They collect data and pass it to a central PostgreSQL installation running evaluations and analyses. Usually, one or more outward-facing MySQL instances are used in such a setup. This is particularly attractive for data warehousing solutions. Postgres forks a new process for each new client connection which allocates a non-trivial amount of memory (about 10 MB). Lastly, it should be noted that PostgreSQL and MySQL can be used in tandem. Strong performance when reading data means it’s a good option for websites and small online stores. It’s easier to find an experienced and affordable MySQL admin. The RDBMS is less demanding in terms of server resources.

This may save the use of object-relational mapping (ORM).įor small to medium web projects, MySQL is the better choice. To map complex object hierarchies or where inheritance is required as a central component of the data model, the use of the powerful ORDBMS is a good option. Furthermore, sufficient resources are available for a high-performance PostgreSQL environment.Īnother application of PostgreSQL is where a project architecture requires the management of sophisticated data models. Greater demand for stability and data consistency justifies the higher complexity of the ORDBMS. In other words, you’d use PostgreSQL to implement the website of a bank or a critical institution. Where that’s not the case, MySQL is sufficient. Use PostgreSQL if you have special database requirements. MySQL, it’s clear that they’re very different, but which of the two database management systems should you be using for your project? Fortunately, the answer is simple. MySQL also supports JSON as a data type, but it is not as powerful as PostgreSQL.īy comparing PostgreSQL vs. This allows a complex, hierarchically nested data structure to be accommodated in a single field. PostgreSQL arrays allow to store multiple values in one field. PostgreSQL, MySQL PostgreSQL tackles concurrency efficiently with its MVCC implementation, which achieves very high levels of concurrency.

However, the range of functions is smaller than with PostgreSQL. MySQL supports geodata and the associated queries since version 8. PostgreSQL has the open source PostGIS extension, which is considered one of the most mature GIS implementations. MySQL has no support for ranges on board if you need them, you have to make do with self-made alternatives. PostgreSQL provides wide support for range types, which simplifies working with ordinal values. Instead of implementing Boolean values as their own data type, Booleans are stored as TINYINT(1) type numbers.

PostgreSQL knows its own Boolean data type. When designing tables, you specify the type of data contained in individual columns. Data types are the foundation for solid database design and the productive use of a database.
