Oracle DBA (Database Administrator) Tutorials
In this Oracle DBA Tutorials For Beginners and Professionals series, we covered all the concepts of Oracle DBA with Real-Time Examples. You will learn from the very basic to the advanced level features of Oracle DBA (Database Administrator) as you progress in this Course.
Hello and welcome to this Oracle Database Administration Tutorials Course. These Oracle DBA Tutorials will take you through most of the practical applications of Database Administration.
Oracle is one of the main database tools that is used in the job market, and the ability to being able to do DBA for Oracle could be very useful for your current work, and your next job hunt.
How do we Design this Oracle DBA Course?
In this course, we will start with the introduction to Oracle Database and we will show you the different editions of Oracle and which edition we are going to use. We’ll also show you how to download and install Oracle Database for free. We’ll start by creating a demonstration database, learning how to backup and restore the database, and what recovery models are appropriate for other databases, to enable you to offer Point in Time recovery.
We’ll manage logins and server roles, so you can control who gets access to what data, implement and maintain indexes, so you can speed up searches, and import and export data. We’ll look at managing and configuring databases, and look at compression, both of which aid with administrating big databases. And much more.
The course is fairly relaxed – there will be a few “wrong turns”, so you can see what problems might arise, but every lesson works towards an end goal at a relatively slow pace, so you can follow on your own computer easily. I assume that you know how to use a computer, including installing programs, but the actual DBA will be at a basic level, and I’ll introduce every component as we go on.
