Although similar, they have some important distinctions and are suitable for separate use cases. Software developers often need to choose between these two databases. The RDBMS also has tools that promote productivity, including stored procedures, triggers, and views for reusable SQL statements. For troubleshooting any errors that occur, database administrators can use the slow query log offered by MySQL.įlexibility and productivity: The MySQL Document Store allows users to build SQL and NoSQL functionality in the same application. The RDBMS also supports advanced replication technologies for availability and disaster recovery. This data contains details about the updates on the MySQL instance. Troubleshooting and disaster recovery: For point-in-time disaster recovery, MySQL uses the data from the binary logs. Beyond these data types, software developers can implement advanced search techniques using the MySQL full-text and Unicode character set search. MySQL also supports window functions and common table expressions. For writing queries, the RDBMS also supports various data types, including: They can use the available client tools like mysqladmin and MySQL workbench. Querying and data types: MySQL is easy for software developers to set up and manage. After 2009, the InnoDB storage engine replaced MyISAM to solve performance problems. Over the years, MySQL has integrated performance improvements. MySQL is ideal for various use cases, including dynamic websites, content management systems (CMS), and embedded databases for software and hardware. It is the leading database for many popular applications, known for its reliability, stability, and security. MySQL is the most common open-source relational database. Examples include PostGIS, ZomboDB, and TimescaleDB. Beyond the query engine, PostgreSQL has an extensible architecture for easy integration of extensions. Querying also supports international character sets and full-text searching. Indexing features and pluggable architecture: The PostgreSQL query engine is sophisticated, with state-of-the-art indexing features, sharding, partitioning, and various system views and functions. PostgreSQL can authenticate with Lightweight Directory Access Protocol (LDAP) and Pluggable Authentication Modules (PAM). It uses TCP/IP sockets, firewalls, SSL certificates, roles, permissions, and row-level security (RLS). The ORDBMS also has network-level, transport-level, and database-level security features. This way, you can guarantee the durability of your write operations when a server crashes. Replication can be asynchronous, synchronous, or logical.ĭisaster recovery and security: For point-in-time disaster recovery, PostgreSQL uses write-ahead logging (WAL), a technique that logs your data in secure storage before updating your database. Multi-Version Concurrency Control (MVCC): PostgreSQL fully supports Multi-Version Concurrency Control and multi-node replication. Supported procedural languages include PL/pgSQL, Perl, and Python. Software developers can also create custom data types, functions, and procedures. PostgreSQL has some unique features, which include:ĭata types and languages: PostgreSQL is flexible and has support for multiple data types that include: It’s known for supporting advanced data types and the kinds of performance capabilities commonly found in commercial databases such as Oracle Database Service and Microsoft SQL Server. Many web, mobile, and cloud applications use PostgreSQL as a standard datastore or data warehouse. Years of development have contributed to its reliability, integrity, and accuracy. PostgreSQL is an open-source and powerful ORDBMS. The object-relational nature of PostgreSQL means it can support objects, classes, and inheritance. PostgreSQL is an innovative and enterprise-class ORDBMS that supports querying for Structured Query Language (SQL) and JavaScript Object Nation (JSON). In this article, we will learn about the main features of PostgreSQL and MySQL, compare the two database management systems, and learn when to use PostgreSQL vs MySQL. PostgreSQL is an object-relational database management system (ORDBMS), which is a relational database that uses an object-oriented database model. MySQL is a relational database management system (RDBMS). These databases are also Atomicity, Consistency, Isolation, and Durability (ACID)-compliant and enforce data integrity. Relational database schemas use primary keys, foreign keys, and transaction locks to set certain constraints in the database. A relational database is a type of database that stores data objects that have relationships with one another.
