Visibility over data flows is an important first step in understanding what data is at risk of being stolen or misused. To properly protect your data, you need to know the type of data, where it is, and what it is used for. Data discovery and classification tools can help. Data ...
Hardware and Software Cost:Although DBMS has several advantages over file system of data management, however all this comes with a cost. DBMS needs a dedicated hardware and software system to manage the database. Need large Storage:DBMS is usually used in the large organisations that require larg...
An entity relationship diagram (ERD), also known as an 'entity relationship model,' is a graphical representation that depicts relationships among people, objects, places, concepts or events in an information technology (IT) system.

预测查询生成的模型在此之后并不存在,也不可用于检查或调优模型。如果您需要检查模型、将评估结果与模型关联、指定特殊算法设置或使用同一模型执行多项评估查询,则必须使用 Oracle Data Miner Model Nodes 或使用一个名为 DBMS_DATA_MINING 的 Oracle Data Mining PL/SQL 程序包创建一个预定义模型。
