To achieve gains from Database Lifecycle Management in general, and in Continuous Deployment in particular, it pays to aim for lightweight but consistent techniques and processes, refining them iteratively in the light of experience. Edward Elliott describes a Test-driven development process for developing SQL Server databases that worked for CD, based on a series of steps. Though the tools for CD may be necessary, they are not sufficient, without an effective structured process.… Read more
Database Lifecycle Management aims to make the development and modification of databases more predictable. Bugs are the source of more unpredictability than anything else, purely because it is so difficult to guess how long it will take to fix them. Good testing at all stages may take some time and effort, but it greatly reduces likelihood of the wildcard factor of the bug that is first detected during the deployment process; or worse, that gets into the production release.… Read more
Although the techniques of Database Lifecycle Management can reduce the timescales for the delivery of new functionality to business systems, what if the database 'layer' consists of several large interdependent databases and data flows with replication and audit? Does DLM scale to this level of complexity? Margaret Cruise O'Brien starts a series of articles that describes the practicalities of improving DLM within an existing framework and team supporting a multi-database multi-server system, by describing some of the database management problems and solutions in an enterprise-scale database.

Database Lifecycle Management (DLM) aims to provide a roadmap of what is required, and when, to deliver and maintain effective databases that can respond quickly to business change. How does the DevOps movement, as it applies to databases, fit into this? William Brewer explains how DevOps provides the organisational change between delivery and operations to make important parts of the process easier to introduce.… Read more
The latest versions of Team Foundation Server are not only sophisticated, but extensible. Continue their course of openness, Microsoft have opened up TFS, and are making it possible to build custom systems on top of it. Karsten Kempe points out three new features that make it possible to build an ALM system to exactly suit you needs, using TFS as the underlying platform, and demonstrates what's possible with an open source dashboard and work-tracking system.… Read more
In order to automate the delivery of an application together with its database, you probably just need the extra database tools that allow you to continue with your current source control system and release management system by integrating the database into it. If you're using the Microsoft stack, then Redgate's tools can help with some of the difficult database parts of the process, as Jason demonstrates.… Read more
