database definition file

基本解釋

If information is stored in a remote database, it gets downloaded to the kernel based on definition in /etc/nscontrol.conf file.
如果信息存儲于一個遠(yuǎn)端數(shù)據(jù)庫，則會基于 /etc/nscontrol.conf 文件內(nèi)的定義將其下載到內(nèi)核。
Even still, with physical data models you can reverse engineer from the actual database or from the data definition language (DDL) file.
還可以對實(shí)際數(shù)據(jù)庫或數(shù)據(jù)定義語言（DDL）文件進(jìn)行反向工程，生成物理數(shù)據(jù)模型。
Selecting the Orchestrate Schema Definitions menu item starts the process of importing the file definition or database table schema using the PX operators.
選擇 Orchestrate Schema Definitions 菜單項(xiàng)將開始使用 PX 運(yùn)算符導(dǎo)入文件定義或數(shù)據(jù)庫表模式。
