Replication

PreviousDenormalizationNextStructure

Last updated 1 day ago

Định nghĩa:

Database Replication có thể được sử dụng trong nhiều hệ quản trị cơ sở dữ liệu, thường có mối quan hệ Master – Slave (Chủ nhân – Nô lệ)

  • Master database thường chỉ hỗ trợ các thao tác ghi dữ liệu. Tức là, tất cả các câu lệnh như INSERT, UPDATE, DELETE sẽ thực hiện trên master database.

  • Còn các Slave database sẽ copy dữ liệu từ master database và chỉ hỗ trợ các thao tác đọc dữ liệu.
