Valuable Features

IBM Db2 Database excels in powerful SQL dialect, multi-platform support, self-tuning memory management, Java integration, reduced administration costs, security, reliability, and seamless IBM product integration. Its scalability, high availability, automatic storage management, programming capabilities, and ease of use are highly valued. The database provides robust data analytics, high performance, and effective data replication with minimal downtime, while maintaining strong security features and compatibility with diverse business applications.
  • "Db2's best features are that it's self-maintaining and self-monitoring, which means I have to view and monitor the database far less often."
  • "It's the best solution in terms of security, performance, and availability because the system is available 24/7."
  • "I'm using this solution for a financial network; I make and prepare the databases for analysis."

Room for Improvement

IBM Db2 Database faces challenges in user interface enhancement and support for easier application development. Licensing is complex and costly, with high maintenance charges. The tool's integration capabilities and its compatibility with other platforms can be improved, including improved cloud readiness. Simplified management, improved scalability and performance, and better monitoring tools are desired. Its data retrieval speed should be enhanced, and automatic upgrade processes need reliability improvements. Security and advanced feature support also need addressing.
  • "There are some issues with Db2's database file system not being readable. The storage could also be increased, and the monitoring could be improved."
  • "The problem with this environment is that any software that you install is very costly because there are no free tools for this environment."
  • "Technical support isn't very helpful when I've had problems."

ROI

Organizations reported a substantial ROI from IBM Db2 Database. They implemented various business projects seamlessly and noted a significant financial gain of approximately 100 billion in their currency. Users praised IBM Db2 Database for its strong performance and positive impact on organizational efficiency. Although specifics were not always available, the financial benefits were acknowledged, especially in long-term usage despite initial expenses. Many users found the return on investment exceptionally positive.

Pricing

IBM Db2 Database is often perceived as expensive, particularly when compared to other solutions like Microsoft SQL Server. Licensing fees are typically annual and can vary depending on use and features. While Db2 tends to be less costly than Oracle, its pricing lacks transparency and can be complex—especially for cloud environments. Negotiations can lead to more favorable rates, especially when bundled with IBM Power Systems. Many users appreciate its comprehensive feature set despite the higher costs.
  • "I rate the product pricing a nine out of ten."
  • "The total cost of the solution depends upon the PVU licensing"
  • "We purchase the product's yearly license."

Popular Use Cases

Organizations primarily use IBM Db2 Database for various banking systems, including core banking, online transactions, financial software, and ERP systems. It supports data lake deployment, serves as a primary data warehouse, handles large transaction volumes, and is used for OLAP and data analysis. Financial and retail sectors often utilize it for transaction management and asset management. Some use it as a relational database management system on mainframes, integrating legacy systems with modern environments.

Service and Support

Customer service and support of IBM Db2 Database receive positive feedback, with users praising its reliability, knowledgeable staff, and quick response in critical situations. However, some note long response times and varying efficiency among support team members. Support ratings range from good to excellent, with suggestions for improved documentation and faster communication. North American users report better experiences than international ones due to local representation issues. Frequent users find IBM Db2 support satisfactory and effective.

Deployment

Many users found IBM Db2 Database's initial setup straightforward, especially those with experience. Some stated it ran smoothly on various operating systems, though Linux required added libraries. Experienced teams handled setups efficiently, while others considered it complex, particularly when switching from Oracle. Documentation and forums were helpful for guidance. Skilled personnel could complete setup quickly, but in intricate environments, expert assistance was necessary. Complexity arose with large-scale deployments and specialized configurations.

Scalability

IBM Db2 Database is generally praised for its scalability, capable of handling large user counts and transactions. It depends on the investment and specific infrastructure used, such as cloud setups, which facilitate scalability without significant challenges. Some reviewers indicate that scaling horizontally can be challenging and comes with higher costs. IBM Db2, comparable to other databases like Oracle, offers robust scalability, particularly in environments utilizing IBM hardware or cloud services.

Stability

IBM Db2 Database is described as highly stable by many users, with instances running smoothly for multiple years. It remains reliable without crashes or glitches, even under high data load. However, some reported performance issues with growing data or multiple queries. Organizations rate its stability between eight and ten out of ten. Its longevity and feature set are noted, being regarded as ahead of its time in offering advanced database capabilities.

IBM Db2 Database Reviews Summary
Author infoRatingReview Summary
Associate Director, Data Architecture at a financial services firm with 10,001+ employees4.0We use IBM Db2 Database for financial services due to its enterprise performance and support. While Oracle may have superior technology, IBM's pricing is favorable. Although slightly slower, IBM Db2 meets our needs, especially given Oracle's rising costs.
Network Administrator at GAEB4.5I’ve used IBM Db2 for 20 years to support various business applications. It’s secure, easy to manage, and reliable, though expensive to upgrade and difficult to use across sites. Support and cloud migration need improvement.
Database Admin Senior Consultant at a consultancy with 10,001+ employees4.0In our organization, IBM Db2 Database is used for banking and entertainment sectors, supporting OLTP and warehousing. Its optimizer plan is valuable, though stability and lack of a free version limit its appeal compared to open-source options like Postgres.
Consultant at Discount Bank4.5IBM Db2 for zOS is central to banking applications, valued for its performance and features like access path optimization and effective buffering. While complex, it offers long-term financial benefits over other vendors like Oracle and Microsoft.
Mainframe Technical Manager/Service Integration Lead at Saudi Business Machines4.5We continue using IBM Db2 for its high availability and active-active configurations. However, IBM's support has weakened, requiring thorough testing due to defect-related outages. Despite this, Db2 remains more reliable than Oracle RAC or Microsoft SQL for critical 24/7 operations.
Data Engineer at a tech services company with 501-1,000 employees3.0I use Db2 to pull data for Snowflake reporting. It's easy for SQL and exporting, but the UI is old and scalability is poor for an on-premises solution. Stability is 7/10. I rate it 6/10; it's good for those adopting the IBM stack.
Senior project manager (APAC region) at FreeBalance4.5In our project, we use IBM Db2 to convert data from a mainframe to our GRP solution, enhancing its scalability and reliability. Although the interface needs improvement compared to Oracle, both databases have unique strengths suited to different needs.
Product Owner at ABN AMRO Bank N.V.3.5We use IBM Db2 for managing large data volumes in mainframe environments due to its interoperability with IBM systems. However, it lacks cloud integration and database capabilities compared to Oracle and Microsoft SQL Server, prompting our switch to Oracle for better cloud compatibility.
