Creating and Populating Tables:

Once you have created a user account, you can begin creating tables in Oracle. Tables are where data is stored in an Oracle database. Each table has a name and a set of columns. Columns represent the fields of data that are stored in a table.

You can create tables using the Oracle SQL Developer tool, which is included with the Oracle software. To create a table, you will need to specify the name of the table and the columns that it will contain.

After you have created a table, you can populate it with data. To do this, you will need to use SQL INSERT statements. INSERT statements are used to add rows of data to a table. Each row represents a single record in the table.
