Advanced features enhance business intelligence, but complex management calls for improved user guidance

While my experience with IBM Db2 Warehouse is somewhat limited, when compared to other databases such as Oracle, there are areas for improvement. They need to enhance the database to make it more user-friendly and easier to master. They should implement a more comprehensive graphical user interface with additional features. For instance, when users encounter problems, the system should provide better guidelines and troubleshooting directions, except for hardware-related issues. They need to implement tools that would help users perform basic troubleshooting rather than solely relying on support. Other databases have features where users can investigate specific issues using error codes. From my experience, many minor issues could be resolved before escalating to support.

Quotes from Members

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

Pros

"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."

"Provides good security and reliability."

"The solution is stable."

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"The most valuable features of IBM Db2 Warehouse include its availability, easy integration, ability to deal with a large size of data, excellent performance with no delays, powerful security mechanisms, and effective support."

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."

"It can be mounted on the cloud, which is a huge plus. If the client, for example, starts small with on-premise deployment and then it rapidly needs to grow, we can transfer this to the cloud easily."

More IBM Db2 Warehouse pros

"BTEQ is the best feature of Teradata, as it allows me to execute multiple queries such as select, insert, update, and delete in a single script, handle errors, automate running multiple SQL statements, and schedule ETL jobs, making it lightweight and scriptable, unlike SQL Assistant."

"I found all parts --loading, transformation, processing & querying work in parallel, and end-to-end-- to be valuable."

"It has given our business the ability to gain insights into the data and create data labs for analysis and PoCs."

"Auto-partitioning and indexing, and resource allocation on the fly are key features."

"It is a stable program."

"It's very, very fast"

"Their extensive experience in data warehousing, the platform's performance, and their strong reputation in the market are the most valuable."

"The cloud is ten times better than physical hardware; it is more cost-effective and the upgrade process is ten times easier."

More Teradata pros

Cons

"Lacks sufficient documentation and particularly in Spanish."

"It takes a long time to have a new version or release, similar to Oracle."

"In terms of improvement, IBM Db2 Warehouse should be more scalable."

"There should be more material available for training and training should be free."

"The primary challenges customers face with IBM Db2 Warehouse are related to its complexity in usage. It requires highly skilled professionals who understand Db2, and both training and support are challenging to obtain."

"There were some initial challenges with IBM Db2 Warehouse about eight months ago when I worked in this environment. When I coordinated with IBM support, they mentioned that the memory was insufficient for our needs. Our business environment required significantly more memory than the previous cluster could provide. Consequently, we have worked closely with on-site IBM technical personnel to address this issue."

"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."

"The biggest challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."

More IBM Db2 Warehouse cons

"There is some improvement required on OLTP level and some analytical function is missing."

"I would like to see more integration with many different types of data."

"Teradata is a bit late for the cloud."

"I would not say it was very performance efficient, but it was definitely good."

"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."

"If I want to implement an upgrade, I'd like to see how it will be different. Ideally, Data Lab should help me test production items and also do future things. Future releases should be downloadable and testable in Data Lab."

"The solution is stable. However, there are times when we are using large amounts of data and we can see some latency issues."

"The capability to implement it with comparable performance across various private cloud environments, ensuring adaptability to different infrastructure setups would be beneficial."

More Teradata cons

Pricing and Cost Advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."

"It's a very expensive product."

"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."

"Teradata is not cheap, but you get what you pay for."

"Users have to pay a yearly licensing fee for Teradata IntelliFlex, which is very expensive."

"Price is quite high, so if it is really possible to use other solutions (e.g. you do not have strict requirements for performance and huge data volumes), it might be better to look at alternatives from the RDBMS world."

"Teradata is currently making improvements in this area."

"The cost of running Teradata is quite high, but you get a good return on investment."

"The price of Teradata is on the higher side, and I think that it where they lose out on some of their business."
