Applying SQL Transformations and Handling Missing Values in Azure ML

Total: 1 Average: 5

In this article, we will introduce SQL transformations in action. We will also see how to handle missing values in our dataset.

Consider a scenario of a movie rating dataset containing records of different movies along with the average user ratings associated with each movie. The ratings are in numeric form ranging from 1 to 10 with 1 as the lowest rating and, respectively, 10 as the highest rating (though no movie in the history has achieved 10 rating:). Suppose that we want to convert the numeric ratings into categorical ratings. For instance, we want to replace ratings of 1-3 with the categorical value “poor”, of 4-6 with “average” while ratings of 7-10 will have the value “good”. We can accomplish it with SQL transformation in Azure ML Studio. Read More

How to Test Azure Web Application Performance through Microsoft Azure and Visual Studio

Total: 27 Average: 4.2

Before deploying your application into production, doing a performance load test is imperative for measuring future performance and ensure that your application is production-ready.

Testing is essential for every application to make sure that any application works and performs according to the desired requirements. During the application testing process, we can attempt and find out if any imperfections are remaining in the application. There are numerous sorts of testing like functional testing, unit testing, acceptance testing, and integration testing. We compose Functional and UI tests to see whether the application is working as per the requirements. Read More

Migrating SQL Server Database to Azure SQL (PaaS)

Total: 9 Average: 4.4

In this article, we will highlight SQL Server Data migration to Azure SQL (PaaS).  You can find different approaches for this migration process because SQL Server offers different types of tools and features for this migration. Some of these are:

These migration approaches have some pros and cons. But if you ask my opinion, Data Migration Assistant is better than others because, in this migration process, you will face fewer migration problems or issues. Data Migration Assistant will be more helpful to handle these issues.

In this article, we will specifically mention Database Migration Assistant, also known as DMA. At the same time, we will make a small demo of SQL Server Management Studio Deployment Wizard.

Choosing Azure SQL Purchase Model and Service Tier

Total: 7 Average: 3.9

When we are beginning to think of migrating our on-premises databases to Azure SQL, we have to decide on a proper purchase model, a service tier, and a performance level. Before starting the Azure SQL migration process, we have to find logical and provable answers to the following questions:

  • Which purchase model is suitable for my apps and business requirements?
  • How much budget do I need?
  • Which performance level meets my requirements?
  • Can I achieve the acceptable performance of my apps?

Configuring Azure SQL Long-term Backup Retention

Total: 5 Average: 3.4

Backup is the most important case for database administration because it provides business continuity solutions for high availability and disaster recovery. For this reason, Azure SQL database (PaaS: platform as a service) can make a backup automatically and restore it at a point in time. However, the retention period of backup files changes according to the service tiers.

Azure SQL Geo-Replication and Failover Groups

Total: 1 Average: 5

Azure SQL offers different types of business continuity solutions. One of these solutions is Geo-Replication that provides an asynchronous database copy. You can store this copy in the same or different data center locations (regions).  There can be four readable database copies. In the documentation of Microsoft notes, the recovery point objective (RPO is the maximum acceptable amount of data loss measured in time) is less than 5 seconds.  If we want to automate and make (users will not affect) failover mechanism transparent, we have to create the auto-failover group.
