release…
• Agile Development
• Process Automation
• DevOps

6. Why Manage Change?
80%
More than
50%
of unplanned
downtime is
due to
Change
of this, half is
due human
errors
40% of changes fail

7. Database is a Key Component
• The database holds your essential
information
• Changes can impact the entire system
• Need to be synchronized with other changes
• Often overlooked

8. The Weakest Link In a Chain
• Old adage but true
• The database is often “forgotten” and
therefore can become the weakest link
• Essential from a compliance point of view
• Should be the strongest link
• “Using NoSQL can eliminate the step of data migrations and
schema changes, often manual steps or exceptions to a continuous
delivery workflow” http://en.wikipedia.org/wiki/Continuous_delivery
(Rarely a practical option…)

9. Reaching Inside the Database
• There is more to a database than SQL scripts
•
•
•
•
•
Schema structure
Code
Content and meta-content
Internal dependencies
…
• Ensure that changes are not made without
authorization
• Ensure no out-of-process changes

10. Poll – What do you utilize
• Which Method your organization utilize?
• Application Version Control
• Database Version Control
• Application Lifecycle Management
• Agile
• DevOps

11. What is DBmaestro TeamWork
• Database Enforced Change Management
•
•
•
•
Database version control
Plugs into the ALM (change request, tickets & work items)
Database change impact analysis
Database deployment automation
• DevOps Solution for databases
• Deployment, rollback & recovery
• Plugs into release management

12. Two isolated Processes
Development Process
Version Control Process
(file based)
Check-Out

Check-In
Script

Modify Script

13. Database deployment automation
• Major challenge…
• Risky if done incorrectly…
• Conflicts & Merges
• Code overrides
• Outdated update scripts
• Need Impact analysis processes
• Traceability and transparency
• Audit and compliance
• Automating problems into production is a major
risk!!!

Thousand Words…

16. Poll – Level of automation
• How much do you automate your database
deployment?
• None, script is written manually
• Generating script automatically, review
manually
• Internally within development
• Development -> QA
• Development -> QA -> Pre prod
16

17. Database Deployment Methods
• Build Once Deploy Many
•
•
•
•
Execute same script across all environments
Saved in file-based version control
Check-In is done before change being tested
Not aware to changes made out of process
• Build & Deploy On Demand (best practice)
•
•
•
•
Aware of out of process changes
Handles the same script challenges
Alerts on conflicts between environments
Up-to-date script
