In this chapter we learned how to establish a database connection on the local host as well as from the remote host. You should now be familiar with the Oracle Net Listener concepts and configuration. In this chapter, we have also learned about Oracle memory management and the procedure to change memory settings.
In the next chapter we will interact with the database by writing SQL queries. Some of the most commonly used SQL functions will also be discussed. We will create a sample table in the next chapter and learn to insert, modify, and delete records from this table.
