Data Loading Methods Several methods are available for loading data into tables in an Oracle database. Of the methods available, Direct Load insert and SQL*Loader are discussed here. Export and Import are covered in the Oracle9i Database Administration Fundamentals II course. SQL*Loader SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that places little limitation on the format of the data in the data file. Direct Load Direct Load insert can be used to copy data from one table to another table within the same database.

Built-In Database Objects In addition to creating the database files, several other structures are created. Data dictionary: Contains descriptions of the objects in the database Dynamic performance tables: Contains information used by the database administrator (DBA) to monitor and tune the database and instance PL/SQL packages: Program units adding functionality to the database. These packages are created when the catproc.sql script is run after the CREATE DATABASE command. PL/SQL packages will not be discussed within the scope of this course.

Overview of Primary Components The Oracle architecture includes a number of primary components, which are discussed further in this lesson. Oracle server: There are several files, processes, and memory structures in an Oracle server; however, not all of them are used when processing a SQL statement. Some are used to improve the performance of the database, to ensure that the database can be recovered in the event of a software or hardware error, or to perform other tasks necessary to maintain the database. The Oracle server consists of an Oracle instance and an Oracle database.
