The CSDM explained—Aligning IT to business strategy
CSDM 解释 — 使 IT 与业务战略保持一致
A reactive approach to digital products and delivery can dominate without an IT focus on standardization, integration, and application of a common approach. CSDM helps you connect terminology to help make decisions for strategy, planning, developing, troubleshooting, root cause analysis, and executing changes.
如果不将 IT 部门重点放在通用方法的标准化、集成和应用上,那么对数字产品和交付的反应性方法可能会占据主导地位。CSDM 可帮助您连接术语,以帮助做出有关战略、规划、开发、故障排除、根本原因分析和执行更改的决策。
CSDM is all about doing CMDB right
CSDM就是要把CMDB做好
CSDM is considered the best practice for CMDB modeling and management—it provides direction on modeling and comes with a standardized set of definitions. It is a connection between business and technical perspectives with mapping and relationships. It provides visibility into application and service data from varying domains, consolidating everything into a single view. This gives your organization the opportunity to align your IT and company strategies. CMDB with a high-quality CSDM also provides multiple benefits like faster incident resolutions, better security, and better judgment of the impact of change.
CSDM 被认为是 CMDB 建模和管理的最佳实践 — 它提供了建模方向,并附带了一套标准化的定义。它是业务和技术视角与映射和关系之间的连接。它提供了对来自不同域的应用程序和服务数据的可见性,将所有内容整合到单个视图中。这使您的组织有机会调整您的 IT 和公司战略。具有高质量CSDM的CMDB还提供了多种好处,例如更快的事件解决,更好的安全性以及对变更影响的更好判断。
Benefits of the CSDM CSDM的好处
The common services data model can act as a blueprint to map your IT services on the ServiceNow platform—it is a CMDB-based framework that outlines where to place data for the other products that are in use. CDSM is also a standard for ServiceNow products that use CMDB. If you follow the CDSM framework, you’ll ensure that the data in the application maps to the correct CMDB table which minimizes duplicate, incorrect, and out-of-date data.
通用服务数据模型可以充当在 ServiceNow 平台上映射 IT 服务的蓝图 — 它是一个基于 CMDB 的框架,概述了将正在使用的其他产品的数据放置在何处。CDSM也是使用CMDB的ServiceNow产品的标准。如果遵循 CDSM 框架,则将确保应用程序中的数据映射到正确的 CMDB 表,从而最大程度地减少重复、不正确和过时的数据。

Challenges of CSDM CSDM的挑战
While CSDM provides certain clear advantages, some organizations find themselves poorly prepared to get the most out of the common services data model. When this happens, the issue can usually be traced back to one or more of the following problems:
虽然 CSDM 提供了某些明显的优势,但一些组织发现自己在充分利用通用服务数据模型方面准备不足。发生这种情况时,问题通常可以追溯到以下一个或多个问题:
How to get started with CSDM
如何开始使用 CSDM
It isn’t advisable to implement each CSDM element all at once. Instead, approach CSDM in stages, and don’t feel like you have to hit every stage for every application or service. ServiceNow defines these stages as Foundation, Crawl, Walk, Run, and Fly. Each stage is explained below:
不建议一次实现每个 CSDM 元素。相反,分阶段处理 CSDM,不要觉得你必须为每个应用程序或服务达到每个阶段。ServiceNow 将这些阶段定义为“基础”、“爬网”、“行走”、“运行”和“飞行”。每个阶段解释如下:
How do I migrate CSDM-related data to the recommended tables?
如何将 CSDM 相关数据迁移到推荐的表中?
Why should I use the CSDM?

框架领域模型
Each domain in the CSDM conceptual model is associated with one or more products, services, or service types, which you can extend as needed.
CSDM 概念模型中的每个域都与一个或多个产品、服务或服务类型相关联,您可以根据需要扩展这些产品、服务或服务类型。
A service enables you to achieve the outcomes that you want with minimal risks and without incurring costs. This definition is consistent with the base definition of “service” in ITIL v3 and IT4IT. Services typically have three components: the interaction, the offering, and the service system.
服务使您能够以最小的风险实现所需的结果,而不会产生成本。此定义与 ITIL v3 和 IT4IT 中“服务”的基本定义一致。服务通常有三个组件:交互、产品和服务系统。
