Customer support is very good, rated eight out of ten under our essential agreement.
The technical support from Teradata is quite advanced.
 

Scalability Issues

Sentiment score
7.7
Oracle Database In-Memory scales efficiently for thousands of users, supporting large setups with minimal performance impact and high satisfaction.
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
7.5
Oracle Database In-Memory is highly rated for stability, reliability, and support, suitable for high-transaction systems with resource needs.
Sentiment score
8.3
Teradata is praised for stability with high uptime, robust architecture, minimal downtime, and effective workload management despite occasional issues.
It was very difficult to move data from on-site to cloud in one attempt at the start, because we didn't have sufficient bandwidth to copy the data files to the cloud.
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

Oracle Database In-Memory needs enhancements in analytics, scalability, security, cost efficiency, interface, and AI integration for optimal use.
Teradata needs improvements in transactional processing, user interface, pricing, integration, analytics, scalability, AI features, and support.
Enhancing features like CAG augmentation and cache augmentation could significantly optimize performance for large language models.
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

Oracle Database In-Memory is costly, justified by performance, but may deter smaller companies despite recent cloud cost reductions.
Teradata's high pricing is justified by performance, with flexible models offering value for large projects, requiring negotiation.
Recent reductions in cloud costs and learning opportunities, such as free portals for students, make the pricing reasonable without hindering access to powerful features and performance.
The pricing for Oracle Database In-Memory is more affordable.
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

Oracle Database In-Memory enhances performance, real-time analytics, security, flexibility, and transaction efficiency for large data volumes and data warehouses.
Teradata offers scalable, fast processing with excellent performance, adaptability, ease of use, robust security, and advanced analytics capabilities.
The valuable features of Oracle Database In-Memory include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics.
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.

Laksiri Bala - PeerSpot reviewer
Faster processing and improved memory operations have enhanced transaction and analytics efficiency
The valuable features of Oracle Database In-Memory include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics. It also offers specific memory areas, like in-memory cache, that act as intermediaries between disk and buffer cache. This feature helps organizations handle real-time memory requirements effectively.
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.
