1 Self-Demo Guide Oracle ilearning and HTML DB The Oracle Academy allows a school to offer advanced Database and Java programming courses through the use of Oracle s infrastructure. The school needs no additional resources. For specific information, navigate to Click on the Participation Requirements link on the left side of the page. DIRECTIONS: 1. Begin at a computer with internet access. 2. Open a browser (preferably Internet Explorer 5.5 or higher) 3. On the left side of the Academy Homepage: click on the Student Login. This will take you to the Student Login area. 4. On the left side of the Student Login area enter the following information: Username: oracle.academy password: oracle This takes your browser to ilearning, Oracle s Learning Management System. The Academy Curriculum Demo is a small sample of the Oracle Internet Academy lesson-by-lesson curriculum.

2 Click Play 5. Click the Play button. Depending on where the last user logged off, you will be in one of the four Academy courses. Each course includes approximately 90 contact hours. There are a total of 18 sections with 5 lessons each. These modular lessons are being used in a variety of school scheduling formats. 6. Use the Outline on the left to navigate to Section 0 Road Map for Data Modeling Be sure to check out how we map to National and State Standards We provide a rich assortment of hands-on activities, assessment tools as well as various media to address different student learning styles. 7. After exploring Course 1, proceed on to Course 2 SQL, Section 1 Introduction to SQL and basic SELECT statements. Check this out!

3 8. Click on the Animation: Project and Selection. The SQL curriculum allows students to implement their data models and build a relational database using the second component of Oracle s online infrastructure, This site will allow you to access Oracle s enterprise database. Now called HTML DB 9. Click on the Project Marvel hyperlink. Once you click on the Project Marvel link (Project Marvel is now called Oracle HTML DB), you will see the login screen. NOTE: You will be logging in as a Teacher. Brief explanations are provided to illustrate what is different for a teacher and student.

4 10. Log in using the following information: School = USVA_XXX Username = USVA_XXX_SQL01_T01 Password = oracle Login Once logged in, users will see the SQL Workshop icon as shown below. Click on this icon. This is the main component used for the SQL curriculum. Workspace Username Password USVA_XXX USVA_XXX_SQL01_T01 ****** SQL Workshop Click on the Command Processor to enter SQL statements. Enter SQL queries, describe database objects, or enter any valid SQL command. View a history of previous SQL statements, or an archive of your saved SQL queries. SQL Command Processor Scripts Users can upload, create, edit, and delete SQL scripts that are stored in the Script Repository that resides in the Oracle database. Click on the Scripts icon to learn more. Data Browser Users can browse various database objects. Below is a list of these objects. Click on any of these objects to learn more about them. Click on a database object type to view objects of that type Functions Indexes Packages Procedures Sequences Synonyms Tables Triggers Views Gain instant access to an integrated online application development suite. With HTML DB you can build robust dynamic web applications and leverage the full power of the Oracle database all from your favorite browser.

5 There are 3 main sub-components used in HTML DB. SQL Command Processor SQL Command History Script Repository Browse Database Objects 11. To begin, click on the SQL Workshop tab. SQL Workshop SQL Scripts Browse 12. Next, click on the SQL icon to explore the SQL Command Processor. SQL Command Processor: The SQL Command Processor window is where users enter all SQL statements. A sample SQL SELECT statement is shown below. Schema: USVA_XXX_SQL01_T01 13 Type the following command and click on the Run SQL button to see the results. Teachers will be able to run statements in any student schema, as well as their own. Students, however, can only see data in their schema. Click on the drop down box to see all of the schemas you have privileges.

6 Enter a SQL or PL/SQL Statement (All statements are auto committed.) select last_name, first_name, salary from employees; 14. Click on the History All SQL transactions are kept in the History log in case users need to edit or re-run a particular SQL statement. The History link can be found in the menu bar on top of the SQL Command Processor window. SQL Command Processor History Archive Plan Users are also able to save a SQL statement and store it in the Archive log. Archiving a file is a good way to store statements that you may continue to work on or ones that you may run frequently. Teachers have privileges to their students History and Archive files. Notice that you can see student01 s history of SQL statements. 15. Drop down to USVA_XXX_SQL01_S01 and click Go Only teachers have this privilege. Students will only be able to see their own History. Show USVA_XXX_SQL01_T01 Go SQL Command History Created By SQL select last_name, first_name, salary from :42:08USVA_XXX_SQL01_S01 employees :25:34USVA_XXX_SQL01_S01commit

This includes access to each student s History, Archive, Script Repository, and browsing database objects. 16. Next, click on the Scripts tab to explore the Script Repository. SQL Workshop SQL Scripts Browse Script Repository: Users can run, view, edit, upload or create SQL Scripts that will be saved in the Script Repository. The Script Repository is mainly used for: SQL statements that have multi code blocks (Ex. CREATE and INSERT script) Statements that use CREATE, INSERT, UPDATE, or DELETE Repository for important scripts Lengthy code scripts Teachers have access to 17. Click on the drop down box to see students Srcipt Repository. their student s scripts. This makes for a nice and easy Show USVA_XXX_SQL01_T01 Find Go way to check homework!

This allows you to view the SQL statements within the script. Select the link that says View document as text. You will see all of the code written for this particular script. 19. To edit the SQL script, click on the paper and pencil icon. This will take you to the SQL Command Processor window where you can modify the script. Make sure to click on the Apply Changes button to make sure that the changes are saved. 20. To run the SQL script, click on the Run link found under the Actions column.

8 NOTE: All scripts that are created or uploaded into the Script Repository must end with / instead of a semicolon (;). Next, click on the Browse tab to explore database objects. SQL Workshop SQL Scripts Browse Browse Database Objects: It is not uncommon for users to want to view their tables in order to see their column definition. Schema: Type: Search: Click on the drop down box to browse other database objects such as Views, Indexes, and Sequences. USVA_XXX_SQL01_T01 Table 21. To view the meta-data, click on the magnify glass icon next to the object name. Database Object Results Click here to see the meta-data. Name StatusCreated Last DDL COUNTRIESVALID :59: :59:16 The Table Summary (or meta-data) shows all the columns and their definitions, any index, triggers, constraints, and foreign keys relating to that particular table. The Browse area also allows users to view the Data Dictionary objects. These objects contain information about the Oracle database. For example, the control files store information about the location of the datafiles in the database. You will notice that the page defaults to viewing the Table database objects. If you would like to view the other objects, click on the drop down box and select the object of your choice.

9 There are other features of HTML DB that will be explored further once your school has completed their registration and order. Our professional development has been designed to ensure that teachers are comfortable with the technical material and proficient in their use of Oracle software. This concludes the self-guided demonstration. As EARLY REGISTRATION IS ENCOURAGED, contact your local Academy Outreach Manager at at your earliest convenience.
