Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"MariaDB is stable and the initial setup is straightforward.""The solution runs very quickly. It's not slow at all.""The most valuable feature is that it uses multiple cores, which is better than some of the other databases.""What I like best about MariaDB is that it is open-source and reliable.""MariaDB is easy to install and is stable and scalable.""The stability of MariaDB is good, it has high availability.""The most valuable feature of MariaDB is that it is open-source and we can easily migrate from other databases, such as Oracle to MariaDB.""It's easy to set up."

"It has completely met our needs. It works, and it is robust. We haven't had any problems with what PostgreSQL does for us and the way it does it. That's why we've been using it for so long. We understand it, and it does the job.""The community support and the open-source community for it are good.""The solution is quite stable.""We managed to reduce the storage space needed to 10% of the original size, without affecting data integrity, and we significantly improved the performance.""The database has excellent performance.""It is easy to use.""It is very simple to manage.""It's a standard reliable database management system."

More PostgreSQL Pros →

"The performance could be a bit better.""MariaDB can improve by adding more features. There are a lot of features, which are available in Oracle, and which are not available in MariaDB. We hope they will introduce the features soon.""The maintenance and performance could be a bit better.""Replication could be better, and it's not so simple. It would be better if they had a replication server. It would make things a lot easier. You need to have that replication server, but not in the same server farm. Then there will be a bit of latency between both because you should have one in one city and another one in a different city. That kind of solution should be more baked into every single database today. Mirroring the database in a live environment where any record written on the production server replicates instantly across the fiber on the other server wasn't easy. Many people don't even bother with that, and they just run one server.""The price could be less expensive.""The solution should do some fine-tuning on maybe the transaction per second so that users can get more than they can on the Microsoft SQL Server.""It does not have tools for debugging procedures and functions.""The license should be cheaper and closer to that offered by MySQL, Oracle and other products."

More MariaDB Cons →

"It could be improved by using parallelization. You want basically, distributed computing.""There are some products out there that have a slightly different method of implementation for the SQL language. Some of those are slightly better in some areas, and PostgreSQL is slightly better in some areas. I would probably like to match all of those products together. It is just down to the functionality. For example, Oracle has a number of options within SQL that are outside of what you would class as the SQL standard. PostgreSQL misses some of those, but PostgreSQL does other things that are better than what Oracle does. I would like to merge those two products so that there is a certain amount of functionality in a single product.""When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties.""The user interface could be a bit better.""They need to have a better graphical interface. There is a tool called pgAdmin 4 that they use, which is free. It is written in Java, and it is slow. They need to have a better product that is similar to Toad for Oracle, but, of course, it is hard to get something that's really great and free. Other than that, it is great.""If it was free to use, it would be the perfect solution.""As PostgreSQL is an open-source product, you do have to do a bit more configuration and management yourself.""The solution needs to improve the query, documentation, and JSON data functionality."

    MariaDB is an open source relational database created by the original founders of MySQL. It is considered one of the most popular and trusted database servers throughout the world. MariaDB is a valued component found in most cloud offerings and is the default in many Linux tools. It is also widely used by Wikipedia, WordPress, and Google, among other well-known sites. Maria DB easily melds data into concise information from a vast array of applications, such as banking, online shopping, websites, and more.

    MariaDB was originally created to improve MySQL performance. It is the most widely chosen database server due to the solution being super fast, robust, user-friendly, and easily scalable. MariaDB also offers a substantial ecosystem of plugins, storage engines, and numerous other valuable tools that make it very attractive for a significant offering of use cases.

    The solution’s newest functionalities include compatibility with Oracle Database and Temporal Data Tables, and advanced clustering with Galera Cluster 4, which make it easier for users to research data history from any point in the past. Additionally, the most recent versions include JSON and GIS features. MariaDB is committed to staying an open source solution.

    MariaDB Features

    • More storage: MariaDB works with more storage engines than MySQL and most other database servers available. Some storage options include, but are not limited to ARCHIVE, MERGE, CSV, MEMORY, BLACKHOLE, MyISAM, ColumnStore, MyRocks, and Cassandra.

    • Super fast: MariaDB offers faster authentication checks. The FlushSSL permits SSL certificates to be reloaded without a server restart, resulting in huge time savings.

    • Improved testing: MariaDB offers an extending testing suite that runs faster and can test more than ever before. Bugs can be easily fixed and invalid tests removed.

    • Genuinely open source: Every code in MariaDB is GPL, LGPL, or BSD. Client libraries [for Windows (ODBC), Java (JDBC), or C] allow linking to closed source software. All fixed bug cases and development plans are completely public. MariaDB is a community-developed solution representing the true spirit of open source products.

    Reviews from Real Users

    Faustine C., Engineering Supervisor- Corporate Data Solutions and Services at TZ Telecoms Corporation, shares, “The software provides a lot of information on what is happening inside the database. For most performance parameters it is easy to know if something is not right in the configuration or optimization which helps engineers take remedial fine-tuning measures. For example, if the database is underperforming it is easy to know which performance parameter can be adjusted to handle the workload. It is difficult to troubleshoot database issues if many performance parameters can not be monitored or debugged which is the case with some database management systems. It provides great monitoring of data storage, processing, and performance stability which is really important for real-time data storage and processing. It's a user-friendly product.”

    A PeerSpot user who is a Senior Engineer at a tech services company relates, “ The solution's high availability is its most valuable aspect. We have found the product to be stable and the initial setup is pretty simple. I'd rate the solution at a ten out of ten. I'm very happy with it overall. I would recommend the solution to others. It's easy to find details about the product online and to learn about it.”

    PostgreSQL is a powerful and fully-featured database management system with which business owners can create object relational tables. It is an open source project that can be acquired for free and heavily focuses on elements such as extensibility and strict standard compliance. PostgreSQL is a flexible server system that can manage large workloads that are being contributed and accessed from a wide range of locations such as in a network, as well as small-scale projects like a single machine or user.

    Some technical details of interest about PostgreSQL include:

    • Its MVCC (Multi-inversion concurrency control) allows fluid changes to be made to the system without cumbersome roadblocks, while maintaining the optimal level of ACID.
    • Replication, built-in binary replication is available from the 9.0 version and later.
    • It offers a wide range of indexing capabilities, including B-tree and hash indexes, as well as GIN and GiST (generalized inverted indexes and generalized search trees).
    • It uses procedural languages that make it easier for developers to expand the database.
