Risks of not Having a DCM
 Lack of Visibility into the Lifecycle of Releases
 Problems with Concurrent Database Development
 Inconsistent Database Environments
 Little or No Capability for Automated Tasks
 Meeting Release Schedules with Desired Quality
 Less Agility in Responding to Scope Changes

Version Control Concepts
 Structure of repository & gained functionality
 File based
 Separation of Working
environment and repository
 File Locking
 Check out / in
 Baseline
 Tag / Label
 Head / Latest
 Rollback
 Compare / Merge
 Deploy / Build

SCM Concepts in the database world
 Traditional SCM concept doesn’t fit the Database
world…
 A database is not a collection of files
 DDL (Data Definition Language)
 DML (Data Manipulation Language)
 DDL extraction
 No debug environment
 Content ?
 Database duplication – constant synchronization

SCM Concepts in the database world
 Moving changes…
 Development to QA, integration and production
 Code – simple file copy & registration
 DB objects cant just be “moved” – content…
 What do we do with db content changes ?

 So the whole thing was neglected for years...

 Manual process where created to deal with
real life situations
