Room For Improvement

IBM Db2 Database needs usability, integration, and cloud improvements, plus better licensing, analytics, security, and standardization tools.

SingleStore users need improved Azure integration, better documentation, advanced SQL features, and optimized data handling and server tools.

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

Error handling needs attention. When it fails due to memory, it only indicates that but not exactly in which process it failed.

Support improves setup and maintenance while pricing influences decision

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

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.

Real-time analytics has transformed daily decisions and delivers fast dashboards from streaming data

Senior Software Engineer at Honeywell

The best features SingleStore offers include fast data recovery and data compression by 80 percent. Having the information in sheets helps me to process the information quickly. Simplicity in T-SQL is another aspect I appreciate. Data recovery and sheet-based processing help my team on a day-to-day basis by enabling us to handle information efficiently. I would like to add that the data compression by 80 percent helps us in an excellent way since we are very fast in obtaining the data for our dashboards and the compression of the information is great. SingleStore has impacted my organization positively by enabling us to run low-latency analytics and model-driven use cases at scale, which is quite difficult for OLAP and OLTP databases alone. It has been very helpful because our internal clients are happy to have the data and make data-driven decisions easily. Making decisions based on data within a two-hour delay to the transactional database is excellent since we went from twenty-four hours to two hours. I think the best contribution is decision-making with data that is close to reality. Reducing that delay from twenty-four hours to two hours has significantly affected my team and business outcomes by increasing productivity. We have been able to serve all our customers, and they are very happy. We can deliver to them on time.
