IBM DB2 vs Microsoft SQL Server vs MySQL: What are the differences?

Key Differences between IBM DB2, Microsoft SQL Server, and MySQL

1. Data Types and Features: IBM DB2 offers a wide range of complex data types and advanced features which are more extensive compared to Microsoft SQL Server and MySQL, making it suitable for enterprise-level applications requiring intricate data handling.

2. Licensing Cost and Support: Microsoft SQL Server is known for its licensing cost, which could be higher compared to MySQL, which is open-source, and IBM DB2 which offers a range of editions with varying costs. Additionally, Microsoft SQL Server provides robust support services while MySQL relies heavily on community support.

3. Scalability and Performance: IBM DB2 boasts superior scalability and performance optimization, making it a preferred choice for large-scale applications handling massive datasets. Microsoft SQL Server and MySQL are also scalable but may require additional configuration for high-performance requirements.

4. Platform Support: Microsoft SQL Server primarily runs on Windows-based systems, while MySQL and IBM DB2 offer cross-platform support, including Linux and UNIX, providing flexibility in deployment environments.

5. Integration and Ecosystem: Microsoft SQL Server seamlessly integrates with other Microsoft products like Azure, providing a comprehensive ecosystem for development and deployment. MySQL, being open-source, has a wide range of third-party tools and community support, while IBM DB2 offers integration with IBM's larger suite of enterprise solutions.

6. Security and Compliance Features: IBM DB2 is known for its robust security features and compliance standards, making it a top choice for industries with stringent data regulations. Microsoft SQL Server and MySQL also offer security features but may require additional configurations for enterprise-level compliance requirements.

In Summary, the key differences between IBM DB2, Microsoft SQL Server, and MySQL lie in the data types and features offered, licensing cost and support, scalability and performance, platform support, integration and ecosystem, and security and compliance features.

While there's been some very clever techniques that has allowed non-natively supported geo querying to be performed, it is incredibly slow in the long game and error prone at best.

MySQL finally introduced it's own GEO functions and special indexing operations for GIS type data. I prototyped with this, as MySQL is the most familiar database to me. But no matter what I did with it, how much tuning i'd give it, how much I played with it, the results would come back inconsistent.

It was very disappointing.

I figured, at this point, that SQL Server, being an enterprise solution authored by one of the biggest worldwide software developers in the world, Microsoft, might contain some decent GIS in it.

I was very disappointed.

Postgres is a Database solution i'm still getting familiar with, but I noticed it had no built in support for GIS. So I hilariously didn't pay it too much attention. That was until I stumbled upon PostGIS and my world changed forever.

MySQL	Microsoft SQL Server	IBM DB2
The MySQL software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.	Microsoft® SQL Server is a database management and analysis system for e-commerce, line-of-business, and data warehousing solutions.	DB2 for Linux, UNIX, and Windows is optimized to deliver industry-leading performance across multiple workloads, while lowering administration, storage, development, and server costs.
