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.
