1. Bringing DevOps to the Database

DevOps is a hot topic in today’s software development world. However most of the knowledge and experience with DevOps is based around application software and ignores the database. We will examine how the concepts and principles of DevOps can be applied to database development by looking at both automated comparison analysis as well as migration script management. Automated building, testing, and deployment of database changes will be shown.

4. The Database Development Pipeline
Create table Orders
( OrderID int
, OrderDate datetime
, salesrep int
, customerid int
, status tnyint )
Dev
Create procedure GetOrders
@o datetime As
Begin
Select *
from orders
Where orderdate
using System;
using System.Collections.Generic;
using System.Text;
using eBay.Service.Core.Sdk;
using eBay.Service.Core.Soap;
namespace Trading_Samples {
    class Program
    {
        static void Main(string[] args)
        {
            MakeGetOrders();
            Console.ReadLine();
Developers write code, working with test systems.

5. The Database Development Pipeline
Create table Orders
( OrderID int
, OrderDate datetime
, salesrep int
, customerid int
, status tnyint )
Dev
Create procedure GetOrders
@o datetime As
Begin
Select *
from orders
Where orderdate
using System;
using System.Collections.Generic;
using System.Text;
using eBay.Service.Core.Sdk;
using eBay.Service.Core.Soap;
namespace Trading_Samples {
    class Program
    {
        static void Main(string[] args)
        {
            MakeGetOrders();
            Console.ReadLine();
Application code usually goes to a VCS

6. The Database Development Pipeline
Continuous Integration
Create table Orders
( OrderID int
, OrderDate datetime
, salesrep int
, customerid int
, status tnyint )
Dev
Create procedure GetOrders
@o datetime As
Begin
Select *

Where orderdate
using System;
using System.Collections.Generic;
using System.Text;
using eBay.Service.Core.Sdk;
using eBay.Service.Core.Soap;
namespace Trading_Samples {
    class Program
    {
        static void Main(string[] args)
        {
            MakeGetOrders();
            Console.ReadLine();
Here the application usually kicks off a CI process

25. Summary Understand and implement the DevOps principles
Systems Thinking
Feedback Loops
Experimentation and Learning
Treat the database like application code
Build the exceptions into your process
Adapt to your environment
Do more of what works
Do less of what doesn’t
