Java

לפני שמנסים את הדוגמה הזו, צריך לפעול לפי הוראות ההגדרה Javaבמדריך למתחילים בנושא Dataplex Universal Catalog באמצעות ספריות לקוח. מידע נוסף מופיע במאמרי העזרה של Dataplex Universal Catalog Java API.

כדי לבצע אימות ב-Dataplex Universal Catalog, צריך להגדיר את Application Default Credentials. מידע נוסף זמין במאמר הגדרת אימות לסביבת פיתוח מקומית.
