About DBmaestro…

Agenda

• Yesterday, Today & Tomorrow• App development vs. DB development• Exploring the gap• Short demo• Benefits

Yesterday, Today & Tomorrow

Yesterday – Version Control

• Version Control becomes standard de-facto• Files are Checked-Out & Checked-In to

reflect the change• All changes are documented• Ability to tag a version crossing different revisions• Ability to compare changes across the history• Know Who did What, When and Where

Yesterday – ALM

• Application Lifecycle Management not only:• Version Control• Test Management

• Application Lifecycle Management consists of:• Requirement Management• Version Control• Change Management• Test Management• Release Management

Today – Agile

• Adopted quickly by many organizations• Allows development teams to present working

products every couple of weeks

Tomorrow – DevOps

• Agile already adopted quickly by many organization• Collaborate development teams and operations to

ensure highest quality deployments

“Every developer must think of the end user. Committing a piece of code is far from being done. It needs to work in all kinds of weird use cases. And it’s not only QA’s job to find all the bugs. Good developers want to ensure that the new features are not only coded, but tested and ultimately

released to their users. Only then the task is really done.” Matthias Marschall

Poll – What do you utilize

• Which method does your organization utilize?• Application Version Control • Database Version Control• Application Lifecycle Management• Agile• DevOps

Methods & Processes Evolution

Version ControlKeep Track of Changes

ALMLink the Change to the Reason

AgileQuick Development of Small Requirements

DevOps

High Quality & Quick Deployment of Development Products

App development vs. DB development

Poll – Database Version Control

• What is the main feature you see in database version control?• Working directly in the Oracle IDE

(required to Check-Out the object)• No need to maintain change scripts• Generating the deployment scripts• Integration with Change Management System (ALM)• Merge & Deploy automation

One enforced process

App Development

Check-Out File

Modify File

Run Applications’

Tests

Check-In File

DB Development – Today

Two isolated processes

Benefits We Do NOT Have

Visibility into the Lifecycle of Releases

Concurrent Database Development

Consistent Database Environments

Meeting Release Schedules with Desired Quality

Automated Tasks

Agility in Responding to Scope Changes

App & DB GAP

App Development

Version Control: App vs. DB

Text Based

DB Development

Knowledge of the content change is not relevant

No relationship between files

Store locally

Changes published only in Check-In

Deploy done by copy & replace previous executable

Many types of objects and syntax

Reference data has many formats

Central resource

No Change Policy Enforcement

Changes affect immediately

Deploy must preserve existing data

One enforced process as exists in App Development

DB Development – The Future

18

Poll – Oracle IDE

• Which Oracle IDE do you use?• Oracle SQL Developer• Oracle PL/SQL Developer• TOAD• SQL Navigator• SQL*Plus

19

Database & Version Control

• Same Version Control Principles:

Object LockingCheck out / in for PL/SQL Code, Structure & DataBaselineTag / Label / Golden CopyCompare / MergeDeploy / Build

20

Database & ALM

• Integration with Change Management System

Know the Reason (Why) for any changeAbility to Deploy changes by TasksBetter reports on the work for each Requirement

21

Database & Agile

• More then just Compare & Sync• Merge Changes from several environments

Automation (web services, command line)Deploy based on Version Control Repository3-Way analysis

22

Baseline in Deployments

23

Simple Compare & Sync 3-way Analysis & Deploy

With Baseline the unknown is now known

You do not have all the information

DevOps Deployment

• Many small deployments deployed frequentlyGenerate on-the-fly deploy scripts3-Way Analysis – prevents wrong decisions

• Application Deployment• Copy & Replace• Error Recovery – Replace new binary,

fixed quickly• Database Deployment

• Alter objects• Error Recovery – New deploy script,

long down time

24

Benefits - Development

• Database Change Repository• Follow SCM best practices

(Check-Out/Check-In)• All Changes are documented• Manage Who can do What, Where, When & Why

25

Benefits - Operation

• Integrated Deployment Engine• Business Level Audit• Roles & Responsibilities Enforcement

26

Summary

• Implement ALM, Agile & DevOps methods in database development

• Manage Who can do What, Where, When and Why• Build Safety net to reduce issues in production
