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.

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

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.

Quotes from Members

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

Pros

"It has a good, stable performance."

"Db2 database scalability and performance capabilities match our database needs. It covers pretty much everything a database administrator or engineer might need."

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

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

"The solution's security is very tough and impenetrable."

"The solution can scale."

"The IBM Db2 multi-workload helps me manage diverse business applications with easy management."

"The most valuable features of this solution are security and stability."

More IBM Db2 Database pros

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

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

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

"The paramount advantage is the exceptional speed."

"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'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."

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

Cons

"Its process of building up queries could be more accessible."

"I would like to see some artificial intelligence brought into the solution."

"The ease of use, or ease of management, could be improved."

"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 initial set up was complex."

"The backup solution lacks flexibility."

"The product’s user interface is not easy to use."

"We need some time to improve the performance. We have to perform a weekly REORG, or else RUNSTATS for the databases."

More IBM Db2 Database cons

"SingleStore can be improved in the aspect that the Azure pipelines do not have many parameterization features compared to others, for example, AWS."

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

"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."

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

"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."

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

Pricing and Cost Advice

"I would rate the pricing a five out of ten. It's not super expensive, but also not cheap."

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

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

"Db2 is less expensive than Oracle."

"The solution's hardware and subscription model for support are very expensive."

"It is expensive when compared to other products."

"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."

"It's very expensive for West African countries like ours."

More IBM Db2 Database pricing and cost advice

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

"SingleStore is a bit expensive."

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

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

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