PostgreSQL vs MySQL: What You Need to Know

The debate between PostgreSQL vs MySQL has served food for thought and fueled an age-old debate for DevOps users. Building scalable, stable, and customizable databases requires foresight and knowledge of the two most successful and widely adopted SQL options ever. 

Both these SQL languages have their respective pros and cons as highly versatile, open-source database servers. However, to opt for the right SQL option, it’s essential to pit PostgreSQL vs MySQL and decide on the clear winner.

A comparative study of the two systems allows us to pontificate on their applications in modern SDLCs.

Understanding PostgreSQL

Learning and practicing PostgreSQL is synonymous with Structured Query Language (SQL). The ORDBMS language was launched 30 years ago for commercial and in-house enterprise software development.  

Ever since the system has been a pall-bearer for SQL-compliant database technology. On the other end, PostgreSQL is highly extensible and compliant with Object-RDBMS concepts such as table linking and synchronous-asynchronous delivery.

SQL handles various data types, irrespective of their structure; which ranges from:

·       Structured

·       Semi-structured, and

·       Unstructured

PostgreSQL brings some proprietary RDBMS solutions and features that augment its performance and versatility. PostgreSQL is mature enough to handle large, complex queries and is easy to customize as per your immediate needs.

Its client-server database model is exceptionally resilient and easy to commandeer with a CLI. Postgres’s versatility has got it adopted in FinTech, analytics, and of course, standard, dynamic web portal, and application development.

The further addition of a SQL Interpreter as a language in the 90s helped expand its functionalities. Postgres’ long-winded existence has espoused a sea of documentation and support material to help you take your SQL learning forward. There are several Postgres extensions available for real-time incorporation into backend codebases.

Pros of PostgreSQL

1.               It is highly capable of multitasking

2.               Used extensively by eminent corps such as Yahoo, Facebook, and Apple for their DBMS requirements

3.               Extensive library support for DBMS operations

4.               Offers analytical functions

5.               Highly programmable and provides supports for third-party tooling

6.               Built-in JSON support is performant

Cons of PostgreSQL

1.               Interoperability issues, especially if you run the same codebase with different versions of PostgreSQL, on different machines

2.               Horizontal scalability is difficult with PostgreSQL

3.               Workability is impeded when operating on modern file systems, e.g., raw audio/video.

4.               Difficult to operate locally

5.               JSON data types require expert query handling capabilities

Understanding MySQL

postgresql vs mysql

MySQL has been the preferred SQL alternative for developers and businesses that require relational DBMSs. MySQL was built to ensure query language programming remains fast, customizable, and developer-friendly. 

The database language has steadily competed with PostgreSQL since the former’s inception. MySQL is compatible with the LAMP stack suite of applications.

MySQL has evolved over the past 26 years of its existence. Over the years, it’s supported Machine Language based automation, which simplifies database operations.

As a general-purpose RDBMS, MySQL can be scaled up to support various types of web services and applications. This has allowed modern businesses to adopt MySQL for API–driven web software, real-time applications, etc.

MySQL caters to services that render real-time analytics for multi-client systems. MySQL’s performance further outshines projects with Online Analytical Processing or OLA and Online Transaction processing, i.e., OLTP.

Oracle, the MySQL source code owner, has launched MySQL compatible data integrator, middleware, data recovery, and security solutions.

This language is better at handling structured types of data. MySQL also offers premium-grade database security. Hence, you will find it running under the hood of some of your favorite services and brands, such as Twitter, GitHub, Google, Flickr, WeChat, Youtube, etc.  

Pros of MySQL

1.               A high-speed transactional processing system

2.               High-grade security and stability that guarantees high uptime for digital products

3.               Immensely easy to learn (extensive documentation, guidance, support)

4.               Supports Common Table Expressions just like PostgreSQL

5.               Adaptable for both small-scale and large-scale enterprise and commercial applications while maintaining compatibility with a broad array of programming languages

6.               Highly customizable so that it works with a diverse spectrum of infrastructure configurations

7.               In-built geospatial data types and functional support for geographic data mapping

Cons of MySQL

1.     Still lacks documentation for some essential utilities, such as data replication operations

2.     Manual migrations are safer than automated migrations

3.     The non-relational DBMS module scope, a legacy feature addition to RDBMSs these days, is not on par with the RDBMS capabilities

4.     Poor performance scalability and high processor requirements

5.     Joining capabilities demand further fine-tuning

6.     Has no analytical functions

PostgreSQL vs MySQL: Comparison and Contrast of Attributes

GOVERNANCE MODELOpen-source license; source code is held by the PostgreSQL Development GroupGNU license facilitates open-source code. It is currently owned by Oracle Corp, with premium versions boasting extended features
