![]() ![]() In addition, it supports a variety of performance optimizations that are available only in commercial solutions such as Geospatial data support, concurrency without read locks, and so on (e.g. PostgreSQL is widely used in large systems where read and write speeds are crucial and data needs to validated. ![]() Performance is an area that can only be gauged by evaluating the metrics of potential scenarios, as it depends on the pure requirements of the specific user and the nature of the application. We are not afraid to add extensions to SQL or support for non-SQL features if this greatly increases the usability of MySQL Server for a large segment of our user base. One of our main goals with the product is to continue to work toward compliance with the SQL standard, but without sacrificing speed or reliability. MySQL is partially compliant on some of the versions (e.g. It might be worth noting that at the time of writing, no current version of any database management system claims full conformance to Core SQL:2011. In addition, there is a long list of supported optional features. Out of 179 mandatory features required for full Core conformance, PostgreSQL conforms to at least 160. PostgreSQL supports most of the major features of SQL:2011. The level of conformance for each feature is clearly laid out in Appendix D of the manual, and any deviations are clearly documented in the “Reference” section of the PostgreSQL manual. ![]() Having SQL compliance makes it very easy to move data from one SQL compliant database to another (e.g. This is very important when companies want to work with heterogeneous databases for an application. SQL compliance is a standard that a database must meet to implement all the structured query language guidelines and standards. It’s now owned by Oracle Corporation and offers several paid editions for proprietary use. MySQL, a relational database management system, has made its source code available under the terms of the GNU General Public License, as well as a variety of proprietary agreements. PostgreSQL is released under the PostgreSQL license, a liberal Open Source license, similar to the BSD or MIT licenses. PostgreSQL, an object-relational database system, is developed by the PostgreSQL Global Development Group, a diverse group of multiple companies and individual contributors. It’s created and supported by a worldwide community of organizations and individual developers, many of whom also live by open source values such as collaboration and volunteerism. Open source software has long-term viability and is always on the cutting-edge of technology. Open source software is freely available and may be redistributed and modified by anyone. Open source software has unique benefits-cost, flexibility, freedom, security, and accountability-that are unsurpassed by proprietary software solutions. Obviously, we’re rooting for PostgreSQL, but it is possible there are some scenarios in which MySQL best benefits the end-user. We’ve provided a summary of similarities and differences of the most commonly evaluated features and abilities between PostgreSQL and MySQL : We’ve tried to provide you with a fair and accurate comparison between the two, but in the end it is necessary to evaluate your unique scenario and determine which database is best suitable for your specific use-case. ![]() While there are many similarities and overlaps between the two databases there are also very distinct differences. An informed decision must be made after evaluating the differences and trade-offs between the two systems. There are radical differences between PostgreSQL and MySQL.
