Review summaries and opinions

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

ROI

Sentiment score
6.3
Users experience varied ROI with MySQL due to its open-source nature, cloud or local use, and operational benefits.
Sentiment score
8.1
Teradata boosts analytics speed over 100%, enhancing customer service and satisfaction, with high ROI and user approval.
 

Customer Service

Sentiment score
6.8
MySQL support is mostly community-driven and free, but Oracle's support, while effective, can be costly for smaller businesses.
Sentiment score
7.1
Teradata's customer service is praised for expertise but criticized for delays, with ratings ranging from 6 to 10 out of 10.
We have no issues and usually receive timely responses.
The technical support from Teradata is quite advanced.
Customer support is very good, rated eight out of ten under our essential agreement.
 

Scalability Issues

Sentiment score
6.7
MySQL is scalable for small to medium projects but requires enhancements and tools for effective large-scale deployment.
Sentiment score
7.4
Teradata is praised for its scalability, speed, and flexibility, despite some complexity and cost challenges in cloud environments.
Meeting scalability requirements through cloud computing is an expensive affair.
This expansion can occur without incurring downtime or taking systems offline.
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
MySQL is widely praised for reliability and performance, but occasional issues with large tables require proper maintenance and configuration.
Sentiment score
8.4
Teradata excels in stability with minimal downtime, robust architecture, 99.9% uptime, and reliable performance, despite minor large dataset issues.
We face certain integration issues, especially when we integrate the database with security solutions like IBM QRadar.
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

MySQL needs scalability improvements, better replication, enhanced security, integration, and upgraded tools, procedures, user interface, and documentation.
Teradata users seek better transaction processing, enhanced scalability, modern interface, cloud focus, advanced analytics, and improved support and documentation.
It could be more beneficial if MySQL can enhance its data masking functionality in the same way it has improved data encryption.
The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation.
Oracle could improve on scalability.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
 

Setup Cost

Enterprise buyers appreciate MySQL's flexible pricing, noting affordable options compared to Microsoft SQL Server or Oracle.
Teradata's high cost is justified by its superior performance, competitive total ownership costs, and flexible pricing models.
Oracle has different components, so if you need security, you have to procure a different license, but here everything is inbuilt and it's not costly.
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.
 

Valuable Features

MySQL is popular for being open-source, SQL-compatible, scalable, easy to manage, cross-platform, with strong integration capabilities.
Teradata offers efficient, scalable data management with fast query performance, robust security, automation, and cloud flexibility for businesses.
With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment.
My experience with MySQL is very good for organizations that consider database security and availability as priorities.
It allows programming, writing stored procedures, creating views, constraints, and triggers easily.
The data mover is valuable over the last two years as it allows us to achieve data replication to our disaster recovery systems.

Featured Reviews

Prabir Kumar Kundu - PeerSpot reviewer
Offers robust security and availability with impressive replication capabilities
Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.
