SQL Server management, tutorials, scripts, coding, programming and tips for database administrators
Microsoft HDInsight is the cloud service that deploys and provisions Hadoop clusters on the Azure cloud. It's a completely managed, open source analytics service to support enterprise needs and supports a wide variety of scenarios with the help of open source frameworks like Hadoop, Storm, Spark, R Server and Hive.

Microsoft currently offers two built-in methods of running production SQL Server databases in Azure. The first relies on the ability of Infrastructure-as-a-Service (IaaS) Azure virtual machines to host a variety of on-premises workloads, including SQL Server instances. The second one leverages Platform-as-a-Service (PaaS)-based Azure SQL Database. With the introduction of the Azure SQL Managed Instance service, you have a third option, which combines the benefits of its two predecessors.
Greg Larsen shows you a quick trick to programmatically script a way to identify when SQL Server was last started.
By looking at a query execution plan, you can determine which steps are used to resolve the query. But what if you just want to find out what the query plans are for only the queries that are currently running?
The Query Store captures a history of queries, execution plans, and runtime statistics, which persist within SQL Server and can be reviewed later. Read on to learn more.
Azure Cosmos DB offers features that facilitate data availability and resiliency. However, there is also a different, very important aspect of facilitating access to distributed data sources in the most optimal manner, which focuses on access control mechanisms. Read on to learn the specifics of this aspect, as it applies to Azure Cosmos DB.
Once you enable your database to be encrypted with Transparent Data Encryption (TDE), the physical database files, and the database backups are encrypted. If your database and database backup are encrypted, then how can you send the encrypted backup to a person outside your organization?
When using Transparent Data Encryption, you might wonder “What is the state of my transparent data encrypted database?” Read on to learn the many different states that a transparent data encrypted database might go through.
The key challenge for application developers is to build a foolproof system to ensure data security. This is not only more intense, but more complex these days, as many organizations are planning to move their applications to the cloud. Read on to learn more.
One of the most important design decisions that must be made when planning deployment of Azure Cosmos DB involves logical partitioning of data that will populate target collections, graphs, or tables. Selecting the optimal partitioning model has both performance and pricing implications. In this article, we will explore the rationale behind these implications and review the partitioning options.
By default, SQL Server does not encrypt data in a SQL Server database in an encrypted format. When SQL Server 2008 was introduced, Microsoft implemented Transparent Data Encryption (TDE). When TDE is enabled on a database SQL Server will encrypt the database as data is written to the disk. Read on to learn more...
If you have a database backup of a Transparent Data Encryption (TDE) enabled database, the database backup will contain encrypted data. Because the database backup contains encrypted data you can’t just restore it to any instance. You can only restore the database backup to an instance that contains the same certificate used to originally encrypt the database.
Anoop Kumar shows you the SQL Commands (T-SQL) to secure PII/PHI data using the SQL Server Dynamic Data Masking (DDM) feature and explores DDM's built in functions to mask all critical data elements. DDM restricts unauthorized users from accessing critical data with no changes in the application.
The majority of traditional database management systems are responsible for making sure that any changes to their data are consistently reflected in the results of subsequent queries. Azure Cosmos DB extends the range of consistency options by providing support for bounded-staleness, session, and consistent prefix models.
When you install a SQL Server instance you have the opportunity to identify the default location for your instance database backups. Overtime you might decide you want to change the default location for database backups. This tip shows you two different ways to change the default location for your database backups.
