SQL Server database continuous integration workflow SYNC step – Creating the synchronization/migration script

In this article, the last step of SQL Server database continuous integration (CI) workflow, or the first step of a continuous delivery (CD) workflow) the Sync step.

In the previous article, the Test step described how to create and run unit tests against a database. If all tests are passed, the tested database can be compared to a final QA environment or even Production databases, and a synchronization script will be created to publish the changes.

Create daily database backups with unique names in SQL Server

Introduction

When working with a large number of databases on multiple SQL Servers, creating a foolproof disaster recovery plan can be challenging. Well organized backup and restore strategies will definitely help with this. In order to successfully implement these strategies in a larger environment, configuring automated backup and restore processes is a must. Some database administrators use the batch or power shell scripts for automation, while other prefer to use various 3rd party solutions. In both cases, it is necessary to format database backup names properly. Properly formatted backup names make the job of organizing and maintaining of the backup sets much easier. Old backup files are usually obsolete, and they can be easily identified and deleted from the drive either manually, or by using a script.

Deleting or changing objects may affect other database objects like views or procedures that depends on them and in certain instances, can “break” the depending object. An example can be that if a View queries a table and the name of that table changes. The View will no longer function.

How to maintain SQL database changes working with Git branches

In case of database development, in the same way as for the application development, there are always tasks such as developing a new feature, fixing bugs from the current release, experimenting with code in order to improve performance, usability in any way and so on. Because of all of this, it is essential that any changes that have to be committed, but not immediately, are segregated to an isolated environment, that does not affect the rest of the team or the main code. For instance, when developing a new feature, it may require a lot of changes to be committed, before the feature, or even a functional part of the feature becomes useful, so the rest of the team can apply it on their local copies of a database. Without having the isolation while developing, the team will lack the freedom to code, without having to worry about breaking the existing code base.

SQL Server database continuous integration workflow POPULATE step – Populating the newly built SQL database with data

In the third part of the continuous integration aka “CI” workflow, the Populate step will be described.

After the Build step is successfully finished, where a new database is built directly from latest changes in source control, the Populate step is initiated. In this step, non static tables in the newly built database from the source control repository will be populated with test data.

SQL Server compliance requirements

To be in compliance means to be conforming to a specific set of regulations, standards, policies or laws. Many countries worldwide have specific laws or regulations which are imposed to companies and organizations which they have to follow in order to satisfy specific standards or rules – to be and remain in compliance. Organizations that use SQL Server databases to store customer data and other information abide to the compliance requirements. Additionally, even those organizations that are not subject to compliance regulations or laws need to fulfill their own organization policies, hence they tend to introduce their own compliance regulative.
