Explanation / Answer
Business Modeling Tools
This category covers tools for the modeling of business rules and business process rules.
Business modeling describes and documents the business in a comprehensive knowledge base. It establishes a consensus among general management of the business direction, organization, processes, information requirements, and the current environment of the business. Perhaps most importantly, this understanding is documented in a common, business-oriented format to be utilized for subsequent enhancement.
Design Modeling Tools
This category covers tools for designing, defining, and documenting the most pertinent IT elements of the business based upon the business and business process rules. Examples of elements to be designed include: connections between people, organizations, workflows and computers; data and object models; physical data translation and translation rules; and constraints.
Implementation and Construction Tools
Implementation tools enable timely development of re-usable processes, applications, and application services. Such tools include intelligent browsers, data manipulation language compilers and optimizers, distributed application compilers and debuggers, heterogeneous client and server development tools, policy definition tools, and workflow script generation tools.
Data Modeling Tools
Deployment Tools
Deployment tools are necessary to move implemented software from the development environment into the operational environment.
Libraries
This component includes re-usable libraries of software that use the standards of the operational environment.
Management Utilities
This category covers applications that take the form of utilities for operations, administration, and systems management, and for the management of data based on availability and cost requirements. Such utilities may execute in an attended or an unattended environment.
Operations, Administration, and Management (OA&M) Utilities
The OA&M component covers traditional systems management and administration utilities that manage business rules and information objects. Examples include: utilities for installation, copyright and license management; and miscellaneous administration, configuration, and registration functions. Additionally there are utilities for the control of service billing, service triggering, and account management.
Quality of Service Manager Utilities
These include health monitoring and management utilities.
Copy Management Utilities
Copy Management utilities are those that manage data movement from any given operational system to necessary distribution points in the enterprise, in order to ensure the maximum leverage of operational systems data. They also include tools that detect and flag poor quality data.
Storage Management Utilities
These are utilities that provide least-cost data storage management. Storage management utilities support the wide variety of storage mechanisms and are connected to file, object, and database systems.
