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.

Data warehousing has transformed reporting performance and now delivers near real-time insights

OpenText Analytics Database (Vertica) is a very powerful analytic database, but like any platform, there are areas where it can improve to make daily work even smoother. Better cloud-native experience is one area for improvement. OpenText Analytics Database (Vertica) was originally designed as an on-premises analytic database and later moved to cloud. Improvement opportunities include more seamless cloud-native features such as auto-scaling, serverless options, and easier cluster management. Competitors such as Snowflake and BigQuery provide more fully managed experiences. Easier UI is another area for improvement. Most administration is currently done by SQL and command line tools. An improvement opportunity would be a more modern web UI for monitoring, workload management, and troubleshooting. Faster ecosystem and community growth is needed. In short, OpenText Analytics Database (Vertica) could improve in areas such as cloud-native capability, modern UI for administration, stronger real-time streaming integration, and growing its ecosystem and community. These enhancements would make it easier to manage and adopt compared to newer cloud-first analytic platforms. From a day-to-day operational perspective, there are a few areas where OpenText Analytics Database (Vertica) could improve to make our work smoother. Smarter automatic projection management is needed with more intelligence, auto projection creation, automatic optimization, and reduced manual testing with better workload management. Right now, monitoring queries often requires system tables and manual analysis. Troubleshooting slow queries takes time. A modern real-time dashboard showing query bottlenecks and resource users would enable quick detection. The impact could be faster issue resolution and less time spent debugging performance. Storage native interaction with modern data tools is also important. In short, from a day-to-day perspective, improvements in automatic projection optimization, better workload monitoring dashboard, easier schema evolution, and stronger modern tool integration would significantly reduce manual tuning effort and improve developer productivity. While OpenText Analytics Database (Vertica) is very powerful, these enhancements would make it more efficient for the analytics team.

Quotes from Members

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

Pros

"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."

"Provides good security and reliability."

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

"Some of the best features are stored procedures, parallelism, and different indexing strategies."

"The solution is stable."

"If you have good people designing how the data is stored, it's a marvelous tool."

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

"The solution works with big data, so it's pretty scalable."

More IBM Db2 Warehouse pros

"Vertica is an excellent data warehouse platform."

"Scalability has been amazing; we have seen a lot of improvement and can describe our clusters by petabytes and scale them by the number of users, with one project having 15 to 20 consecutive users dealing with petabytes of storage."

"Vertica uses advanced Azure technologies to compress raw data using indexing, allowing a large amount of data to be stored with minimal physical space. Advanced algorithms are employed in data compression."

"Before Vertica, we used a combination of sharded RDBMSs and Hive: the typical runtime for a query was in the hours; it's now in the seconds, with way more data than then (we're talking hundreds of terabytes)."

"It maximize cloud economics for mission-critical big data analytical initiatives."

"Since moving to Vertica all the manual maintenance and speed issues of the Oracle data warehouse are left behind."

"We are able to integrate our Vertica data warehouse with Tableau to create numerous reports quickly and efficiently."

"Certain research which was unattainable beforehand, now is in reach."

Cons

"The biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."

"I previously used DataStage, which I think is better than InfoSphere Warehouse."

"Lacks sufficient documentation and particularly in Spanish."

"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."

"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."

"IBM Db2 Warehouse needs to improve its interface."

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

"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

"Vertica can improve automation and documentation. Additionally, the solution can be simplified."

"We faced some challenges when trying to use the temporary tables feature."

"Suboptimal projection design causes queries to not scale linearly."

"The explain plans are very difficult to read and understand; for one complex query the explain plan I printed out took in excess of 32 A4 pages and no visual tools were available that I could find."

"Ability to use analytic functions in where clauses, being able to use aliases in the where and order by clauses will make query writing/reading a lot easier."

"Performance of management of metadata layer (database catalog) needs improvement. We still have to have smaller customers on PostgreSQL; Vertica cannot manage thousands of schemata."

"The documentation could be improved with more examples of commands and step-by-step scenarios."

"It is usually very stable, but we occasionally see some nodes going down."

More OpenText Analytics Database (Vertica) cons

Pricing and Cost Advice

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

"It is fast to purchase through the AWS Marketplace."

"Vertica has a perpetual license, but they are currently trying to convert all those licenses to subscription-based licenses on a yearly basis."

"The price is reasonable. We use a pay per license model. Firstly, you need to buy a license. After that, you mainly pay the annual support fee of around 20% or 25%. I think their prices are quite reasonable."

"It's an expensive product"

"It's free up to three nodes and 1TB, and then get in contact with their sales guys."

"The price of Vertica is less expensive than some competitors, such as Teradata."

"The pricing could improve, it is a little expensive."

"From a cost perspective, the software is less than most of its competitors."
