SQL Server 2022 and its previous versions

SQL Server 2022 is one of the leading software products in the field of data management and is widely used in businesses. In this article, we aim to provide a concise overview of the program’s benefits and its development.

What is SQL Server?

SQL Server is a relational database management system (RDBMS) developed by Microsoft. Companies of all sizes use it to store, manage, and retrieve data. A wide range of features makes SQL Server a data management tool that stands out for its powerful performance and flexibility.

What does SQL stand for?

SQL stands for Structured Query Language, a standardized programming language used to manage data in relational databases. SQL was defined as a standard by the International Organization for Standardization (ISO).

What is a relational database management system?

A relational database management system enables the storage and management of data in a structured manner. The data is organized into tables that can be linked to one another via keys. The tables consist of rows and columns. Each row represents a single object—in a business context, for example, a customer or an item. Each column represents an attribute of the object, such as the name or the price.

The data is therefore not only stored and retrieved, but also linked together through relationships—this type of organization enables efficient queries and, furthermore, analyses.

Features and Functions of Microsoft SQL Server

So what are the features of Microsoft SQL Server that make it a flexible and efficient data management tool? Among its most important features are:

• Performance: SQL Server offers extremely powerful data management capabilities that can process large volumes of data quickly and efficiently.
• Flexibility: The specific features of SQL Server make it possible to tailor data management to the specific needs of businesses.
• Security: A range of security features ensures that data can be effectively protected against unauthorized access.

SQL Server supports T-SQL (Transact-SQL), a Microsoft extension of SQL, and offers various services for analysis, reporting, and integration. In addition, there are tools such as SQL Server Management Studio for access and development.

The History of SQL Server

The long history of SQL Server dates back to 1989. That year, the first version was released, which was available for MS-DOS and OS/2. Over time, the server program has undergone continuous development—and starting with SQL Server 2017, it was extended to run on Linux systems. Today, SQL Server is one of the most popular database management systems on the market.

What versions of SQL Server are available?

The current version is SQL Server 2022, which builds on all the versions previously released by Microsoft. Each version has introduced new features and improvements.

Between 1995 and 2016, Microsoft released ten major versions of SQL Server. These range from simple departmental applications to enterprise solutions that compete with other major database systems. Over time, features for the web, the cloud, and mobile devices have been integrated.

Microsoft introduced columnstore indexes and AlwaysOn Availability Groups in SQL Server 2012 to improve data warehousing and disaster recovery. SQL Server 2014 added In-Memory OLTP and buffer pool expansion to boost performance.

SQL Server 2016 —developed under a “Mobile First, Cloud First” strategy—introduced performance optimizations, real-time analytics, data visualization for mobile devices, and hybrid cloud support. It enhanced big data analytics with SQL Server R Services and introduced PolyBase to access Hadoop and Azure data. This version ran only on 64-bit servers and supported Docker containers.

SQL Server 2017, available for Linux for the first time, expanded Docker support and introduced Python support. Machine Learning Services support both R and Python.

SQL Server 2019 introduced Big Data Clusters, improved Columnstore indexes, and accelerated data recovery. Always On Availability Groups were simplified, and new Polybase connectors and query processing improvements were introduced.

To reduce costs, pre-owned software solutions are a smart option. Benefit from savings of up to 75% — with full functionality and uncompromised quality.

What should you keep in mind when migrating to SQL Server?

To ensure that the task is carried out in an organized, thorough, and successful manner, the following points should be kept in mind:

• Planning: Before migrating the data management system, it is important to determine the objectives, the scope, and the resources required for the migration—and, of course, the timeframe within which it should take place.
• Testing: It is essential to test the migration before the rollout to identify and resolve potential issues early on.
• Training: Having staff who are adequately trained for the task is also an important prerequisite for a successful SQL migration.
