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

"Its robustness, scalability, availability, and performance are valuable. All these are the major attributes of a relational database for supporting a very high-volume business, and Db2 is very good in all those areas and in all those attributes."

"The solution can scale."

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

"The newly added feature of ALSM is one of the top features"

"The scalability and availability of this solution are the most valuable features."

"It's easy to search and extract data from the warehouse using queries."

"The solution is very stable, in both hardware and database."

"I can easily export that to further work on it in Snowflake."

More IBM Db2 Database pros

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

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

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

"The paramount advantage is the exceptional speed."

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

"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."

Cons

"The solution's UI hasn't been upgraded. The solution’s UI is an area to improve because the solution was developed long ago."

"The capabilities of this solution could improve."

"The technical support team is not very good when compared to the efficiency of Oracle's support."

"IBM Db2 Database is not ACID compliant, which would improve it. Db2 lacks Isolation, so when two people are trying to update the same field at the same time it can become stuck. Other newer databases do not have this issue, such as Microsoft SQL, Oracle DB, PostgreSQL, and SAP HANA."

"The solution could improve by providing more integration."

"The backup solution lacks flexibility."

"The application development requires a Java developer and not every company has these resources."

"The initial setup could be improved."

More IBM Db2 Database cons

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

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

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

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

"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."

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

Pricing and Cost Advice

"It is expensive."

"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."

"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."

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

"If I consider the price of IBM Db2 Database, I would say there are cheaper products in the market."

"Compared to other databases, Db2 is relatively cheaper."

"We did not buy it. It came with our hardware without any complimentary maintenance. If I compare Db2 Database with Oracle Database, its price is lower than Oracle Database."

"Licensing fees are on a yearly basis."

More IBM Db2 Database pricing and cost advice

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

"SingleStore is a bit expensive."

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

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

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