System Management Lesson 01. Introduction
1. Briefly describe the development history of Oracle relational database management system.
2. Please explain in detail the relationship between the tables of the HR sample program.
3. Please translate the following content into Chinese:
Oracle Database 10g was the first database management system designed for grid computing.
Oracle Database 11g consolidates and extends Oracle’s unique ability to deliver the benefits of grid computing, transforming data centers from silos of isolated system resources to shared pools of servers and storage.
Oracle Database 12c and Enterprise Manager Cloud Control are designed for cloud computing. Cloud computing creates a complete, pre-integrated, off-the-shelf private cloud solution that allows you to quickly transform the enterprise data center into a private cloud.
The key benefits are the following:
• Reduce server sprawl and improve CPU utilization by consolidating on fewer servers.
• Reduce the amount of time a DBA spends installing and configuring databases, by automating deployment of standard database configurations.
• A single console manages the entire Cloud life cycle—plan, set up, deliver, and operate.
• Prevent resource hogging by setting quotas for individual users.
• Forecast future resource needs by analyzing trending reports.
Compute chargeback based on performance and configuration metrics.
Oracle Database10g is the first database management system for grid computing.
Oracle Database 11g integrates and expands Oracle's unique ability to provide the benefits of grid computing, transforming the data center from an isolated system resource library to a shared server and storage pool.
Oracle Database 12c and Enterprise Management Cloud Control are designed for cloud computing. Cloud computing creates a complete, pre-integrated, off-the-shelf private cloud solution that allows you to quickly convert an enterprise data center into a private cloud.
The main benefits are as follows:
• Reduce server expansion and increase CPU utilization by consolidating on fewer servers.
• Reduce the time for DBA to install and configure the database by automating the deployment of standard database configurations.
• A single console manages the entire cloud lifecycle planning, setup, delivery, and operation.
• Prevent resource consumption by setting quotas for individual users.
• Forecast future resource demand through analysis of trend reports.
According to the performance and configuration indicators, the storage capacity is charged.
