In this lesson, you'll gain a solid understanding of terms and concepts surrounding a relational database. You'll learn what's involved in the planning of a database and the steps involved in designing a database. Then you'll learn specifically about the Structured Query Language (SQL) and the database tools you'll use throughout the course.
In this lesson, you'll jump right in and create the actual database that you'll use in all the lessons that follow. You'll learn about the most common object in Oracle: the table. Afterwards, you'll learn the common datatypes that describe the kind of information a column in a table will store.
In this lesson, you'll learn about database users and you'll even have an opportunity to create a user of your very own. This lesson will not only provide you with a crash course in SQL*Plus, but it will also help you create all the tables you'll need for your database. The lesson will discuss managing tables and how to modify their structure by altering and deleting information.
In this lesson, you'll put together all the pieces of the database puzzle. The lesson will discuss defining and managing table constraints and teach you about the five integrity constraints that Oracle supports, as well as what their purposes are. It'll show you how to define integrity constraints during table creation with the CREATE TABLE statement and after a table have been created with the ALTER TABLE statement. With this information, you'll create the primary and foreign keys for your database's tables.
You'll gain considerably more knowledge about the Structured Query Language in this lesson, where you'll be introduced to two new commands—the INSERT and SELECT commands. Then, you'll execute the commands to insert rows of data into the tables and query the data you inserted.
In this lesson, you'll gain experience with additional SQL*Plus know-how. You'll learn how to correct errors and manipulate lines in the SQL buffer. Then, you'll understand additional syntax of the SELECT statement.
In this lesson, you're going to learn more about the SELECT command, the most commonly used SQL statement. The SELECT command allows you to query the data in a database. You'll find that you need to be familiar with the data in your database, and that queries provide you with means to view what's stored in your tables.
In this lesson, you'll go beyond the INSERT command's basics. You'll be introduced to more advanced features of the INSERT command, then you'll learn the different methods of inserting rows of data and apply those skills to load data into your tables. You'll also learn some troubleshooting techniques to perform when Oracle returns an error message during an INSERT command.
In this lesson, you're going to learn how to modify data in the database's tables using the UPDATE command. You'll learn how to manipulate the data in your tables by updating the values in the columns and by deleting rows of data. You'll learn how to make those changes permanent with the COMMIT command, as well as how to undo a change with the ROLLBACK command.
Up to this point in the course, you've been creating queries based on a single table. In this lesson, you'll learn how to display data from multiple tables. You'll learn how to utilize your working knowledge of the SELECT statement and explore the world of joins.
In this lesson, you'll learn more about common database objects and their uses. At this point, you'll have gained considerable knowledge of the most common database object—the table. You'll also learn about other database objects and learn how to put them to use, too. Finally, you'll make use of the data dictionary and query some useful views.
In the final lesson, you'll learn how to format query results to generate a finished report. You'll use SQL*Plus to create reports by using SELECT statements, then modify the display of the query results to create a polished report.

There are no prerequisites to take this course.
The instructional materials required for this course are included in enrollment and will be available online.
A new session of each course opens each month, allowing you to enroll whenever your busy schedule permits.
Once a course session starts, two lessons will be released each week for the six-week duration of your course. You will have access to all previously released lessons until the course ends.
The interactive discussion area for each lesson automatically closes two weeks after each lesson is released, so you're encouraged to complete each lesson within two weeks of its release.
The final exam will be released on the same day as the last lesson. Once the final exam has been released, you will have two weeks plus 10 days (24 days total) to complete the final and finish any remaining lessons in your course. No further extensions can be provided beyond these 10 days.
Great introduction course. And C. Delia's method and style was great as well. It was just what I was looking for."
I enjoyed the course although I was not able to dedicate as much time to the lessons as I would have liked to. I downloaded/printed the lessons and will use them in the future to continue to enhance my Oracle skills. We are using PL/SQL at work to write reports and create portals for our customers."
I found this course to provide just the right increments of learning a totally new (to me) subject. The examples, writing style and exercises were just plain perfect! Thank YOU!"
I would feel comfortable administering Oracle databases."
Thank you Ms Delia, I have firm grasp of what once was a confusing subject."
This is my first attempt at an online course, and I found it and the subject matter to be most rewarding. I look forward to the next session."
This was my first experience with an on-line course. The format, documentation and interaction made it interesting, informative and I'm sure I'll be referring back to my notes often."
This was my first on-line class and it was GREAT!. I enjoyed the class, and the length of the class was just right too. The materials provided by the teacher were very hepful/useful. I definitely will recommend this class to my peers."
I just wanted to thank you. I found the course more involved than I had anticipated and was quite pleasantly surprised at the level of training and the content."
