创建和使用业务术语库

本文档介绍了如何使用 Knowledge Catalog 为数据资产建立标准化词汇表。通过创建业务术语库，您可以减少歧义，并提高整个组织的数据发现能力。

本快速入门使用零售行业场景和 BigQuery 中的示例数据，向您展示如何完成以下目标：

  1. 为零售运营创建业务术语库。
  2. 构建产品目录管理系统类别层次结构。
  3. 定义业务术语，例如“安全库存水平”。
  4. 将业务术语附加到 BigQuery 列。
  5. 使用业务上下文搜索数据。

  2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    Go to project selector

  3. If you're using an existing project for this guide, verify that you have the permissions required to complete this guide. If you created a new project, then you already have the required permissions.

  4. Verify that billing is enabled for your Google Cloud project.

  5. Enable the Dataplex and BigQuery APIs.

    Roles required to enable APIs

    To enable APIs, you need the serviceusage.services.enable permission. If you created the project, then you likely already have this permission through the Owner role (roles/owner). Otherwise, you can get this permission through the Service Usage Admin role (roles/serviceusage.serviceUsageAdmin). Learn how to grant roles.

    Enable the APIs

  6. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.
