The technical support from Teradata is quite advanced.
 

Scalability Issues

Sentiment score
7.1
IBM Db2 excels in scalability for large companies but faces challenges with horizontal scaling and increasing costs.
Sentiment score
7.4
Teradata's cloud capabilities offer flexible, efficient scalability, though some users face cost and on-premise expansion challenges.
This expansion can occur without incurring downtime or taking systems offline.
Teradata's scalability is great; it's been awesome.
Scalability is complex as you need to purchase a license and coordinate with Teradata for additional disk space and CPU.
 

Stability Issues

Sentiment score
7.7
IBM Db2 Database is highly rated for stability and reliability, though performance can dip with significant data growth.
Sentiment score
8.3
Teradata is praised for stability with high uptime, robust architecture, minimal downtime, and effective workload management despite occasional issues.
I find the stability to be almost a ten out of ten.
The workload management and software maturity provide a reliable system.
 

Room For Improvement

IBM Db2 Database needs usability, integration, and cloud improvements, plus better licensing, analytics, security, and standardization tools.
Teradata needs improvements in transactional processing, user interface, pricing, integration, analytics, scalability, AI features, and support.
It might be slightly slower than other database vendors, but it works well since banks typically do not move quickly with leading-edge technology.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
If Teradata could provide a list of certified experts, that would be fantastic.
 

Setup Cost

IBM Db2 pricing is complex and expensive, especially in Africa and the Middle East, but offers robust features.
Teradata's high pricing is justified by performance, with flexible models offering value for large projects, requiring negotiation.
Teradata is much more expensive than SQL, which is well-performed and cheaper.
Initially, it may seem expensive compared to similar cloud databases, however, it offers significant value in performance, stability, and overall output once in use.
We spent roughly $295,000 on setup costs.
 

Valuable Features

IBM Db2 Database offers SQL, Java integration, scalability, security, and seamless IBM integration for flexible, reliable enterprise applications.
Teradata offers scalable, fast processing with excellent performance, adaptability, ease of use, robust security, and advanced analytics capabilities.
IBM Db2 Database, because of enterprise performance and support, is why banks still maintain their relationship with it.
The IBM Db2 Database is trusted, and IT effort is less than any other product.
Teradata's security helps our organization meet compliance requirements such as GDPR and IFRS, and it is particularly essential for revenue contracting or revenue recognition.
The data mover is valuable over the last two years as it allows us to achieve data replication to our disaster recovery systems.

Efficient access path optimization and performance excellence with helpful support
IBM Db2 for zOS serves as the central database for all the core business applications in the two banks I work with. All applications use Db2 as a data server. We fully implement and utilize most of Db2's functionalities and capabilities for core banking business applications IBM Db2 has…
Kirk Robinson - PeerSpot reviewer
Has improved data quality, optimized reporting processes, and enabled predictive insights across business units
The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput. We have been testing that, but speed remains one of our key issues. The integration has been awesome because of the platforms and their usage, and usability is great. The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts. If Teradata could provide a list of certified experts, that would be fantastic. I rated Teradata a nine because the main area for improvement is the bandwidth of resources that could assist us in applying to our projects, specifically more certified and expert resources. The market share of Teradata professionals is limited, creating an issue for us.
