Melacak silsilah data untuk tabel BigQuery

Dokumen ini menjelaskan cara melacak asal-usul data di tabel BigQuery. Silsilah data adalah proses pelacakan asal data, bagaimana data ditransformasi, dan ke mana data berpindah dari waktu ke waktu. Memahami silsilah data sangat penting untuk memastikan kepatuhan, memecahkan masalah data, dan melakukan analisis akar masalah.

Panduan memulai ini menunjukkan cara mulai menggunakan silsilah data untuk tabel BigQuery:

  1. Salin dua tabel dari set data new_york_taxi_trips yang tersedia secara publik.

  2. Gabungkan jumlah total perjalanan taksi dari kedua tabel ke dalam tabel baru.

  3. Lihat grafik visualisasi silsilah untuk ketiga operasi.

Sebelum memulai

Siapkan project:

  1. Login ke akun Google Cloud Anda. Jika Anda baru menggunakan Google Cloud, buat akun untuk mengevaluasi performa produk kami dalam skenario dunia nyata. Pelanggan baru juga mendapatkan kredit gratis senilai $300 untuk menjalankan, menguji, dan men-deploy workload.

  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, BigQuery, and Data Lineage 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.
