A new session of each course opens each month, allowing you to enroll whenever your busy schedule permits!
How does it work? Once a 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.
Keep in mind that the interactive discussion area for each lesson automatically closes 2 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 2 weeks plus 10 days to complete the Final and finish any remaining lessons in your course. No further extensions can be provided beyond these 10 days.
Lesson 01 - Relational Database Concepts
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 we'll talk specifically about the Structured Query Language (SQL) and the database tools you'll use throughout the course.
Lesson 02 - Creating a Database
Today you'll jump right into the course by creating the actual database you'll use in all the lessons that follow. You'll learn about the most common object in Oracle: the table. Then, I'll explain addresses the common datatypes that describe the kind of information a column in a table will store.
Lesson 03 - Users and Tables
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. We'll also discuss managing tables and how to modify their structure by altering and deleting information.
Lesson 04 - Constraints
Today, we'll put together all the pieces of the database puzzle. We'll discuss defining and managing table constraints, then you'll learn about the five integrity constraints that Oracle supports, as well as what their purposes are. I'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.
Lesson 05 - Basic SQL Statements
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.
Lesson 06 - SQL*Plus
Today 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.
Lesson 07 - Restricting and Sorting Data
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.
Lesson 08 - Inserting Records into a Table
Today, you'll go beyond the INSERT command's basics. I'll introduce you 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.
Lesson 09 - Updating Rows in a Table
In today's 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.
Lesson 10 - Displaying Data from Multiple Tables
Up to this point in the course, you've been creating queries based on a single table. Today, you're going to 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.
Lesson 11 - Creating Other Database Objects
Today, you're going to 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. In this lesson, you'll learn about other database objects and learn how to put them to use, too. Then you'll make use of the data dictionary and query some useful views.
Lesson 12 - Creating Reports in SQL*Plus
In our final lesson, you're going to learn how to format query results to generate a finished report. You'll use SQL*Plus to create reports by using SELECT statements. Then you'll modify the display of the query results to create a polished report.
