How to Enable Risk-Free

Database Experiments

Kyle Hailey & James Murtagh

Tradeoff: Speed, Quality, Cost

Good, Cheap, Fast : choose two

Fast

Good Cheap

What We’ve Seen

1. Inefficient QA: Higher costs of QA 2. QA Delays : Greater re-work of code 3. Sharing DB Environments : Bottlenecks 4. Using DB Subsets: More bugs in Prod 5. Slow Environment Builds: Delays

1. Inefficient QA: Long Build times

Software Engineering Economics – Barry Boehm (1981)

3. Full Copy Shared : Bottlenecks

Frustration Waiting

Old Unrepresentative Data

4. Subsets : cause bugs

3. Subsets : cause bugs

Classic problem is that queries that run fast on subsets hit the wall in production. Developers are unable to test against all data

The Production ‘Wall’

DEPLOY OFTEN, REDUCE ERRORS

Source control reduces deployment errors

• See who changed what, why and when

• Gives context to the development of the db

• Collate changes in sandboxed development

Best practices

• Develop in a sandboxed environment (not usually an issue for app development)

• Get latest often (and test changes) – before checking in

• Check in often – small logical units

• Check in messages should be descriptive

Reducing errors at deployment

• Deploy changes from source control

• Compare source and target schemas before deploying changes

No need to write update scripts by hand

Benefits of Red Gate tools – shared development db

SVN /

TFS Dev Test UAT, Production etc.

• Removes manual processes to checking in changes to source control • Lock objects on a shared development database while you work on them • Fast and accurate comparison of environments (compare source control to the database) • Generate update scripts to deploy changes accurately

Live Demo

• Delphix: Create 3 Virtual Databases

1. Dev1

2. Dev2

3. Trunk

• Have 2 Developers

– Developer 1 modifies “Dev1” and source controls changes

– Developer 2 modifies “Dev2” and source controls changes

• Red Gate Schema Compare for Oracle Merges:

– “Dev1” changes into “Trunk”

– “Dev2” changes into “Trunk”
