Associate Director, Data Architecture at a financial services firm with 10,001+ employees

Support improves setup and maintenance while pricing influences decision

If you have a similar use case and the same deal with IBM as our company, it is definitely a good option and choice. The company I work with has more than 50,000 people and more than 500 support staff. We are not locked into one database vendor. We typically work with multiple database vendors simultaneously, selecting the top choice based on the deals we make and other considerations. We do not use IBM Db2 Database related to AI at this moment because our AI project PLC is still very small scale. We may consider it in the future if we have enough scale. Overall rating for IBM Db2 Database is 8.5 out of 10.

Solution Architect at Wipro Limited

An excellent choice for diverse data processing needs with exceptional in-memory capabilities, robust failover mechanisms, easy scalability and high performance

Scalability is its key strength. Adding servers for scalability is a straightforward process involving simply incorporating a few additional servers and recycling the cluster triggers automatic repartitioning and redistribution of data. For instance, if the initial database creation involved a hundred servers and later, four more servers are added, specific commands can be executed to increase the partitions to one hundred twenty. The data is then efficiently redistributed across the expanded partitions without the need for manual data movement, ensuring a seamless and efficient scalability process. In my current organization, approximately three projects involve the usage of SingleStore, with a team size ranging from ten to twenty individuals.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The performance of the solution is valuable."

"Reliable, robust with great features."

"The self-management and optimization features are probably the best on the market"

"The most valuable features are with the industrial side."

"We had a crash of the backup system and the IBM DB2 was always up and consistent. It's robust, and for us, it was always up and running."

"The IBM Db2 Database is trusted, and IT effort is less than any other product."

"The solution has many beneficial features, such as security, support, and stability."

"The most valuable features of this solution are security and stability."

More IBM Db2 Database pros

"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."

"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."

"The product can automatically reinstall and reconfigure in case of a shutdown."

"It's a distributed relational database, so it does not have a single server, it has multiple servers. Its architecture itself is fast because it has multiple nodes to distribute the workload and process large amounts of data."

"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."

"The paramount advantage is the exceptional speed."

Cons

"They could enhance the product's cloud integration and general-purpose database capabilities."

"GUI needs improvement."

"It might be slightly slower than other database vendors, but it works well since banks typically do not move quickly with leading-edge technology."

"Also, the website could be more intuitive. I didn't find it easy to find documentation on the website."

"IBM Db2 Database could improve the user-defined functions. There are some user-defined functions that are missing, such as the spring functions. I used to have Teradata for my projects and I was used to working in the environment. They had a good set of user-defined functions."

"It would be ideal if the solution offered backup functionality. Many similar tools already do, which means Db2 is somewhat behind the curve in terms of what a customer might expect from it."

"End-to-end encryption specifically is something the solution needs to have in the next release."

"IBM Db2 Database could improve with better security."

More IBM Db2 Database cons

"We don't get good discounts in Pakistan."

"It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks."

"For new customers, it's very tough to start. Their documentation isn't organized, and there's no online training available. SingleStore is working on it, but that's a major drawback."

"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."

"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."

"Having the ability to migrate servers using a single command would be extremely beneficial."

Pricing and Cost Advice

"Among Microsoft SQL Server, Oracle, and Db2, Microsoft SQL Server is the cheapest one, and Oracle is the most expensive one. Db2 is in the middle. As compared to SQL Server, its price could go down. It will be good for customers."

"I rate the product pricing a nine out of ten."

"We don't see what the specific price of the DB2 license is because we pay for the backup license as a package."

"It is expensive."

"It's very expensive for West African countries like ours."

"We normally handle large size businesses and as far as I am aware, the license is negotiable based on the number of users and the quantitative data."

"The solution's pricing is fine."

"The solution costs less than other products."

More IBM Db2 Database pricing and cost advice

"I would advise users to try the free 128GB version."

"They have two main options: cloud installation and bare-metal installation, each with different pricing models."

"SingleStore is a bit expensive."

"The product's licensing is not expensive. It is comparable."

"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."
