CIM (Common Information Model) A
hierarchical object-based model developed by
the DMTF that defines a large number of
concepts common to most computer systems.
See Common Information Model.
CIM client A client application that issues
CIM operation requests over HTTP and
processes the responses.
CIM Object Manager (CIMOM) Manages
CIM objects in an HP WBEM-enabled
system. CIMOM receives and processes CIM
operation requests and issues responses.
CIM Object Manager repository A
central storage area managed by the
Common Information Model Object Manager
(CIM Object Manager). This repository
contains the definitions of classes and
instances that represent managed objects
and the relationships among them. Also see
repository.
CIM schema A collection of class definitions
used to represent managed objects that
occur in every management environment.
Also see core model, common model, and
extension schema.
cipher A key-selected transformation
between plain text and cipher text. With a
good cipher, the secret information inside the
cipher remains hidden, even when the cipher
text is stored or transmitted.
class A collection of instances, all of which
support a common type; that is, a set of
properties and methods. The common
properties and methods are defined as
features of the class. For example, the class
called Modem represents all the modems
present in a system.
Common Information Model (CIM) A
common data model of an implementation-
neutral schema for describing overall
management information in a
network/enterprise environment.
CIM is comprised of a Specification and a
Schema. The Specification defines the details
for integration with other management
models defined by the DMTF, such as
SNMPs MIBs or the DMI’s MIFs. The
Schema provides the actual model
descriptions.
Common Information Model Object
Manager (CIM Object Manager)
A
component in the CIM management
infrastructure that handles the interaction
between management applications and
clients.
common model The second layer of the
CIM schema, which includes a series of
domain-specific but platform-independent
classes. The domains are systems, networks,
applications, and other management-related
data. The common model is derived from the
core model. Also see extension schema.
core model The first layer of the CIM
schema, which includes the top-level classes
and their properties and associations. The
core model sets the conceptual framework
for the schema of the rest of the managed
environment. Systems, applications,
networks and related information are
modeled as extensions to the core model.
