The data catalog feature helps define data structures without storing data
The data catalog feature is valuable as it helps define data structures without storing data. Denodo's ability to connect to multiple data sources and perform extract-transform-load (ETL) operations on the fly is noteworthy. It supports API usage to call and present data in JSON or Tableau format without visualization capabilities.
Jason Hale - PeerSpot reviewer
Intuitive interface and documentation make it simple to build jobs and APIs and logging helps pinpoint and resolve issues quickly
Talend is doing a lot of work at the moment, and it's not there yet, but the whole platform could be managed in a SaaS-type environment. You still need to have the Studio running on a virtual desktop or a PC. They will get to be able to do the whole thing inside your browser, so you don't need to install anything locally. It's down the track, and it's the nirvana that we were looking for in Boomi. But the biggest challenge they have is that the platform is so focused on the Studio for all of its development. They'll probably get there, but they have such a mature Studio client that it's a huge amount of work to get all of that functionality into a browser or SaaS platform. That's pretty much the biggest flaw with the Talend environment—being reliant on the Studio, which needed to be on a local machine. The only other thing is that you have to integrate into an API gateway. We're in Azure, so we use Microsoft Azure Gateway. It doesn't come with its own gateway, which is another sort of big plus side that we saw in Boomi. Talend isn't quite there yet with the API gateway. Other than that, it's bloody hard to find something because it just seems to be all good.

Quotes from Members

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

Pros

"The most valuable feature is the performance. Denodo is very useful, especially in this huge pharma environment. I've found that older SAP solutions were very tightly coupled to each other, which resulted in data restrictions. Getting data from different sources was tough and tedious. Compared to these old solutions, Denodo is very easy to work with for the analytical team. Now that we've implemented this virtualization layer, we are capable of getting the data very smoothly. We implemented a very small unit, but the performance and integration have been very good."
"Overall, I would rate Denodo a nine out of ten."
"Denodo is very stable."
"Denodo's best features are its performance, easy data transformation, and the job scheduler."
"The most valuable feature is Data Catalogs."
"The data abstraction is the most valuable feature."
"The logical data warehouse functionality is fantastic. It truly stands out. The ClearOptimizer and Virtual Cache are great features. They work together seamlessly to optimize performance."
"The most valuable feature of Denodo is its uniformity of self-site data access types, which allows it to connect to almost any storage technology and feed it transparently."
"There are many architectures: hybrid, cloud, and on-prem."
"The standout feature for me is the user-friendly nature of the components."
"Talend is safe to use because it is very restrictive. It is easy to use when one learns how to manipulate data with SQL."
"The best thing I have found with Talend Open Studio is their major support for the lookups."
"Talend can connect to multiple data sources, including relational data sources, ERP, CRM, and others."
"Talend Open Studio is easy to create jobs. We use the basic functionality and it is very good."
"Open Studio's best features are that it's user-friendly, even for beginners, and very easy to implement."
"The most valuable features of Talend Open Studio are customization and integration."
 

Cons

"The cache configuration is more complicated."
"I would like it if we could pull the data model or export the data model because Denodo has, based on how you build, something called associations. The data model gets very confusing when you go look at it. It depends on how you define it, but it's really huge. I wish there was a way to export it into Visio. It could be that they already have a way to do it, and I don't know, but it would be much easier for the architects and even for the developers to look at it than scrunching it into the screen and expanding every small portion of it. If there was an easy way to export the Denodo model into another modeling tool and view it, it would be great."
"Denodo has some difficulty supporting large numbers of records."
"We would like this solution to be more universally user-friendly. At present it is really only aimed at IT specialists."
"Monitoring event logs can be improved. In the older version, there was a monitoring schedule to get event reports and properly audit the reports. In the newer version, it is not there, and we have to manually configure data and audit events."
"Lacks integrations with AWS, GCP and the like."
"Tasks such as conversion of a date format or conversion of a number format that can be done in a very easy way in different languages, like SQL or Oracle, are not so easy to do in Denodo. For example, if you want to convert a date from one format to another, in Oracle it's pretty easy; in Denodo, however, it requires so many lines of code. Simple things that can be done very quickly in other database languages require more lines of code in Denodo."
"It would be beneficial to make sure that the team that will be using Denodo has some kind of training on how to use the product at least a month beforehand, and there could even be some kind of feedback or Q&A sessions to go along with the training. If Denodo were able to provide this kind of training, it would be very helpful to users in insurance and banking companies because the staff are typically older and not always technically-minded."
"The only other thing is that you have to integrate into an API gateway. We're in Azure, so we use Microsoft Azure Gateway. It doesn't come with its own gateway, which is another sort of big plus side that we saw in Boomi. Talend isn't quite there yet with the API gateway."
"The security features could be improved."
"The stability of the solution could improve when running jobs. There can be errors when running projects but in the end, it works well and the errors do not impact the result."
"In terms of what can be improved, the scheduling is not there in the sister version, while it is there in the cloud one, which is a paid version. If all kinds of scheduling could be available on the Open Studio that we generally use and practice on, that would be great. The scheduling of the data migration is currently not available in the sister version of Talend Open Studio that we are working on. It is available in the advanced version of the Talend. This is the one thing that can be improvised."
"Inter-version compatibility is a problem, and migration projects between versions are required."
"It needs better installation configuration for other databases. Although the installation allows you to select another database, this doesn't mean that all connection points in the application point to the database selected. You actually need to do a search through the entire install to locate the configuration settings and change them."
"The pricing could be lower. They should work to make it more affordable."
"We need more components to be more efficient. We use a lot of components, such as Salesforce, and it's not easy to use. There's are minor bugs and it's not easy to use some of the features."
 

Pricing and Cost Advice

"Denodo provides a lightweight 30-day free trial, but when we do courses on top of it, it costs $150 for each person."
"The licensing charges for this solution are payable annually."
"For us, the cost has been okay. Also, there are no additional costs; it's just the standard licensing fee."
"Depending on the size of the client you want to work with, it can be prohibitively expensive at times."
"I am not super familiar with the pricing, but so far, it seems good. We have been happy. We haven't seen any problems. The only time we had to pay extra was during the upgrade. We didn't upgrade at the time they told us to upgrade, and we had to pay extra to keep the service. They had stopped the support for the older version and moved to the newer version. It was not their fault. It was our fault because we didn't get on board quickly."
"The pricing is pretty good, and I would rate it at four out of five."
"There is an express edition and a licensed enterprise edition."
"The cost for Denodo is in line with other similar products."
"Open Studio has a basic license and additional costs for services, including customer support and technical assistance."
"Talend Open Studio costs about 11,000 a year."
"For Talend Open Studio, there is a need to make yearly payments towards the licensing cost. Talend Open Studio is a bit expensive, in my opinion."
"It is an open-source tool which means it is a free solution."
"I am using the open-source version and it is free."
"Price could be lower. It is getting too expensive when compared to some other solutions, which is actually a little bit concerning."
"Talend Open Studio is priced too high."
"The cost, particularly in Africa, is quite high."
