High-speed data processing, seamless scalability, and excellent high availability making it an optimal choice for those prioritizing performance and efficiency in a database solution

There's a noteworthy consideration when it comes to collecting massive amounts of data. It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks. Attempting to use it for direct extraction, for instance, might lead to memory-related challenges. While MySQL version five might lack extensive SQL capabilities, SingleStore also has its constraints, requiring simpler SQL writing. This becomes evident when seeking advanced functionalities like window functions or JSON functions, where SingleStore doesn't offer an extensive toolkit, necessitating a more straightforward approach to SQL.

Quotes from Members

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

Pros

"When you submit a ticket the response time is quick."

"It is a scalable solution."

"It's a very mature product."

"We had a crash of the backup system and the IBM DB2 was always up and consistent. It's robust, and for us, it was always up and running."

"The most valuable features are the simplicity of the database and the access to Db2 and Db2 information."

"The valuable features include access path optimization, excellent performance, a robust locking mechanism, parallelism, and effective buffering in memory."

"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."

"The solution helps secure the database."

More IBM Db2 Database pros

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

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

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

"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 paramount advantage is the exceptional speed."

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

Cons

"IBM Db2 Database could improve in the steps it takes for upgrades. It is not an easy process. The process of upgrading the version is lengthy and requires a lot of time. To make it more efficient, I suggest implementing some automation on the solution side. This will greatly reduce the time required for the upgrade."

"The licensing fees can be reduced."

"I would say that the tool has to be made more cloud-friendly and should have agreements with AWS, Microsoft, or Google to run things on hyperscalers."

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

"IBM Db2 Database is not ACID compliant, which would improve it. Db2 lacks Isolation, so when two people are trying to update the same field at the same time it can become stuck. Other newer databases do not have this issue, such as Microsoft SQL, Oracle DB, PostgreSQL, and SAP HANA."

"In terms of improvements, IBM Db2 can improve its interface and its functionality. Also, the embedded functions should be much richer than the current ones - the functions which are embedded in the engine itself."

"The user interface is old and needs to be improved."

"It would be ideal if the solution offered backup functionality. Many similar tools already do, which means Db2 is somewhat behind the curve in terms of what a customer might expect from it."

More IBM Db2 Database cons

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

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

"Having the ability to migrate servers using a single command would be extremely beneficial."

"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."

"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."

Pricing and Cost Advice

"It is expensive."

"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."

"Clients are required to purchase a license."

"Compared to Oracle, it is so much cheaper."

"We don't see what the specific price of the DB2 license is because we pay for the backup license as a package."

"Db2 is less expensive than Oracle."

"The solution costs less than other products."

"I rate the product pricing a nine out of ten."

More IBM Db2 Database pricing and cost advice

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

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

"SingleStore is a bit expensive."

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

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