Microsoft SQL server is a relational database management system (RDBMS) developed and marketed by Microsoft. It runs on a variety of operating systems including Windows and Linux. It is used in a wide range of applications, from data processing and analytics to business intelligence. It also includes tools for development and deploying databases.
It is built on the Structured Query Language, or SQL. There are several versions of SQL server, each improved upon its predecessor. The first version, SQL server 1.0, was a 16-bit server for OS/2 that started to become available in 1989, and it continued to evolve. You can click here for more info about the best MS SQL Server.
MS SQL Server is a powerful relational database management system, and it is widely used by businesses. It allows the user to create and edit tables, store information in them, and retrieve it as needed. It also has a lot of features that make it easy to use, which makes it popular among developers.
There are many different editions of SQL server, aimed at different audiences and workloads. Some of these editions are free, while others cost money. For example, the company sells an Express version that is aimed at smaller databases.
This edition is free for testing purposes and can support up to 10 GB of storage space. For large applications, Microsoft sells an Enterprise edition.
It was formerly only available on the Windows platform, but in 2016 the company made it available on Linux. This move bolstered Microsoft's position in the enterprise market and opened up new opportunities for it to attract customers who don't run Windows or have mixed-server environments.
Currently, there are four primary editions of SQL server: Developer, Express, Standard, and Enterprise. All of them include the same bundled services, but each one offers different features and limits on the number of processor cores and memory that can be configured in a database server.
The primary editions offer a range of features for database administration and data warehousing. These include support for in-memory OLTP, polybases, columnstore indexes, and partitioning. In addition, there are a number of security and performance features.
Another feature of the DBMS is a locking mechanism that monitors all threads that acquire locks on objects in the database to prevent deadlocks. When one of the threads reaches a deadlock, SQL server automatically takes remedial action to resolve it. You can find more details on this site about the MS SQL Server.
This includes killing the deadlocking thread or rolling back a transaction that caused the lock. This can help improve performance and scalability for complex database operations, as it ensures that the same transaction does not occur repeatedly.
It also has a command line interface that allows you to write SQL queries and execute them. You can also use the SSMS tool to manage your database, as it exposes most of the SQL Server management features.
In-memory OLTP is one of the key features added to SQL Server 2014. This feature stores data in a memory-optimized table instead of traditional disk-based ones to improve performance for online transaction processing applications. The technology also integrates a buffer pool to boost I/O throughput. Check out this related post that will enlighten you more on the topic: https://en.wikipedia.org/wiki/Microsoft_SQL_Server.
