1. Quick review of SQL And conversion to Oracle SQL

2. Assuming… You know how to model data using –An ER diagram –A class diagram You know how to translate entity- relationship models into: –Tables –With constraints

3. SQL Structured Query Language Made up of the following components: –Data Manipulation Language (DML) –Data Definition Language (DDL) –Transaction control –Data Control Language (DCL) Oracle SQL complies with the core ANSI/ISO standard for SQL:2003, but is not completely compliant. It also has extensions, that are not compliant, so are not portable to non-Oracle databases.

4. DML SELECT INSERT UPDATE DELETE

5. DDL CREATE ALTER DROP –Any object in the database. TRUNCATE –Deletes all rows in a table.

6. Transaction control A database transaction is a unit of work that leaves the database in a consistent state. To ensure consistency, ongoing work can be committed, rolled back to a checkpoint, or rolled back completely. COMMIT ROLLBACK

7. Data Control Language These control user access to an Oracle database. These instructions include: –GRANT –REVOKE –SET ROLE…
