Overview of SQL Server Features

Did you know that companies prefer SQL to plenty of reliable features available in the budget? SQL server has great features that include visualization on mobiles and the ability to track and change performance levels that can save time and money. SQL 2019 has become powerful with its new features. There is a great future scope for the experts in SQL Server DBA. So, attending SQL Server DBA training will make your career advancements. In this post, let us learn about the features of SQL Server that make SQL Server more powerful.

What is SQL Server?

SQL is a Structured Query Language that is used to operate databases. It allows us to access the data and manipulate it in the databases. We can also create, modify, delete and retrieve data from the database when requested by a software application that was run either on the same system or another system across the network. SQL Server uses SQL as the standard language for relational database management systems such as MS Access, MySQL, Sybase, Oracle, Postgre, Sybase, and Informix. 

SQL Server is implemented from RDBMS specifications and developed by Microsoft. It is platform-dependent and both command-based and GUI-based software. SQL Server supports SQL language that is non-procedural, case sensitive, and common database language. SQL Server is used to create and maintain databases. We can analyze the data by SSAS (SQL Server Analysis Services), can generate reports by SSRS (SQL Server Reporting Services), and can carry out the ETL operations by SSIS (SQL Server Integration Services). SQL Server has a client-server architecture, so it supports workstations and servers. Workstations are the interface for interacting with Server components. So a workstation component is installed in every SQL server operator’s machine. Servers are the services, so these components are installed only in centralized servers. Database administration of SQL server will help us to maintain and optimize the performance of the server while guaranteeing its availability and readability. SQL Server Database Administrator manages SQL server for accessing, storing, and organizing data. He will analyze the organization’s data input, security needs, data management and helps in developing tools for supporting information security and data access. 

Why SQL?

  • SQL enables us to access, describe, define, manipulate data. 
  • Users can even create and drop tables and databases, create functions, views, and stored procedures in the database using SQL. 
  • Users also can set permissions on views, procedures, and tables using SQL. 
  • Using SQL libraries, modules, and precompilers, SQL embeds with other languages. 

SQL Server Features:

  • Big data Clusters:

This feature enables us to deploy various scalable SQL server clusters, HDFS containers on Kubernetes, Spark at the same time. Big data clusters will allow these clusters to run simultaneously. From Transact SQL to Spark, you can process, read and write big data. It also allows us to easily analyze and combine high-volume big data with high-value relational data.

  • Intelligent Query Processing:

It is a method used to achieve an optimal query execution plan with a shorter compilation time. There are many factors that are to be considered while executing Intelligent Query Processing, mainly for generating a good execution plan like joins that are to be made in query, outer input, structures to be used, execution modes, etc. IQP features are available in SQL Server 2017 version, but in 2019, the SQL server version includes some improvements related to IQP.

  • Resumable Online Index Create:

Instead of starting the process from the beginning, the resumable online Index creates feature will allow an index to create a pause operation and restart it later from the point where the operation is paused or failed. It is a powerful tool in database management. In many database operations such as update, insert and delete, the Index will become more fragmented and therefore less effective. To counter this, the index rebuild operations are adopted by Database administrators increasingly.

  • UTF-8 Support:

UTF-8 data encoding system that is well known is supported by the new SQL server 2019. UTF-8 character encoding is used for data import, export, column level, and database-level collation. It is activated when creating or updating the object collation type as an object collation with UTF-8. It is supported for varchar and char data types. Data has to be encoded when retrieving or storing the data to reduce the storage space and provide security to sensitive data.

  • Enhanced Security:

As the SQL server is dealing with the management of the database, the security of data and transaction is a very important requirement. So there is a new feature in SQL Server 2019 called Certificate management in the SQL server configuration manager. Security to access SQL servers will be managed by Certificates. They authenticate secure access for SQL server instances. It eases the tasks like viewing, validating, and managing the certificates in SQL server instances.

  • Availability Groups:

It is a disaster recovery and high availability solution. The main aim of this feature is to provide enterprise-level alternatives to database mirroring. It is intended for supporting the replication environment of available databases. At the level of available replicas, the failure of available groups occurs.

  • SQL Server on Linux:

Some enhancements were made for SQL Server on Linux in 2019. Extensive support for distributed transactions and transactional replication. The support for MSDTC enables distributed transactions over SQL server Linux instances.

  • Machine Learning on Linux:

Some enhancements are made in machine learning on the Linux platform for SQL server 2019. AppContainer has changed local user accounts to SQL restricted User Group. Apart from Python and R, Java extensions are added to the SQL server. All the processes of Java, Python, and R run as Launchpad service, isolated from AppContainers. 


When we want to access an application, the data results based on our request comes from the database. It is possible with the help of SQL. SQL understands our query, navigates through the data, and retrieves the data from the database. SQL server has become most powerful with the latest features that were added to SQL server 2019. SQL Server stands in third place when compared with the most popular databases. That is the reason Professionals related to SQL have high demand.
