Installation of Oracle Database 10g Express Edition is extremely easy and can be done in less than 15 minutes.Sheila needs to install Oracle Database 10g Express Edition on both Linux and Windows platforms because she will be working with two groups that want to operate independently.
Watch Sheila install Oracle Database 10g Express Edition on Linux.
Launch Demonstration
In this module, you learn how to log in to the Oracle Database 10g Express Edition browser-based user interface, create administration and database users, and load some employee data.
Users access Oracle Database 10g Express Edition through database user accounts. Some of these accounts are automatically created administrative accounts—accounts with database administration privileges. You log in with these accounts to create and manage other user accounts and to maintain database security.
Oracle Database XE provides an organized mechanism for storing, managing, and retrieving information.Tables are the basic storage structure for holding business data. In this module, you learn how to create tables and work with them.
You may want to modify data entered in tables. You may also want to maintain integrity with the data. Sometimes, you may want to remove tables that are no longer useful.
Now that Sheila has the Oracle Database XE software installed and working, and has familiarized herself with the tables in the HR schema, her next task is to build some tables and database objects. In the demonstrations, you watch Sheila create and modify tables, manage constraints, and remove tables.
Accessing Data
In this module, you learn how to retrieve data from tables. The SQL SELECT statement is used to access and report data back from the XE tables. This is known as "querying" the data. In XE, you can either write SELECT statements using the SQL Workshop tool, or you can use the Query Builder tool to build queries with a GUI interface.
You will watch Sheila write several reports for the Human Resources department. Sheila will use both the SQL SELECT statement in the SQL Workshop tool and the Query Builder tool to access data in the Human Resources tables.
