What is the Difference Between MySQL and PostgreSQL?

🆚 Go to Comparative Table 🆚

MySQL and PostgreSQL are both popular relational database management systems, but they have some key differences:

  1. Database Technology: MySQL is a purely relational database, while PostgreSQL is an object-relational database. This means that PostgreSQL offers more complex and sophisticated data types, allowing objects to inherit properties.
  2. Data Type Support: PostgreSQL has a more extensive set of built-in data types, including support for arrays, hstore, JSON, and geometric types. MySQL has a more limited set of data types, but it offers spatial extensions for geographic information system (GIS) data.
  3. SQL Compliance: PostgreSQL is known for its high level of SQL standards compliance, while MySQL has limited support for certain database features like views, triggers, and procedures.
  4. Case Sensitivity: MySQL is not case-sensitive, while PostgreSQL is case-sensitive. When writing queries, you don't need to capitalize strings as they appear in the database for MySQL, but you do for PostgreSQL.
  5. Performance: MySQL has a reputation for being fast at reading data, especially when using the MyISAM engine. However, when using the InnoDB engine (which allows transactions, key constraints, and other important features), performance differences between MySQL and PostgreSQL are negligible.
  6. Compatibility: MySQL is highly compatible with many different types of data storage engines, while PostgreSQL is highly compatible with many different NoSQL databases.
  7. Support and Community: Both MySQL and PostgreSQL have large and helpful community support. Professional support packages are available from private service providers if higher levels of support are required.

In summary, if your application requires complex data types or needs to adhere to SQL standards, PostgreSQL might be a better choice. On the other hand, if you need a database with a strong focus on performance and compatibility, MySQL could be more suitable.

    • Comparative Table: MySQL vs PostgreSQL

    Here is a table comparing the differences between MySQL and PostgreSQL:

    Feature MySQL PostgreSQL
    Data Type Support Limited set of data types, with spatial extensions for GIS data More extensive set of built-in data types, including arrays, hstore, JSON, and geometric types
    SQL Compliance Less strict adherence to SQL standards High level of SQL standards compliance
    Application Scope Better suited for prototyping, internal applications with fewer users, and data storage with more reads and infrequent data updates Better suited for enterprise-level applications with frequent write operations and complex queries
    Case Sensitivity Not case-sensitive, no need to capitalize strings in queries Case-sensitive, need to capitalize strings exactly as they appear in the database
    Storage Size Stores data within the index, making them larger Doesn't store data within the index, potentially smaller storage size
    Compression Offers compression through plugins Offers data compression

    Both MySQL and PostgreSQL are relational database management systems that store data in interrelated tables. MySQL is more popular and powers many web applications, while PostgreSQL offers more features, flexibility, and data types, making it more suitable for enterprise-level applications.
