The first attempt to back up an Oracle database to the AWS Cloud was typically backed up to a tape library or disk, and now it's easier to have a cloud. This is primarily backed up using AWS's S3 storage as an SBT device. As for what is AWS, what is S3, please refer to: http://www.amazonaws.cn/products/specific steps are as follows:Prerequisites: You will have an AWS Accunt (AWS access key ID and AWS secret key) and you will need to have Oracle's OTN

History of motor Development information readingMotor in machinery. Metallurgical, textile, coal, petroleum, chemical, transportation and household appliances and other fields are the main power equipment of various production machinery. The control motor is also an important and indispensable component in the automatic control system of national defense and civil. Motor is an irreplaceable important role in the national economy.I searched the internet for the growth chart of the national total

from the textbook of electromechanical drive control, it is easy to find the definition of the concept of electromechanical drive control, which represents a complete set of electrical systems that represent the motors that drive production machinery and control motors. The purpose of this technology is to convert electrical energy into mechanical energy, to achieve the start, stop and speed regulation of p

Drive motor or control motor for industrial or life applications The application of servo motor in robot manufacture. High-precision robots, for example, will install high-precision, total-line servo motors. The switched reluctance motor (switched reluctance DRIVE:SRD) is the newest generation stepless speed regulation system developed after the frequency conversion speed control system and brushless DC motor speed control system.
