(Pratinjau) Pengelola data yang terkait dengan entri data. Pengelola data untuk
entri data dapat dihubungi untuk meminta informasi selengkapnya tentang entri data. Pengelola data tidak memerlukan peran IAM tertentu. Anda dapat menambahkan pengguna dengan akun email non-Google sebagai pengelola data untuk entri data. Pengelola data tidak dapat melakukan aktivitas terkait project apa pun dalam konsol, kecuali jika pengguna diberi izin IAM eksplisit.
(Pratinjau) Ringkasan teks panjang entri data yang dapat menyertakan gambar, tabel, dan link.
Menelusuri metadata bisnis
Metadata bisnis selalu ditautkan ke entri metadata teknis. Metadata
bisnis dapat ditelusuri tanpa menggunakan sintaksis apa pun. Satu-satunya pengecualian untuk penelusuran ini adalah tag, yang memerlukan penggunaan sintaksis tag.
Berikut adalah daftar informasi penting untuk penelusuran metadata
bisnis untuk entri data Data Catalog:
Anda dapat menggunakan alamat email atau nama pengelola data, dan teks dari deskripsi ringkasan entri data untuk menelusuri entri data Data Catalog yang relevan.
Data Catalog tidak mendukung penelusuran gambar yang terkait dengan deskripsi
teks panjang.
Jika Anda menghapus entri data, lalu membuatnya ulang dalam waktu 32 hari dengan ID yang sama persis, ringkasan dan pengelola data entri data akan dipulihkan.
Batas untuk metadata bisnis
Untuk mengetahui informasi tentang batas metadata bisnis, lihat Kuota dan batas.
Langkah selanjutnya
Terapkan tag, ringkasan, dan pengelola data ke entri.

A data steward for a\n data entry can be contacted to request more information about the data entry. A\n data steward does not require a specific IAM role. You can add a\n user with a non-Google email account as a data steward for a data entry. A data\n steward can't perform any project-related activity within the console, unless\n the user is provided with explicit IAM permissions.\n\n- (Preview) **Rich text overview** of a data entry that can include images,\n tables, and links.\n\n### Search for business metadata\n\nBusiness metadata is always linked to a technical metadata entry. Business\nmetadata is searchable without the use of any syntax. The only exception to this\nsearch is tags, which requires the use of [tag syntax](/data-catalog/docs/how-to/search-reference).\n\nThe following is a list of important information for the business metadata\nsearch for a Data Catalog data entry:\n\n- You can use email addresses or names of data stewards, and text from the data entry **overview** descriptions to search for relevant Data Catalog data entries.\n- Data Catalog doesn't support image search related to the rich text descriptions.\n- If you delete a data entry and then recreate it within 32 days with the exact same identifier, then the overview and data steward of the data entry are restored.\n\n### Limits for business metadata\n\nFor information about the limits for business metadata, see [Quotas and limits](/data-catalog/docs/resources/quotas).\n\nWhat's next\n-----------\n\n- [Apply](/data-catalog/docs/quickstarts/quickstart-search-tag) a tag, an\n overview, and a data steward to an entry.\n\n- Learn more about [tag templates and tags](/data-catalog/docs/tags-and-tag-templates) ."]]
