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.

An easy-to-deploy solution that can be used for data ingestion and usage
I work for a fintech company where we create several strategies generally built on finance data, which are like one-time series data. We deal with huge bulk data on a daily basis, and we use kdb+ for data ingestion and usage The most valuable feature of kdb+ is the speed at which it returns the…

Quotes from Members

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

Pros

"The most valuable features are the simplicity of the database and the access to Db2 and Db2 information."
"IBM DB2 pureScale Feature is valuable."
"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 easy to search and extract data from the warehouse using queries."
"The self-management and optimization features are probably the best on the market"
"Your iOS, your throughputs, your performance cycles, you cannot touch it with Microsoft or with Oracle scalability-wise. That is far and away the most scalable systems and the highest performing systems of the set of them."
"It is a scalable solution."
"It is quite a stable solution."
"The solution returns data quickly, and data retrieval is fast in kdb+."
 

Cons

"We need some time to improve the performance. We have to perform a weekly REORG, or else RUNSTATS for the databases."
"IBM Db2 Database could improve with better security."
"The problem with this environment is that any software that you install is very costly because there are no free tools for this environment."
"The solution could improve by providing more integration."
"The product needs to improve its configuration and storage."
"It would be helpful to have more querying tools and more development tools for us to work easily with Microsoft."
"I would like to see some artificial intelligence brought into the solution."
"The management of Db2 should be simplified because there are not too many specialists in this area, and the learning curve of Db2 specialists is very long. After the courses, probably it takes one and a half or two years to get to the point when you are using the product properly in the production systems. So, the complexity is very high, and the most important thing is to simplify the management of the product, including self-maintenance. They should simplify the installation, management, and monitoring to simplify the product. It takes too long for a person to be a specialist in this product."
"The solution should have a more user-friendly user interface."
 

Pricing and Cost Advice

"They are competitive and honest (compared to how peer firms approach licensing conversations). ​"
"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."
"It is expensive. The price depends on the size of the machine on which you are installing the Db2 and the features you are using. It also depends on the country. IBM has different policies and different options for payment for this product."
"Db2 is less expensive than Oracle."
"The solution costs less than other products."
"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."
"We don't see what the specific price of the DB2 license is because we pay for the backup license as a package."
"I would rate the pricing a five out of ten. It's not super expensive, but also not cheap."
