We performed a comparison between IBM Db2 Database, MySQL, and Teradata based on real PeerSpot user reviews.
Find out what your peers are saying about Microsoft, Oracle, SAP and others in Relational Databases Tools."It is a scalable solution."
"The most valuable features are the simplicity of the database and the access to Db2 and Db2 information."
"The most valuable feature is PowerPC support."
"When you submit a ticket the response time is quick."
"The solution has very good data compression of up to 50%. For example, if you have 50 terabytes of data, it can be reduced to 25 terabytes."
"I have found the most valuable feature to be its availability."
"It is quite a stable solution."
"Db2 Database has given us good results since we have started to use it. We predominantly use IBM hardware, and this is one of the reasons why we started to use Db2 Database. Db2 Database has a very good HADR capability. High availability resilience is also good in this solution. It also has pureScale, which allows you to upgrade one node to get very good and high-level resilience. If you are using a database on five nodes, you can take one node down, upgrade that, and let that node up. You can then bring the second node down, upgrade that, and so on."
"I like MySQL's feature that helps to automate things."
"Compared to other databases, MySQL is cheaper and we were using the community edition which was free of cost. ML is fully integrated with the database in HeatWave. It has also many other features. MySQL is a far better solution in terms of pricing."
"While MySQL offers strong basic functionality."
"It is very easy to install and has all basic database features."
"Setup is easy. MySQL of various flavours has community editions to easily test, deploy, and run."
"The initial setup was pretty straightforward. I would have worked with our IT team in terms of the initial setup."
"For sure, the solution is very stable."
"It is free, which is probably its most valuable feature. It is a pretty full-featured relational database. It really does everything we need it to do."
"Auto-partitioning and indexing, and resource allocation on the fly are key features."
"We did performance testing. We had a set of real life MicroStrategy reports. Our conditions were: Not allowed to redesign data model, not allowed to rewrite the queries, all queries should be generated by MicroStrategy, no aggregates. Teradata appeared to be way faster than a similarly configured (in terms of hardware) Oracle server."
"Teradata can be easily used in ETL mode transformations, so there is no need for expensive and inconvenient ETL tools"
"It is a solid database a lot of different tools to move data."
"Cuts time to process huge amounts of data with efficient analytical queries."
"Teradata's pretty fast."
"Teradata solutions help organizations reduce IT, operations, and maintenance costs; enhance on-time delivery of products and services."
"It's the same as your visual database. I like the fast load feature for data, the BTQ solution is very good, and storage procedures are very fast."
"We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment."
"The queries can be difficult for beginners because there are so many. I would like to see more use cases for flow analysis that enable us to correlate the flow with events. Adding this feature in a QI format would be good for beginners."
"Microsoft SQL Server is comparatively very simple to use. I wish IBM would move towards making Db2 easy to use for both basic and advanced users. This is where I see room for advancement. Db2 is also more expensive than Microsoft SQL Server, and its price can be reduced. The replication feature needs to be there in Db2. Microsoft provides similar functionality in SQL Server. IBM also has similar functionality, but it exists in a different product. So, to have the replication ability, you have to buy a different product. It makes sense to have this functionality within Db2 instead of a different product. It will also be helpful in terms of competition. In Africa, the problem for Db2 is competition. Oracle Database and Microsoft SQL Server have been in this market for a very long time. These companies have built the ecosystem and the brand within this market for a very long time. So, they are very popular with users. Db2 or IBM came a little later in the game, and that's where the problem lies. They also don't do a lot of marketing for it, which is also a problem."
"The capabilities of this solution could improve."
"GUI needs improvement."
"The initial setup could be improved."
"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 price should be lower."
"The full-text search feature must be improved."
"The solution could improve by having better performance and security."
"While utilizing a comparable algorithm, is noted to be sensitive, especially when configuring the inner device."
"The analytics features are in need of improvement."
"We want high availability and replication features, which are currently missing in this solution. It would be great if they can provide an in-built replication feature, similar to Oracle RAC, in MySQL."
"The GUI could improve in MySQL."
"Some problems with big table operations, and a struggle to keep the servers responding in peak situations."
"They should come up with a better solution than the NDB cluster for better scaling. If they could come up with a better solution for write scaling, apart from the NDB cluster, which is supported by all open source communities, that would be great. Although the NDB cluster, I believe, is an open-source tool, it's not widely supported as a solution."
"The solution could improve by having a cloud version or a cloud component. We have to use other solutions, such as Amazon AWS, Microsoft Azure, or Snowflake for the cloud."
"Since I was working on the very basic, legacy systems, the memory thing was always a challenge. If Teradata is moving to the cloud, the space constraint or the memory issue that my company generally faces will eventually resolve, in time. What I'd like to see in the next release of Teradata is that it becomes full-fledged on the cloud, apart from better connectivity to various systems. For example, if I have to read or include a Python script, if I write some basic codes, I should be able to read even unstructured data. I know that it's not supported even in Snowflake, but at least semi-structured data support, if that can be a little more enhanced, that would be good."
"I think the UI is not there yet. It could be improved by being more user-friendly."
"Data ingestion is done via external utilities and not by the query language itself. It would be more convenient to have that functionality within its SQL dialect."
"The solution is stable. However, there are times when we are using large amounts of data and we can see some latency issues."
"GUI of administrative tools is really outdated."
"Teradata needs to pay attention to the cloud-based solution to make sure it runs smoothly."
"I'm not sure about the unstructured data management capabilities. It could be improved."
