Delivers consistent performance and enables advanced analytics across complex data environments
Teradata stands out as a solid platform for managing and analyzing large volumes of data. Its architecture allows information to be processed efficiently while maintaining stable performance, even in highly demanding environments. One of its most notable strengths is the ability to run complex queries at high speed, which is essential for organizations that require timely and reliable analytics. Teradata offers a well-integrated ecosystem that supports working with different types of data and enables scalability as organizational needs grow. Its focus on advanced analytics, integration with modern business intelligence tools, and the ability to operate both on-premise and in the cloud make it a versatile solution for data warehousing and large-scale processing. Teradata's stability, technological maturity, and the availability of strong documentation and best practices are noteworthy. I consider Teradata to be a tool with great potential for any organization looking to enhance its analytical capabilities, optimize data processing, and move toward more data-driven decision-making. Teradata stands out as a solid platform for managing a large volume of data in different projects. Its architecture allows information to be processed efficiently while maintaining stable performance, even in high-demanding environments. A well-integrated AI ecosystem that supports working with different types of data and enables scalability as organizational needs grow across different kinds of enterprises or organizations. The focus on advanced analytics integration with modern business intelligence tools is particularly valuable. Teradata combines a powerful parallel process and optimizing SQL engine with a highly scalable architecture allowing businesses to execute complex queries and analytics in real-time. It supports multi-cloud, hybrid, and on-premise environments, giving organizations flexibility to choose the setup that best aligns with their strategy. One of the biggest strengths is the ability to unify disparate data sources and support high concurrency, enabling different teams, such as analytics, operations, BI, and data science, to access consistent, trusted data across the enterprise.

Quotes from Members

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

Pros

"The performance is okay as long as the volume of queries is not too high."
"It is stable when there is support from IBM."
"The performance is okay as long as the volume of queries is not too high."
"The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
"It will be MPP, so performance should improve."
"One of the most amazing features of dashDB is how it uses compression to get results in lighting speed."
"DashDB is a good product to work with and the extra cost you spend on performance, technical support and tools to work with is worth it."
"I like that the dashDB solution is built on DB2 technology, which means that you can use all the features of a DB2 database while outsourcing all the hardware and software maintenance."
"In Data Lab, you can schedule any testing you want to do in production. You can take a small subset of data from production, copy it there, and run all your tests. It reduces your testing costs because it's all in the lab."
"Auto-partitioning and indexing, and resource allocation on the fly are key features."
"It handles large amounts of information with a linear performance increase, in relation to a HW investment."
"The most valuable features of Teradata are that it is a massively parallel platform and I can receive a lot of data and get the queries out correctly, especially if it's been appropriately designed."
"Technically, it has made data processing much faster than other SMP databases."
"The flexibility in design is very good."
"The solution scales well on the cloud."
"Things have started moving faster in my company, such as data retrieval happens more quickly."
 

Cons

"Right now, we are implementing on ESX VMware 6.0. Support for this platform is poor. Also, one of the backup/recovery options is broken and IBM is not addressing the issue."
"The support channels need to improve."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
"I would like to see improvements in backup and authentication. It needs the ability to increase the number of retained backups to more than 2 days."
"I would rate the level of dashDB support 3.5/5. While they are very knowledgeable in many areas, you can still struggle to get the correct resolution."
"Db2 is not a solution that I recommend. We have a lot of experience and we are not satisfied with the product or the support that we received."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"Needs compatibility with more Big Data platforms."
"I'm not sure about the unstructured data management capabilities. It could be improved."
"Data synchronization to the DR site."
"If I want to implement an upgrade, I'd like to see how it will be different."
"The cloud is the new challenge and the new opportunity."
"I would like to see an improved Knowledge Base on the web."
"An area that needs improvement is the cloud-based version of the solution because it's designed for on-prem and then transferred to the cloud version."
"Teradata's pricing is quite high compared to Redshift, Synapse, or GCP alternatives."
 

Pricing and Cost Advice

"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
"In this day and age, we want to get things done quickly. So, we go to the AWS Marketplace."
"We are looking for a more flexible cost model for the next version that we use, whether it be cloud or on-premise."
"We had a lot of parties involved when purchasing from the AWS Marketplace. They are very flexible and aggressive in trying to close the deal. They are good at what they have to offer and listening to the customer. It's a two-way street."
"It comes at a notably high cost for what it offers."
"The initial cost may seem high, but the TCO is low."
"The price of Teradata is expensive. However, what they deliver they are outstanding. If you're looking for an inexpensive solution to run a database, this isn't your tool. It's the Ferrari of databases for data warehousing."
"Teradata used to be expensive, but they have been lowering their prices."
"The price of Teradata could be less expensive."
