It is important to know that the easier it is for any of the aforementioned user groups to work with the database, the lower the ongoing cost will be. This very important factor determines how efficiently your chosen DBMS can scale to meet your requirements. In other words, the capacity of the system needs to grow as your business grows and more data comes in. It is essential to estimate how easily a DBMS can manage a large scale of data, even if the database grows very quickly after the project is operational. There is a large difference between the programming languages that the PostgreSQL server supports and that of the SQL server. The programming languages supported by the PostgreSQL server are Python, Tcl, Net, C, C++, Delphi, Java, JavaScript (Node.js), and Perl.
Because of that, it has struggled to find footing among the masses, despite being heavily featured. Thus, modifications that are created for speed improvement demand more work. When it comes to performance, PostgreSQL trumps SQL Server in several ways. We touched upon partitioning, and while both PostgreSQL and SQL Server offer partitioning, PostgreSQL offers it for free, with more efficiency.

There is no cluster manager for the Read Scale Availability Group tool. Logical backup tools like pg_dump and pg_dumpall are already available within PostgreSQL. The SQL server is compatible with various hardware platforms, including trusted and untrusted operating systems, file systems, and other hardware configurations. However, the tuning process https://www.globalcloudteam.com/ of the SQL Server is normally the responsibility of a Database Administrator and, sometimes, developers. The tuning process is in place to ensure the smooth running of an application in the shortest possible period. PostgreSQL offers many features in terms of scalability and can employ several CPU cores to parallelly implement queries quickly.
Still, it’s possible to distribute data among different compartments even in SQL solutions, even if it’s slightly less efficient. MySQL supports the memory-stored table, but it can’t participate in transactions, and its security is highly vulnerable. Such tables are used only for reading purposes and can simplify exclusively primitive operations. For now, MySQL doesn’t come close to making the most out of memory-optimized tables. PostgreSQL allows scanning the entire tables of a data layer to find empty rows and delete the unnecessary elements. However, the method requires a lot of CPU and can affect the application’s performance.

MySQL supports B-tree and R-tree indexing that stores hierarchically indexed data. PostgreSQL index types include trees, expression indexes, partial indexes, and hash indexes. There are more options to fine-tune your database performance requirements as you scale. The choice between the three most popular databases ultimately boils down to the comparison of the functionality, use cases, and ecosystems. Companies that prioritize flexibility, cost-efficiency, and innovation usually choose open-source solutions.
- MS SQL Server was released under a commercial license as a part of Microsoft products.
- While PostgreSQL is free, it isn’t owned by a single organization.
- However, both SQL Server and PostgreSQL provide excellent data encryption and authentication.
- If the computed column is deterministic and an acceptable data type, it can be used as a PRIMARY KEY or index, but it cannot be used as a DEFAULT or FOREIGN KEY constraint.
- It employs several CPU cores to enforce one query quicker with the parallel feature.
- Among features SQL Server highlights for optimizing performance and speed is its In-Memory OLTP, which takes advantage of in-memory data tables that perform better than writing directly to disk.
Upgrade and migration to newer versions are at the customer’s cost. Operational costs (DBA, developer, and manager salaries) are similar to that of any other standard DBMS. In addition, if the version of the DBMS is approaching EOL, SQL Server does not provide a free upgrade to a newer version. Upgrade and migration to newer versions are at the customers’ cost.
PostgreSQL Vs SQL Server: Performance
When the application grows, a single server can no longer accommodate all the workload. Navigating single storage becomes complicated, and developers prefer to migrate to different ones or, at least, create partitions. The process of partitioning is the creation of many compartments for data in the single process.
MySQL offers ACID compliance only when you use it with InnoDB and NDB Cluster storage engines or software modules. MySQL is ranked second, leaving the leading position to Oracle, the most popular DBMS today. SQL Server follows with a slim difference, whereas Postgresql, which comes right after, is a lot less recognized.
Replication in SQL Server can be synchronous-commit or asynchronous commit. The Enterprise edition offers peer-to-peer replication, as an alternative solution to multi-master replication. The open-source PostGIS resource offers support for geographic objects. PostgreSQL was created in 1986 at the University of California, Berkeley, and first released in 1989. It has undergone several major updates since then, and the project still maintains regular releases under an open-source license. The current version of Postgres is version 13, released in October 2019, with regular minor releases since then.
Memory-optimized tables are mainly known as a SQL Server concept, but they also exist in other database management solutions. Such a table is stored in active memory and on the disk space in a simplified way. To increase the transaction speed, the application can simply access data directly on the disk, without blocking concurrent transactions. For processes that happen on a regular basis and usually require a lot of time, a memory-optimized table can be a solution to improve database performance. Postgresql also supports index-based table organization, but the early versions don’t include automated index updates (which appear only after the 11th edition release).
PostgreSQL also offers better concurrency, which is an important feature where multiple processes can access and alter shared data at the same time. The MVCC characteristic of PostgreSQL ensures a lesser chance of deadlock, only blocking if two queries try to modify the same row at the same time and serialize the updates made to that row. SQL Server has a less developed multi-version concurrency control system and depends on locking of data to avoid errors from simultaneous transactions, by default. SQL Server also offers an optimistic concurrency feature, which assumes that such issues occur rarely. So, as opposed to locking a row, it’s verified against a cached version to find if any change has taken place.
Its comprehensive graphical user interface (GUI) allows intuitive and easy work with the database while allowing you to generate statistics for your reports. SQL Server contains scalability enhancements to the on-disk storage for memory-optimized tables. The current versions offer multiple concurrent threads to persist memory-optimized tables, multithreaded recovery and merge operations, dynamic management views. The data is partitioned horizontally and maps groups of rows into individual partitions.
PostgreSQL has built-in logical backup utilities, such as pg_dump and pg_dumpall.

Operating systems, including Linux, Microsoft Server, and Microsoft Windows, are compatible with the SQL server.

If you need some information only to power the next process, it doesn’t make sense to store it in a regular table. Temporary tables improve database performance and organization by separating intermediary data from the essential information. PostgreSQL isolates processes even further than MySQL by treating them as a separate OS process. On the one hand, management and monitoring become a lot easier, but on the other, scaling multiple databases takes a lot of time and computing resources. Since the first version of MS SQL Server, it has included a very intelligent and interactive built-in database management application as well as rich GUI-based reporting tools. From installation up to any extent, the MS SQL Server database is well-equipped in terms of GUI interfaces.
As opposed to the MVCC feature, whenever a row is updated, a new version of the row is created instead of overwriting the same row and both are maintained. Gradually, the older versions move into a system database called tempdb. PostgreSQL supports index-based table organization, but the early versions didn’t use automatic index updates.
