Even though firms offer comparable items, the rivalry between them is fairly typical in today’s day and age. In a competitive market, a company’s profit is shaped by delivering the finest services and goods and having the majority of clients for a certain product. Companies now have more choices than ever when it comes to databases making the market highly competitive. The choice between MySQL vs IBM DB2 in the sphere of database management is a difficult one.

MySQL is an open-source SQL Relational Database Management System that’s developed and supported by Oracle. MySQL is a popular system that can store and manage that data for you, and it’s an exceptionally popular database solution for WordPress sites. IBM DB2 is a collection of data management tools from IBM that includes database servers, augmented data explorer, and others. It’s an RDBMS that uses XML to offer object-oriented features and non-relational structures. IBM DB2 is built to effectively store, analyze, and retrieve data.

This article provides a detailed comparison of the two databases to assist businesses in deciding whether to use MySQL or IBM DB2. It includes a quick overview of both MySQL and IBM DB2 as well as the elements that influence the MySQL vs IBM DB2 choice.

What is MySQL?

MySQL was developed by MySQL AB (now Oracle Corporation) of Sweden. MySQL is an Open-source Relational Database Management System (RDBMS) that was first released in 1995 and is used to store, retrieve, update, and administer databases. There are several MySQL variations in the market today, and most of them have identical functionality and syntax. Linux, Mac OS, Windows, Free BSD, Solaris, and more systems are all supported. MySQL is exclusively available in English and was written mostly in C and C++.

MySQL allows many users to access databases and run queries using the SQL language. MySQL RDBMS is frequently used in Linux distributions in conjunction with Apache and PHP Web Server.

What is IBM DB2?

DB2 was originally built by IBM for their own platform. Since 1990, the company has been working on a Universal Database (UDB) DB2 Server that can run on any authoritative operating system, including Linux, UNIX, and Windows. DB2 is a relational database for transactional workloads that provides comprehensive Data Management and Analytics features. This operational database is compatible with Linux, Unix, and Windows operating systems and is designed to give high performance, actionable insights, data availability, and dependability.

In-memory technology (IBM BLU Acceleration), powerful administration and development tools, storage optimization, workload management, actionable compression, and continuous data availability are all included in the IBM DB2 database software (IBM pureScale).

MySQL vs IBM DB2: What are the Differences?

Here are the factors that you may consider while comparing MySQL & IBM DB2 Databases:

MySQL vs IBM DB2: Platform Support

MySQL runs on Microsoft Windows, Linux, Mac OS, OpenBSD, HP-UX, AIX, IBM I, OpenSolaris, Symbian, Oracle Solaris, FreeBSD, ArcaOS, and IRIX, among other platforms. It is compatible with practically all common operating systems.

IBM DB2 database application development is also possible on a variety of operating systems and architectures.

The following operating systems are supported by DB2 database applications:

  • AIX®
  • Linux®
  • Windows
  • Mac OS X 
  • HP UX

MySQL vs IBM DB2: Programming Language Support

MySQL is compatible with a variety of programming languages like PHP, C, C++, Java, and so on. It was built using a multi-layered server design to enable multithreaded kernels and multiple CPUs. TCL, Perl Scheme, and Haskel are among the additional languages supported. This characteristic is what makes it so popular among programmers.

IBM DB2 database applications may also be written in several languages: C++, C#, VB.NET, and many more.

MySQL vs IBM DB2: Features

First and foremost, MySQL is an Oracle-backed open-source and publicly accessible database system. It is simple to use and provides the user with both a GUI (MySQL Workbench) and a command-line interface (mysqladmin). MySQL may be spread via the Internet, allowing users to view and modify data from any location at any time. MySQL secures its connections with encryption technologies.

MySQL is quicker, more reliable, and less expensive simply due to its efficient architecture. Its server provides faster results than other databases without sacrificing the software’s core capabilities.

MySQL effectively saves data in the database, ensuring that it does not include duplicate information. MySQL is based on an engine that is well-suited to OLTP and excels at optimizing the number of transactions per second in your database.

The IBM DB2 Database on IBM Cloud Pak® for Data combines a tried-and-tested, AI-infused, enterprise-ready Data Management System with an integrated data and AI platform built on the secure, scalable Red Hat® OpenShift® foundation. Machine Learning incorporated into query processing can be used to get insights, and reduce expenses by eliminating the requirement for Data Duplication and Migration with multimodal capabilities. Further, by using DB2 on any Cloud vendor, you may increase agility.

MySQL vs IBM DB2: Scalability 

MySQL Enterprise Edition includes the MySQL Thread Pool to provide consistent performance and scalability as a user, query, and data loads grow. The Thread Pool is a highly scalable thread-handling model that helps you manage client connections and statement execution threads more efficiently.

While threading improves scalability, MySQL still lacks genuine scaling, particularly when working with Big Data.

Vertical Scalability is a strength of IBM DB2, which is also a weakness of open-source RDBMS like MySQL. Even commercial databases like IBM DB2, on the other hand, struggle a little with Horizontal Scalability. Scalability is achievable, however, intricate setups including masters, slaves, replication, failover servers, and other factors necessitate a significant amount of effort.

IBM has just released pureScale, a new solution for DB2 that accomplishes three impressive feats:

  • Horizontal Scalability: Add extra nodes to the cluster to virtually increase capacity.
  • Application Transparency: No modifications to the code are required.
  • Constant Data Availability: Regardless of whichever server breaks, the system will continue to function, although at a lower throughput.

MySQL vs IBM DB2: Security Features 

While important corporate capabilities, such as Transparent Column or Table Encryption, are lacking from MySQL, it still has a robust set of security protections that should be suitable in virtually all cases. For anybody with more stringent security requirements, the ability to design and deploy bespoke authentication and audit plug-ins may be a valuable advantage.

IBM DB2’s security is defined by a security plan, executed via privilege and authority management, and fortified by auditing protected data access. A security strategy identifies your organization’s security goals and the policies and practices that will be used to achieve them. Security auditing allows you to evaluate and assess the sufficiency and efficacy of the policies and processes you’ve implemented to protect your data.

IBM DB2 uses authorization identifiers (IDs) and roles, as well as the rights that are allocated to them, to manage access to its objects and data. You may perform specified actions on an item using each privilege and its associated authority.

To secure your sensitive data, you can utilize the DB2 Secure Socket Layer (SSL) support or built-in Data Encryption mechanisms. You may also safeguard your datasets with RACF® or a comparable system.

MySQL vs IBM DB2: Pricing

MySQL is available in a variety of commercial versions to satisfy your technical and business requirements, as shown below:

  • Cluster Carrier Grade Edition costs $10,000 to $30,000 (1-4 socket server)
  • Cluster Carrier Grade Edition costs $20,000 to $60,000 (5+ socket server)

Key Challenges of Working with MySQL

When compared to commercial databases, MySQL’s development and debugging tools are lacking. COMMIT, stored procedures, and ROLE are not supported in MySQL versions below 5.0. MySQL is prone to data corruption due to its poor transaction management. SQL check restrictions are also not supported by MySQL.

Key Challenges of Working with IBM DB2

The usage of DB2 causes the product’s GUI to slow down over time. Performance time for the Big Board report, topology report, View Component Events window, and other aspects of the GUI may decline as data is added to the database. Stale index statistics, which can arise when a high volume of data is added to tables, create these performance issues.
