Java Training Overview
This one-day course covers the fundamentals of database programming in Java using JDBC (Java Database connectivity) in an incremental fashion, to get the programmer up to speed quickly and then to layer a deeper understanding of JDBC upon that foundation. This course has been designed to work with any of these relational database management systems:
- Apache Derby, version 10.1
- MySQL, version 4.1
- PostgreSQL 8.0
- Oracle, version 9i or 10g
Lab exercises use SQL99 constructs whenever possible in order to be relevant to databases from all vendors. The course software also includes an optional overlay of workspace and project files to support use of the Eclipse IDE in the classroom. (This requires that the instructor be experienced in use of Eclipse and able to walk students through basic tasks in the IDE.)
This revision of the course targets the 1.4.2 version of the Java language and Core API, though the impact of choosing a 1.4.x or 5.0 Java environment is minimal for this level of JDBC study. For training targeted to the 5.0 environment, please see version 5.0 of this course
Java Training Prerequisites
- Experience in Java Programming is essential. The student must be comfortable with object-oriented Java, interfaces and abstract classes. “Java Programming,” is excellent preparation.
- Understanding of basic SQL usage or other work with relational databases will be helpful, but is not required.
Java Training Learning Objectives
This course will teach you to:
- Briefly review relational database fundamentals with an awareness of the differences between SQL99 and SQL implementations by database vendors.
- Connect to a database using JDBC and perform a simple query.
- Update relational data using JDBC to execute updates, inserts and deletes.
- Use prepared statements to produce reusable database queries and optimize execution time.
- Use callable statements to access database procedures.
- Use scrollable and updatable results sets for more robust solutions.
- Use commit, rollback, and savepoint to build transactional systems.
- Use batch processing for efficient handling of large datasets.
- Understand the use of RowSets and the improved techniques and portability that they bring to JDBC.

Hardware/Software Requirements
Hadware
- Pentium 500 MHz, 256 MB RAM, 500 MB disk.
- Pentium 1.5 GHz, 512 MB RAM, 1 GB disk. For Oracle systems, significantly better processing power and memory is recommended – see Oracle’s own documentation for this.
Software Requirements
- All free downloadable tools, with an option to use certain commercial products. The course supports the following database software:
- Apache Derby 10.1 (formerly Cloudscape) – this product is included with the course software and is the default
- MySQL 4.1 – this is a free downloadable and the Connector/J driver is included with the course software
- PostgreSQL 8.0 – this is a free downloadable and the JDBC driver is included with the course software
- Oracle 9i or 10g – no license or software is included with the course
Operating system
- Tested on Windows 2000 and XP Professional editions. The course software should be viable on all Windows or Linux systems that support J2SE 5.0.
