One downside is that during restoration, if there is a technical glitch, the process enters a rollback phase, which takes a considerable amount of time to bring the database back up. Review collected by and hosted on G2.com.

It was easy to use and integrate to our system. My Finance team uses this extensively and are really happy with the many features it provides. The way daily transactions are handled is amazing and the support for AI tools is an added advantage. It was really easy to implement to their work flow and they use it daily. Customer support is also really nice. Review collected by and hosted on G2.com.

There not a single thing I dislike about Db2. Review collected by and hosted on G2.com.

I have used IBM DB2 for around 5 years for one of my legacy projects I was working on. Even though we have millions of records terabytes of data. The database was performing well. There is provision of vacuum for faster query performance and reindexing of whole database would also increase performance. There were no chances of it went down due to technical error. It provides a Linux interface allow technical people like me to use it Easly. I would definitely recommend it to others. Review collected by and hosted on G2.com.
