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

"The thing two things that I like most about Oracle Database are its scalability and performance."

"The support is always very helpful and responsive."

"The solution is definitely very good for our consultancy on payroll and human resource."

"The solution is scalable."

"The most valuable features of this solution are the cost optimizer and partition exchanges."

"Oracle is a stable product and we plan to continue implementing it."

"The most important features of Oracle Database are ease of use and high reliability. I also love the dynamic PL/SQL feature, which I use to generate custom and ad hoc reports."

"It's powerful and fast, and the backup system is wonderful."

More Oracle Database pros

"There are several features of Teradata that I like. One of the most basic is the indexes. I also like that it provides lower TCO. It also has the optimizer feature which is a good feature and isn't found in other legacy systems. Parallelism is also another feature I like in Teradata because when you are running or hosting on multiple systems, you have this shared-nothing architecture that helps. Loading and unloading in Teradata are also really helpful compared to other systems."

"Improved performance of ETL procedures, reporting."

"Teradata has good performance, the response times are very fast. Overall the solution is easy to use. When we do the transformation, we have all of our staging and aggregation data available."

"It's very mature from a technology perspective."

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

"The feature that we find most valuable is its ability to perform Massive Parallel Processing."

"The data mover is valuable over the last two years as it allows us to achieve data replication to our disaster recovery systems."

"Things have started moving faster in my company, such as data retrieval happens more quickly."

More Teradata pros

Cons

"The previous version was a little clunky."

"Oracle could improve the finance system."

"It takes a significant amount of time after submitting an initial SR with Oracle Tech Support before your case reaches a technical expert with whom you can actually work on the issue resolution. Before that, you have to deal with people who are not experts."

"Since the solution is from Oracle it tends to be complex when trying to integrate with other solutions."

"The product must provide an autonomous database."

"It should have flexible licensing across different platforms. It has got different licensing models for Intel Power and SPARC servers."

"When it comes to Oracle, the only complaint that I have is their support. For business-critical cases, finding support is a little bit difficult because of the timezone difference. They should provide faster support to resolve issues on time."

"They could improve the scalability a bit. There are other options that are more scalable, for example."

More Oracle Database cons

"The tool's flexibility and capacity for expansion are areas of concern where improvements are required."

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

"Data ingestion is done via external utilities and not by the query language itself. It would be more convenient to have that functionality within its SQL dialect."

"Teradata needs to pay attention to the cloud-based solution to make sure it runs smoothly."

"It's primarily designed for big projects and therefore, the pricing is pretty high. It's not suitable for smaller companies."

"GUI of administrative tools is really outdated."

"The solution needs improvement in its stability, support and pricing."

"We tried to use case Teradata for a data warehouse system, but we had some problems in relation to the Teradata system, CDC tools, and source databases. We were unable to transfer data from HPE Integrity mainframe to Teradata."

More Teradata cons

Pricing and Cost Advice

"The price of the solution could improve."

"Oracle Database could make the documentation better around licensing. The way you have to access software from Oracle is difficult. You have to go through the licensing lawyer to understand what your reach is when you subscribe to one unit. I wish the documents were easier to understand for everyone. This is a problem I have always grappled with and it's not changed. Having clarity is even more important now that I'm thinking of having a hybrid setup for the database in the cloud for high availability."

"The Oracle Database licensing price could be less expensive. We pay annually for the use of the solution."

"It is quite expensive."

"The license cost need to be optimized. The licensing cost is very high compared to other RDBMS."

"Seeing as a lot of our applications use Oracle, our team has been able to negotiate a better deal."

"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."

"There is a license required for this solution and it is a little expensive."

More Oracle Database pricing and cost advice

"I rate the product price a nine on a scale of one to ten, where one is cheap and ten is expensive."

"Teradata used to be expensive, but they have been lowering their prices."

"The cost of running Teradata is quite high, but you get a good return on investment."

"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."

"The initial cost may seem high, but the TCO is low."

"It is still a very expensive solution. While I very much like the pure technological supremacy of the software itself, I believe Teradata as a company needs to become more affordable. They are already losing the market to more flexible or cheaper competitors."

"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."

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