Project Hosting on Google Code is a web-based platform for open source development, providing mailing lists, an issue tracker, a source code repository, download areas, and so on. This talk will focus on a new version-control component of Project Hosting on Google Code: Mercurial backed by Bigtable. Mercurial/Bigtable is designed to scale over thousands of machines and use Bigtable’s replication to run over multiple datacenters. It is built to be able to host hundreds of thousands of open source projects. Come learn about Mercurial’s architecture, and how we’ve extended it to grow to “Google size”.

MySQL Replication – Audit, Test & Verify

Published February 5th, 2009 Under Configuration Management | Leave a Comment

MySQL replication is fairly easy to set up, but in the real world many obstacles can get in the way of keeping it up and running smoothly. One problem is the slaves getting out of sync with the master. If you’re lucky you’d be alerted with an error in your slave log file, and can then track down that problem. But sometimes it drifts out of sync silently. Both are situations you want to avoid. Sean Hull talks about why this happens, both in terms of things that happen in the  application and in MySQL’s implementation of statement-based replication. Then he shares a method to eliminate the problem by testing and verifying your current setup.

Effective Test Driven Database Development

Published November 24th, 2008 Under Uncategorized | Leave a Comment

Although test-driven development is now considered common sense in the OO world, it is very rare in database development. This session looks at the reasons behind that and presents solutions and best practices for test-driven database development. Database testing is analysed from two aspects: unit-testing in the database (stored procedures,views) and integration testing from the object service/web layer down to the database. This session is aimed at database developers,technical architects and Java/.NET developers working on enterprise applications. In this talk, Gojko Adzic look at why test-driven development is rarely used in database development. He will discuss the reasons behind this and present solutions and best-practises for test-driven database development.

Agile Database Techniques: Data Doesn’t Have To Be A Four-Letter Word Anymore

Published March 3rd, 2008 Under Uncategorized | Leave a Comment

Data is clearly an important aspect of software-based systems, a fact that the information technology (IT) industry has understood for decades, yet many agile development teams are struggling to involve data professionals within their projects. The Agile Data (AD) methodology defines a philosophical framework for data-oriented activities within agile projects, defining ways that application developers and data professionals can work together effectively. However, philosophy isn’t enough, you also need proven techniques which support those philosophies. In this presentation Scott Ambler discusses techniques for agile database development, including: database refactoring, Agile-Model Driven Development (AMDD), Test-Driven Design (TDD), and environment/tool strategies.
