IBM Db2 Database vs MySQL vs Oracle Database comparison

MySQL is an open-source relational database management system (RDBMS) owned by Oracle. Before Oracle acquired the product, it was completely free for users. After the merge, the solution started offering paid services with more features, alongside a free version. MySQL can easily integrate with a wide variety of programming languages, which makes it one of the most flexible and reliable products among its competitors. This cost-effective solution helps users deliver high-performance and scalable database applications through several products. They include:

• MySQL HeatWave: This is an in-memory query accelerator for MySQL. It is a parallel, columnar, hybrid query-processing engine with algorithms for distributed query processing. This database service is used for transactions, analytics, and machine learning (ML). It offers simplified, secure real-time analytics. It can be deployed on Oracle Cloud Infrastructure (OCI), Amazon AWS, Azure, and users' data centers.
  
  
• My SQL Enterprise Edition: This edition of the solution includes the most comprehensive set of advanced features, technical support, and management tools. The combination functions achieves security, scalability, reliability, and uptime, while reducing risk, cost, and complexity, in managing MySQL applications.
  
  
• MySQL Standard Edition: This edition utilizes industrial-strength performance and reliability to help users deliver high-performance and scalable Open Transaction Processing (OLTP) applications.
  
  
• MySQL Classic Edition: This is an embedded database for independent software vendors (ISVs), original equipment manufacturers (OEMs), and value-added resellers (VARs), that are developing applications using the MyISAM storage engine.
  
  
• MySQL Community Edition: This is the free version of the product, which is supported by a large active community of open-source developers.
  
  
• MySQL Cluster CGE: This is a distributed database that combines linear scalability and high availability. It offers in-memory real-time access across partitioned and distributed databases.
  
  
• MySQL Embedded: This product offers MySQL as an embedded database and is most widely used by ISVs, OEMs, and VARs. It is utilized for making applications, hardware, and appliances more competitive by bringing them to market faster while lowering their cost of goods sold (COGs).

My SQL Features

The characteristics of each MySQL edition differ depending on what it offers and what clients it is catered towards. But the main features of the product include the following:
