Improved data modeling has reduced system footprint and strengthened finance workflows
I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's. Erwin's metadata management is better in how it handles data. There is a lot more user involvement in managing the metadata, primarily because in IDERA ER_Studio, the logical and physical models are separately defined in the same file, so you have to map them every single time. In Erwin, it has a unified structure, so if you make a change in the logical model, it automatically shows up in the physical model. You have to go through a couple of steps in the IDERA model to make sure everything has moved over. While that is not that inconvenient when you are actually doing development, as far as metadata management, that is prone to things getting dropped and missed. The collaboration tools in IDERA ER_Studio are adequate, but I think with Erwin, there is more of an opportunity for things to crash. Changes can be merged in IDERA more fluidly; however, the locking and sharing are a little bit more defined in Erwin. I think the learning curve for Erwin might be easier than IDERA ER_Studio, especially with connecting to different models and systems.

Facilitating real-time business insights with enhanced data querying
Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation. These features facilitate querying data with multiple keys rather than just a single key. Its real-time data processing capabilities provide insights for business decisions with up-to-date information.

Quotes from Members

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

Pros

"I think it's the best due to pricing and good overall support."
"IDERA keeps up with the versions of Oracle and SQL Server that I'm using. I mostly use SQL Server and when there are new features, a new type of index, for example, IDERA also includes them in upgrades of the data modeling tool."
"The most valuable features are... those that enable me to represent the database to the development community and the business users."
"The most important features are logical and physical models that we can compare and develop. Also, the Data Dictionary can be created out of your studio. Finally, database schemas help understand the logic that's behind the scene, behind the SQL tables. Especially when there are a lot of them, the schemas help everyone understand the business processes."
"ER/Studio is good. It is really user-friendly and you can start without much training."
"With both onshore and offshore development teams working 18x5 days, it is an easy way to control check-in's while also maintaining schema views."
"Before this tool, just managing the changes and publishing the models to the users became very cumbersome, and this tool has simplified our day-to-day tasks a lot."
"Our primary use case of this solution is to design our database."
"It helped us to cache the data in memory and improved performance by 10x."
"We are storing information from one of our applications; this allows us to answer requests in milliseconds, while the application would take seconds to answer requests from clients."
"Other technologies don’t allow the same level of scale and compute capability, while providing rigorous resilience and security underpinnings."
"The product is stable and solid."
"This product helped our organization to focus on implementing business logic without worrying about scalability on user loads of huge data queries."
"Introducing a data grid, we moved from a vertically scalable solution to full scalability."
"Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation."
"Basically reducing response times to extremely small latencies in their apps."
 

Cons

"Documentation tends to range from pointless to incomprehensible."
"Tech support hasn't been as good lately as it was in the past. It is down to average."
"We did have a big issue when we upgraded to the 2016 version. The Team Server portion never did quite install correctly, and/or the database was corrupted, and we never figured it out."
"I'd like the ability to debug the errors ourselves instead of having to call them. There are certain types of errors that, I wouldn't say they come up regularly, but when you have an error it is very often the same type of error. Knowing that it's a Type III or Type I, it would be nice to have some kind of debugging facility for us to use to find out where the problem that threw that error occurs. That would be a really cool feature."
"There was no specific mention of areas needing improvement."
"The repository causes continuous problems, as it's slow and sometimes crashes."
"Diagram versioning is not very intuitive Data Dictionary Bindings is not very intuitive"
"There have been some issues with performance, and there are some issues with inconsistencies."
"Due to the licensing prices, we are looking for other solutions as an alternative to Coherence."
"Cluster management tools that are independent of WebLogic. Dynamic cluster config rollout and rollback."
"I would like to see a more modern API like Hazelcast or Infinispan."
"They could make the configuration management easier."
"It is very expensive. It might not work well for small business people."
"Oracle Coherence has considerable operational risks."
"Configuration is too complex."
"We have encountered the occasional minor bug and very occasional more serious bug."
 

Pricing and Cost Advice

"The product is pricey."
"The price of this product is okay."
"The process of licensing could be much simpler, from our experience."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
"It is priced fairly. It's around the same as erwin and other competitors' costs."
"Pricing is expensive and on the higher-end."
"On a scale of one to ten, where one is bad and ten is good, I would rate the licensing cost as a seven or eight. It's not too expensive for us."
"Pricing is on point, but do your due diligence - not every developer needs the tool."
