Windows SQL Server
Unbind your productivity with Windows SQL Server
Microsoft will never stop supplying professionals with the resources they need from simple and efficient software to complicated OSes and apps such as Windows SQL Server.The SQL Server is a Microsoft relational database management system designed and developed to organize and analyze data with a framework that supports various business intelligence, analytics and transaction processing operations. The information stored on the server is held in the relationship database. However, since the system is something more than a database, it also requires a management system. SQL stands for Structured Query Language, a programming language that controls and manages the server, and there are several iterations of the SQL server, with each subsequent version being an enhanced variant of its predecessor. Microsoft SQL Server has a wide range of business programs available. The first and most obvious is that the database is used to store and manage information. Moreover, businesses that maintain confidential consumer information such as personal data, credit card information and other protected data will benefit from increased security. The system also allows the sharing of data files between computers on the same network, a factor that improves reliability. The SQL server is also used to increase the speed at which the data is processed, making it easier to run large operations. With information saved in the archive, organizations can have a secure backup method.
Top features of Windows SQL Server
Intelligent Query Processing enhancements
This is a series of improvements that affect the behavior of the Database Optimizer, a component within the SQL Server that generates query execution plans. This includes dynamic memory grants for rowstore tables, table variable deferred compilation, batch mode for rowstore, and more. These are all behind-the-scenes enhancements to the Query Optimizer that will boost the consistency of the plans for all relevant queries. This indicates improved overall results after the update. Test your problem queries on a development instance to search for progress. It's one of those great improvements that doesn't need any significant changes from the useer.
Accelerated Database Recovery (ADR)
This is really a new way for SQL Server to conduct a database recovery in the event of a transaction being rolled back, an instance restart or an Availability Group failure. Rather than the often volatile time spent waiting for the database recovery to run, the SQL team has re-developed how recovery operates and drastically shortened how long this process takes. Anyone who has had to wait for an instance of SQL Server output to roll back a long transaction, or who has had an unfortunate crash during a large data project, knows how difficult it is to only wait for the recovery to be completed so that you can get back to work. ADR will offer benefits to SLA and RTO all around.
Encrypted with Secure Enclaves
It's the next edition of AlwaysEncrypted, the encryption innovation introduced in SQL Server 2016 that enables transparent column encryption without allowing administrators to access decryption keys. Using the new Secure Enclaves technology, SQL Server can now securely encrypt a part of memory for computing these encrypted columns without any unencrypted values being exposed to the rest of the processes. Security issues and technical problems, too. Database servers are best equipped to process large amounts of data so that they are always encrypted and complex manipulations are the best of both worlds. When you're already using AlwaysEncrypted, no major changes are needed other than reconfiguring and re-encrypting the columns of interest. If you're not using AlwaysEncrypted, it's a good time to investigate, test this function, and see if it fits your security standards.
Query Store Custom Capture Policies
Query Store is a powerful tuning and trending tool for storing, calculating, and repairing plan regressions within the SQL Server database. One downside to using it, however, is that often too much information may be processed, even for queries that the DBA might not be interested in or for queries that were part of a system utility or a monitoring tool. This new functionality of custom policies ensures that you can fine-tune precisely which queries should be monitored based on their execution statistics, such as how long they run, the CPU they use, and more. The Query Store is a great function, but it's not as useful if it consumes a lot of resources and is too bloated to be successful for the DBA. This function would allow fine tuning in such a way that it is still powerful and lean and simple to use for fixing plan issues. You'll need to sit down to see what kind of execution conditions you want to use as a filter for your query shop. Implementing this is only a matter of using a new syntax after that.
Memory-optimized Tempdb Metadata
The SQL team has improved the tempdb code so that some of the metadata that can be a bottleneck to tempdb heavy systems can depend entirely on memory and be optimized for RAM access. Why this matter: high volume, large-scale environments that use a lot of tempdb run into this kind of bottleneck. Typically this involves some kind of refactoring to minimize the use of tempdb. With this feature in place, it is possible to allow the metadata to be stored in memory and accessed optimally. This way is going to get rid of these problems.
Internal Performance Improvements
There are several internal performance improvements made by the SQL team for each and every new version that is released. There is a new index optimization for indexes with sequential key, improved temp table recompilation, improved indirect checkpoint scalability, and more. These are all performance enhancements that come "out-of-the-box", optimize standard SQL Server processes and require no effort on the part of the client to benefit from them. This is due to the care and passion put into all of Microsoft’s products.
Last Actual Execution Plan DMF
This is a new approach management function called sys.dm exec query plan stats that will monitor the last ACTUAL execution plan for a query if you allow a lightweight query profiling feature (which you should most likely do). Previously, taking an actual query plan involved either a Profiler Trace, an XEvents Trace, or an ephemeral DMF call that would lose its contents when the query was executed. Not the simplest or most convenient methods to do what is a crucial phase in any kind of production efficiency scenario.
Verbose Truncation Warnings
Every single T-SQL developer understands the pain and grind of a truncation mistake. Some value doesn't fit under a new data type, but you don't get any details at all. Then it's a lot harder than it sounds until you eventually sort out the value of the offending person. Not the best experience for what should be an easy matter to solve! This makes a difference, because mental health matters. These new messages will give you all the details of the data truncation problem so that you can just solve it and get on with your day.
Another main feature of SQL Server is compatibility for the Python programming language, an open-source language that is widely used in analytical applications. In addition, SQL Server R Services has been named Machine Learning Services and expanded to run both R and Python applications. Originally, the machine learning tool set and a wide range of other features are only available in the Windows version of the database software, with a more restricted set of features supported by Linux.
Resumable Index Build
SQL Server now has the power to prevent an index from restoring, to catch pace with the work that has been completed so far and to restart at some other point in time. some people still need index reconstructions and use so many resources that they still have to deal with the reality of maintenance windows, even with the ONLINE alternative. The problem, however, is what happens if you run out of time during the maintenance window? Initially, you'd have to cancel your reconstruction, wait for a possibly long recovery, and then start again from scratch. This new feature is going to get rid of these problems.
Make use of great hardware
Even if you've published optimal queries and dealt with all other possible concerns that could hold back SQL server efficiency, but if you have enough CPU overhead to handle processes that are central to the proper functioning of the database. Fortunately, CPU upgrades are becoming a more economical way, and chips with a lot of physical cores and more logical threads can have less cash than you could expect. Briefly, a combination of hardware and software tweaks will give you a boost in the performance of your SQL server, which will give you the potential to unlock your productivity to the fullest.
What are Windows SQL Server editions?
Windows SQL Server 2019
SQL Server 2019 incorporates new features and adjustments that focus on performance, security, and increased work volume data. SQL Server 2019 enables users to join SQL Server, HDFS, and Spark containers together with a new Big Data Cluster feature. SQL Server 2019 is much better that it ever was before. It also includes column store index builds, rebuilds, and static data masking. Enhanced Data Recovery is also new, which also performs and undoes the redo phase of the oldest page log sequence number. As an example, this is done in the event that the user closes an application that has been running for an extended period so that the user does not have to wait too long for the application to close. If you want to opt for the newest and best version available in the market, than Windows SQL 2019 is the most compatible with your needs.
Windows SQL Server 2017
Microsoft SQL Server has been operating on Windows for more than 20 years. But in 2017, made DBMS available on Linux, especially when it was initially released as a community technology preview and initially dubbed SQL Server Next. SQL Server 2017also expanded Docker support for Windows systems to include Linux-based containers in the previous version. It is still a proper choice for everyone to consider, because it is still relevant and ready to take on any challenge you throw it its way .Windows SQL Server 2017 can get the job done without asking for a lot of hardware requirements, making it a good fit for those who have been running business for a while.
Windows SQL Server 2016
In comparison to previous versions. SQL Server 2016 introduced new features for performance tuning, real-time operating analytics, and data visualization and reporting on mobile devices, plus hybrid cloud support that enables DBAs to work databases on a combination of on-site systems and public cloud resources to minimize the costs. SQL Server Stretch Database technology, for example, has rarely accessed data from on-site storage devices to the Microsoft Azure... cloud, even though it is extremely important to keep data accessible for querying. SQL Server 2016 also expanded support for broad data analytics and other top notch analytics applications through SQL Server R Services, which also allows DBMS to run analytics applications written in the open source R programming language, and PolyBase, a technology that allows SQL Server users to access data. Windows SQL Server 2016 was a great jump towards the future, and it still holds up for future use.Read more
Windows SQL Server 2014
SQL Server 2014 introduced In-Memory OLTP, that also enables users to run online payment processing (OLTP) applications to data stored in memory-enhanced tables instead of standard disk-based ones. Another new update of SQL Server 2014 was the barrier pool extension, which also incorporates the SQL Server buffer pool memory cache with a solid state drive with another feature intended to strengthen throughput by unloading data from standard hard disks.
Windows SQL Server 2012
Earlier iterations included SQL Server 2005, SQL Server 2008, and SQL Server 2008 R2, which was considered the largest release. Next up are SQL Server 2012 and SQL Server 2014. SQL Server 2012 has provided unique features, such as column store indexes, which can be used to store information in a column-based format for data storage and analytics, and AlwaysOn Availability Groups, high availability, and disaster recovery technology. If you want an effective server with great features, and compatible with almost every available hardware in the market than Windows SQL Server 2012 is more enough to deliver you the best experience.
Windows SQL Server 2008
SQL Server 2008 R2 allows users to tap into the powerful business intelligence features of SQL Server by deep integration with popular Microsoft applications such as Excel. Compared to its predecessor, SQL Server 2008, is more efficient, with support for up to 256 logical CPUs. Moreover, a new Unicode compression scheme, USC-2, can save up to 50% of Unicode data storage specifications. PowerPivot enables all kinds of users to import, evaluate and export data as well as to create reports using the popular Excel interface and language. Master Data Services is a one of a kind and improved feature designed specifically to help an organization build a data structure and hierarchy so that data collected and used across multiple departments, databases are standardized and classed. This ensures that the different databases are interoperable. Windows SQL Server 2008 will always be iconic and effective even if it misses some of the new features in the latest version.
