However, if you require frequent data reads, MySQL is preferred. If your application requires frequent data updates, PostgreSQL is a better choice. Read about LAMP stacks » Performance requirements It typically requires complex infrastructure setup and troubleshooting experience. PostgreSQL, on the other hand, can be much more challenging for newcomers. It’s simple to set up MySQL as a standalone product or bundle it with other web development technologies like the LAMP stack. It takes less time to build a new database project from scratch.

MySQL is more suitable for beginners and has a shorter learning curve. However, you can start a MySQL project if you want to prototype, create internal applications with fewer users, or create an information storage engine with more reads and infrequent data updates. PostgreSQL is better suited for enterprise-level applications with frequent write operations and complex queries. However, you may consider the following factors before making a final decision. In contrast, PostgreSQL supports the INSTEAD OF trigger, so you can run complex SQL statements using functions.īoth relational databases are suitable for most use cases. That means the procedure will run automatically before or after the user modifies the data. In a MySQL database, you can only use AFTER and BEFORE triggers for SQL INSERT, UPDATE, and DELETE statements. TriggersĪ trigger is a stored procedure that runs automatically when a related event occurs in the database management system. While both MySQL and PostgreSQL support stored procedures, PostgreSQL allows you to call stored procedures written in languages other than SQL.

You can reuse the same code repeatedly, which makes database management tasks more efficient. Stored procedures are structured query language (SQL) queries or code statements you can write and save in advance. Materialized views improve database performance for complicated queries. For example, you can precompute some values in advance (like the total value of all orders over a given period) to create materialized views. While MySQL supports views, PostgreSQL offers advanced view options. ViewsĪ view is a data subset that the database system creates by pulling relevant data from multiple tables. PostgreSQL also supports other additional data types like arrays and XML.

Working with PostgreSQL is more intuitive for database developers. Objects support paradigms like parent-child relationships and inheritance. Objects are a common data type in many programming languages like Java and. This means that in PostgreSQL, you can store data as objects with properties. PostgreSQL, on the other hand, is an object-relational database. There are more options to fine-tune your database performance requirements as you scale. PostgreSQL index types include trees, expression indexes, partial indexes, and hash indexes. MySQL supports B-tree and R-tree indexing that stores hierarchically indexed data. You can index frequently accessed data by configuring the database management system to sort and store it differently from the other data. Indexesĭatabases use indexes to retrieve data faster. MySQL databases do not offer MVCC, but PostgreSQL supports this feature. When you use MVCC, multiple users can read and modify the same data simultaneously without compromising data integrity.

Multiversion concurrency control (MVCC) is an advanced database feature that creates duplicate copies of records to safely read and update the same data in parallel. PostgreSQL is fully ACID compliant in all configurations.

MySQL offers ACID compliance only when you use it with InnoDB and NDB Cluster storage engines or software modules. For example, if you update a large number of rows but the system fails midway, no row should be modified. ACID complianceĪtomicity, consistency, isolation, and durability (ACID) are database properties that ensure a database remains in a valid state even after unexpected errors. While PostgreSQL and MySQL are conceptually similar, there are many differences to consider before implementing them.
