Database Development: The Object-oriented and Test-driven Way
Slideshow
As developers, we've created heuristics that help us build robust systems and employed test-driven development (TDD) to improve code design and counter instability. Yet object-oriented development principles and TDD have failed to gain traction in the database world. That’s because database development involves an additional driving force-the data. Max Guernsey shows how to treat databases as objects with classes of their own-rather than as containers of objects-and how to drive database designs from tests. He illustrates a way to give these database classes the ability to upgrade old data without introducing undue risk. Max also shares how to apply good object-oriented design principles to database classes and how to enforce semantic connections between databases and clients.

Lipstick on a Pig - How Illusion Leads to Crisis in Real World Projects Change, ambiguity, and risk are key issues whether you are running a software project, managing a development team, or leading an entire organization. We learn it over and over again. It's not a matter of "if" change will happen-it's a matter of "when." When a crisis inevitably arrives, how do you respond? As Jerry Weinberg observed in The Secrets of Consulting, "It may look like a crisis, but it's only the end of an illusion." Andy Kaufman looks at key project illusions that threaten success as we lead projects and people in the realm of software development. Whether you're a project team member or a senior executive, Andy provides practical tips you can immediately apply in your organization.

The QA/Testing Perspective on Software Security Most everyone now realizes that we cannot solve security vulnerabilities with firewalls, virus scanners, and other tactics that build an electronic “moat” around systems. According to Julian Harty, security is not an operational issue, not a developer issue, and not a testing issue. It is a systems issue that you must focus on throughout the software’s life. From a QA/testing perspective, we need to look early in the development process for adequate security requirements. Then, we should assess the designs for vulnerabilities and participate in security code reviews. When specialized, security tests find bugs that get past our early prevention efforts, causal analysis helps prevent the recurring security defects. Dig into system security issues with Julian and learn about manual techniques, commercial software, and home-brew automation tools to help you find security vulnerabilities-before the bad guys do.
