Welcome, Dev, to this journal article all about SQL Server 2016. This version of the popular database management system has brought about significant improvements and innovations, making it a game-changer for data professionals and developers alike. In this article, we will take a closer look at its features and capabilities, and how it can help you manage your data more efficiently and effectively.
Introduction to SQL Server 2016
SQL Server 2016 is the latest major release of Microsoft’s flagship database management system. It was released to the public in June 2016, and has since then received numerous updates and enhancements. With SQL Server 2016, Microsoft aims to provide a platform that can handle a wide range of workloads, from traditional transactional processing to advanced analytics and machine learning.
Why Upgrade to SQL Server 2016?
If you’re currently using an older version of SQL Server, you might be wondering what benefits you can expect from upgrading to SQL Server 2016. Here are some of the key reasons why you should consider upgrading:
Feature |
Description |
|---|---|
Increased Performance and Scalability |
SQL Server 2016 has been designed to deliver faster query processing and improved scalability, making it easier to handle large volumes of data. |
Advanced Analytics and Machine Learning |
SQL Server 2016 includes built-in support for R, a popular programming language for statistical computing and graphics. This allows you to perform advanced analytics and machine learning directly within the database. |
Enhanced Security and Compliance |
SQL Server 2016 comes with a range of security features, including improved encryption and auditing capabilities. This makes it easier to comply with industry regulations and protect your data. |
In addition to these benefits, there are many other features and improvements that make SQL Server 2016 a worthwhile upgrade for data professionals and developers.
SQL Server 2016 Features and Capabilities
Let’s now take a closer look at some of the key features and capabilities of SQL Server 2016:
In-Memory OLTP
One of the most significant improvements in SQL Server 2016 is the In-Memory OLTP feature. This allows you to store certain tables and stored procedures in memory, providing substantial performance improvements for certain workloads. In-Memory OLTP is designed to be highly scalable and can handle high volumes of data with low-latency.
How Does In-Memory OLTP Work?
In-Memory OLTP uses a new data storage format called the “memory-optimized table.” This format is designed to be highly efficient and can support highly concurrent access. When you create a memory-optimized table, the data is stored entirely in memory and is not persisted to disk by default. Instead, changes are asynchronously written to disk on a regular basis.
Along with memory-optimized tables, In-Memory OLTP also introduces another new feature called “natively compiled stored procedures.” These stored procedures are compiled to machine code instead of being interpreted at runtime, leading to significant performance improvements.
What Are the Benefits of In-Memory OLTP?
There are several benefits to using In-Memory OLTP:
- Improved performance for certain workloads, such as high-concurrency transaction processing.
- Higher scalability due to the ability to handle more concurrent users/transactions.
- Reduced storage requirements due to the ability to store data in memory instead of on disk.
Columnstore Indexes
Another feature introduced in SQL Server 2016 is Columnstore Indexes. These indexes are designed to improve query performance for large analytical workloads, such as data warehousing and business intelligence.
How Do Columnstore Indexes Work?
Columnstore indexes are different from traditional row-based indexes in that they store data by column instead of by row. This allows for more efficient compression and faster query processing. When a query is executed against a table with a Columnstore Index, the index is used to perform “batch mode” processing, which can dramatically improve query performance for large datasets.
What Are the Benefits of Columnstore Indexes?
There are several benefits to using Columnstore Indexes:
- Improved query performance for large analytical workloads.
- Reduced storage requirements due to more efficient compression.
- Improved query performance due to batch mode processing.
Built-In Support for R
SQL Server 2016 also includes built-in support for the R programming language, which is widely used in statistical computing and graphics. This allows you to perform advanced analytics and machine learning directly within the database.
How Does R Integration Work in SQL Server 2016?
R integration in SQL Server 2016 works by exposing a set of functions that allow you to run R scripts directly within the database. You can use these functions to perform data exploration, visualization, and modeling using the rich set of R libraries available.
What Are the Benefits of R Integration?
There are several benefits to using R integration in SQL Server 2016:
- Ability to perform advanced analytics and machine learning directly within the database.
- Integration with other SQL Server features, such as In-Memory OLTP and Columnstore Indexes.
- Reduced data movement and latency, as you can perform analytics directly on the data in the database.
