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
7.3
SQL Server offers high ROI through cost-effectiveness, automation, and ease of deployment, with returns often within a year.
Sentiment score
8.1
Teradata boosts analytics speed over 100%, enhancing customer service and satisfaction, with high ROI and user approval.
All applications need our repository to provide services for our online business or our customers, so the return is good.
 

Customer Service

Sentiment score
6.5
Microsoft support offers valuable online resources, but experiences vary with concerns about wait times and language issues.
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.
When we created support tickets, the experience was very positive.
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
7.0
SQL Server is generally scalable and effective, but large datasets and costs pose challenges requiring maintenance and infrastructure adjustments.
Sentiment score
7.4
Teradata is praised for its scalability, speed, and flexibility, despite some complexity and cost challenges in cloud environments.
The server where we installed it has grown from 64 gigabytes in RAM to 256 gigabytes, demonstrating significant scalability capabilities.
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
7.6
SQL Server is highly stable and reliable, with most issues resolved by updates, receiving high satisfaction ratings.
Sentiment score
8.4
Teradata excels in stability with minimal downtime, robust architecture, 99.9% uptime, and reliable performance, despite minor large dataset 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

SQL Server needs better pricing, integration, security, performance, and support, with improvements in Management Studio, encryption, and cloud services.
Teradata users seek better transaction processing, enhanced scalability, modern interface, cloud focus, advanced analytics, and improved support and documentation.
I would appreciate using Microsoft Pro as it can integrate with Excel or, with a simple query, consume information from the database using Microsoft Excel.
When we consider the price for replication in another site, the pricing becomes prohibitive.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
 

Setup Cost

SQL Server pricing is costly but cheaper than Oracle, with various licensing options and a free Developer Edition available.
Teradata's high cost is justified by its superior performance, competitive total ownership costs, and flexible pricing models.
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

SQL Server offers dynamic resource allocation, high availability, performance, security, integration, ease of use, scalability, and extensive support.
Teradata offers efficient, scalable data management with fast query performance, robust security, automation, and cloud flexibility for businesses.
I have been working with SQL Server for a long time, and it works well for me as I am using it in different applications, such as web applications, Windows applications, or the data warehouse reporting.
The always-on feature provides high availability in SQL Server.
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

Gus Mtz - PeerSpot reviewer
Availability and financial reporting thrive with robust integration tools
The best features of SQL Server are availability and stability. We never have concerns about the database. The ability of SQL Server to integrate with other Microsoft services, such as Azure for supporting business intelligence or data analytics, is primarily through Power BI for analytics tools. We use Power BI, but not in the cloud. We have interfaces with other databases. We extensively use the ETL tools of SQL Server for integrating with other databases or text files. The ETL tools are excellent for making jobs that run daily or hourly. For disaster recovery features supporting mission-critical applications in our organization, we have implemented the high availability feature of SQL Server. The always-on feature provides high availability in SQL Server. We use this tool daily for our risk management application.
