an Application Architecture reference model – a model of the application components and application services software essential for integrated information infrastructure.
• It includes information provider and consumer applications, as well as brokering applications

Question 7

Boundaryless Information Flow

Answer 7

Is essentially the problem of getting information to the right people at the right time in a secure, reliable manner, in order to support the operations that are core to the extended enterprise.

Question 8

The customer enterprise could gain significant operational efficiencies and improve the many different business processes of the enterprise – both internal processes, and those spanning the key interactions with suppliers, customers, and partners – if only it could provide staff with

Answer 8

• Integrated information so that different and potentially conflicting pieces of information are not distributed throughout different systems
• Integrated access to that information so that staff can access all the information they need and have a right to, through one convenient interface
