Program Changes
• Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
• connection = DriverManager.getConnection("jdbc:odbc:customer",“id",“password");
JDBC
• DriverManager Class• Class manages JDBC drivers and provides uniform interface
for establishing connections to databases• Load the driver by calling : Class.forName(driverClassName);
Class.forName(“sun.jdbc.odbc.JdbcOdbcDriver”);
• If the driver can’t be loaded, a ClassNotFoundException is thrown.
Presentation Guidelines
• Objectives• Preparation• Delivery• Make presentation interesting!
Objective(s)
• Consider:• What are the objectives? • What are the main points you want to make?
• Have clear outcomes or results that you are want to achieve.• State up front what it is you are trying to achieve.
• If you don't say the one thing you need to say up front, it may never get heard.
Suggestions to structure a presentation• Conclusion/main point first! • Project Background
• Justifications, your product and development, and anything that shows how you dealt with issues
• Conclusion — Repeat the main point
Delivery
• Convince us!
• Discuss problems/issues.
• Audience interaction is important • Use creativity to make presentation meaningful
• PowerPoint is not a requirement
• Code is not typically appropriate
• Never read from a script.
• Move around. Don't stay behind a podium• Get into a place where you can see the screen as
well as the audience. • Stand to the left of the screen. People read left to
right. • They should start with you and move to the screen.
• Audiences want entertainment, enlightenment and education.
Make presentation interesting• Use graphics, handouts, etc.
• Use good color contrast• Use large enough fonts so that back row can
see your presentation• Present the material in a novel manner.
• Keep to the time allowed. • As a rule of thumb, allow 2 minutes for each
slide
• At the end of your presentation ask if there are any questions
• Don't run over! Ever!
