Indexes giúp truy xuất dữ liệu nhanh hơn, giảm quét toàn bảng. Có hai loại chính: hash (tốt cho tra cứu chính xác) và B‑tree/B+‑tree (hỗ trợ tìm kiếm theo khoảng). DBMS tự động duy trì index khi INSERT/UPDATE/DELETE, đổi lại tốc độ ghi chậm hơn. DBMS còn cung cấp API, kiểm soát đồng thời, phục hồi lỗi, biến file lưu trữ thành hệ thống quản lý dữ liệu mạnh. #Database #DBMS #Index #CSDL #Côngnghệ

Mal ne Fragen an die Datenbankexperten:
Ich schätze 90% aller Datenbankanwendungen brauchen keine Spezialfunktionen. Warum setzen viele Entwickler trotzdem #Microsoft oder #Oracle ein, anstatt freie Alternativen wie #Postgresql oder #MariaDB?

Das erzeugt doch weniger Abhängigkeit und spart den Kunden Lizenzgebühren.
