CIM: Level 1 Model M3 CIM captures business requirements in the language that is familiar to the end user of

the solution and the business domain experts

Computation Independent Model (CIM)

Domain Model describes the problem domain in terms of

business concepts and reflects a precise model of domain

vocabularies and terminologies

Domain Model describes the problem domain in terms of

business concepts and reflects a precise model of domain

vocabularies and terminologies

Use Case Model describes functionality of a system in terms of use cases/user tasks/actions showing

interactions between the users and the system

Use Case Model describes functionality of a system in terms of use cases/user tasks/actions showing

interactions between the users and the system

Activity Model describes behaviors of a system in terms of activities, actions, controls,

and data flows reflecting organizational structures,

business processes, work flows, and procedures

Activity Model describes behaviors of a system in terms of activities, actions, controls,

and data flows reflecting organizational structures,

business processes, work flows, and procedures

PIM: Level 2 Model M3 PIM specifies the solution that is not tied to the choice of a specific computing

platform; however it must comply with the system requirements specified in the CIM

Platform Independent Model (PIM)

Type Model specifies domain objects in terms of types, attributes, associations,

collaborations, and is used to discover core business types

and business interfaces

Type Model specifies domain objects in terms of types, attributes, associations,

collaborations, and is used to discover core business types

and business interfaces

Component Model specifies the scope, responsibilities, and

supported interfaces for the discovered components, and

the way their services are composed to support the

system

Component Model specifies the scope, responsibilities, and

supported interfaces for the discovered components, and

the way their services are composed to support the

system

Service Model specifies services which provide reusable

business functionality and includes services that are

affected by the components and interfaces specified in the

component model

PSM: Level 3 Model

M3 PSM specifies system implementation and design in the form of platform-dependent model that adds details to the PIM for a specific computing platform, and specifies how that system uses the selected platform

Platform Specific Model (PSM)

Data Model represents the structure and relationship of

data in information repositories, and shows the persisted entities in their corresponding domains and the relationships amongst

persisted elements

data in information repositories, and shows the persisted entities in their corresponding domains and the relationships amongst

Runtime Model illustrates the structure of the elements that

have runtime presence such as threads, processes, DLLs, objects, components, etc.

during their execution and their interactions

Deployment Model depicts how the system is deployed to

hardware infrastructure and how the system artifacts are

gathered in the file system including the structure of

directories, files, etc.
