Offers seamless integration capabilities and performance optimization features, including extensive indexing and advanced tuning capabilities

We created and constructed the warehouse. We used multiple loading processes like MultiLoad, FastLoad, and Teradata Pump. But those are loading processes, and Teradata is a powerful tool because if we consider older technologies, its architecture with nodes, virtual processes, and nodes is a unique concept. Later, other technologies like Informatica also adopted the concept of nodes from Informatica PowerCenter version 7.x. Previously, it was a client-server architecture, but later, it changed to the nodes concept. Like, we can have the database available 24/7, 365 days. If one node fails, other nodes can take care of it. Informatica adopted all those concepts when it changed its architecture. Even Oracle databases have since adapted their architecture to them. However, this particular Teradata company initially started with its own different type of architecture, which major companies later adopted. It has grown now, but initially, whatever query we sent it would be mapped into a particular component. After that, it goes to the virtual processor and down to the disk, where the actual physical data is loaded. So, in between, there's a map, which acts like a data dictionary. It also holds information about each piece of data, where it's loaded, and on which particular virtual processor or node the data resides. Because Teradata comes with a four-node architecture, or however many nodes we choose, the cost is determined by that initially. So, what type of data does each and every node hold? It's a shared-no architecture. So, whatever task is given to a virtual processor it will be processed. If there's a failure, then it will be taken care of by another virtual processor. Moreover, this solution has impacted the query time and data performance. In Teradata, there's a lot of joining, partitioning, and indexing of records. There are primary and secondary indexes, hash indexing, and other indexing processes. To improve query performance, we first analyze the query and tune it. If a join needs a secondary index, which plays a major role in filtering records, we might reconstruct that particular table with the secondary index. This tuning involves partitioning and indexing. We use these tools and technologies to fine-tune performance. When it comes to integration, tools like Informatica seamlessly connect with Teradata. We ensure the Teradata database is configured correctly in Informatica, including the proper hostname and properties for the load process. We didn't find any major complexity or issues with integration. But, these technologies are quite old now. With newer big data technologies, we've worked with a four-layer architecture, pulling data from Hadoop Lake to Teradata. We configure Teradata with the appropriate hostname and credentials, and use BTEQ queries to load data. Previously, we converted the data warehouse to a CLD model as per Teradata's standardized procedures, moving from an ETL to an EMT process. This allowed us to perform gap analysis on missing entities based on the model and retrieve them from the source system again. We found Teradata integration straightforward and compatible with other tools.

Quotes from Members

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

Pros

"Optimization of databases, RAC, Data Guard Replication with Data Guard and RAC Database are the best features."

"The product provides high availability."

"It is one of the most reliable database systems."

"The tool supports a large volume of transactions compared to other databases we've used. One feature that had a significant impact is Oracle Data Integrator. It allows us to transfer data from the enterprise database to the data warehouse. This is useful for creating different data sets for finance teams and other departments."

"The solution has great security."

"We find technical support to be very responsive. They briefly describe everything on phone and we handle the operations. I'd say we've been more than satisfied with their level of service. They're quite helpful and knowledgeable."

"It does what I want it to do. It has got a lot of features. Anytime I need a feature, I am able to find it in Oracle Database. It has never happened that I found a feature in any other database, but I was not able to find it in Oracle."

"It's very reliable."

More Oracle Database pros

"It's stable and reliable."

"The most valuable feature of Teradata is security. It runs on Unix and Linux platforms which provide better security."

"Building a data warehouse with Teradata has definitely helped a lot of our downstream applications to more easily access information."

"The data processing, clustering, and distributed computing are impressive."

"The functionality of the solution is excellent."

"It has massive parallel processing ability to do large amounts of concurrent querying."

"It has a solid set of tools and consulting services."

"The most valuable feature is the ease of running queries."

More Teradata pros

Cons

"The compression does not give much value-add or provide performance benefits as was highlighted."

"The user interface could be better."

"The product's price can be lower since it is a bit of an expensive solution."

"The usage and security are okay for Oracle Database, but its pricing is more expensive when compared to its competitors."

"The licensing model is complicated and could be improved."

"The initial setup is a bit complex."

"This product would be improved with Support Services for more production access."

"Oracle support is helpful, and they resolve all our issues, but sometimes the response to our clients isn't as prompt as we'd like."

More Oracle Database cons

"I would like to see an improved Knowledge Base on the web."

"The current operational approach needs improvement."

"It could use some more advanced analytics relating to structured and semi-structured data."

"Teradata needs to expand the kind of training that's available to customers. Teradata only offers training directly and doesn't delegate to any third-party companies. As a result, it's harder to find people trained on Teradata in our market relative to Oracle."

"There is a need to improve performance in high transaction processes, as well as the reporting system."

"Since I was working on the very basic, legacy systems, the memory thing was always a challenge. If Teradata is moving to the cloud, the space constraint or the memory issue that my company generally faces will eventually resolve, in time. What I'd like to see in the next release of Teradata is that it becomes full-fledged on the cloud, apart from better connectivity to various systems. For example, if I have to read or include a Python script, if I write some basic codes, I should be able to read even unstructured data. I know that it's not supported even in Snowflake, but at least semi-structured data support, if that can be a little more enhanced, that would be good."

"It is hard for some of our users to set up rules for cleansing and transforming data, so this is something that could be improved."

"The reporting side wasn't very good in the past, but with the latest versions, it's getting better. Still, the friendliness of the PDC reporting and functionality needs to be improved."

More Teradata cons

Pricing and Cost Advice

"There are licensing costs."

"The tool's pricing is high and yearly."

"The main issue where I feel that Oracle still has a problem is with the licensing. Licensing is still expensive and the reason why today most startups use other, cheaper databases. Those other databases are much less sophisticated than Oracle."

"It's expensive. I would say that it is more expensive than other competing products."

"The price of the solution could improve."

"It has an annual subscription. It is an Oracle solution, so it is a bit expensive, but that's fine."

"Oracle is also very expensive."

"There is a license required to use Oracle Database."

More Oracle Database pricing and cost advice

"In this day and age, we want to get things done quickly. So, we go to the AWS Marketplace."

"Teradata is currently making improvements in this area."

"Teradata pricing is fine, and it's competitive with all the legacy models. On a scale of one to five, with one being the worst and five being the best, I'm giving Teradata a three, because it can be a little expensive, when compared to other solutions."

"The tool costs about 30,000 euros a month, while Azure Synapse SQL only costs 10,000."

"Price is quite high, so if it is really possible to use other solutions (e.g. you do not have strict requirements for performance and huge data volumes), it might be better to look at alternatives from the RDBMS world."

"In the past, it turned out that other solutions, in order to provide the full range of abilities that the Teradata platform provides plus the migration costs, would end up costing more than Teradata does."

"Teradata is not cheap, but you get what you pay for."

"Teradata's licensing is on the expensive side."
