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."
"The interface is really simple to use and it allows me to pick and choose which tables I want to reverse engineer."
"It has a wealth of time-savers and features that are extremely useful."
"It does the job."
"Valuable features include the ability to visually represent what the database tables are going to look like and their relationships. Also, the ability to document the definitions of the tables and the columns that are in a table so that we can communicate what the data is and how it should be used."
"ER/Studio is excellent for large teams; it scales well to teams of over one hundred plus people."
"The most valuable feature is data modeling, primarily, because it's something that has been lacking in our systems development for 20 years."
"We found a lot of duplication, a lot of non-conformity in the way our databases were designed. By identifying these situations, we're able to go back in and try to create a more standardized solution."
"The Customer Facing Application response time has been improved 95%."
"A single logical cache scattered across various geographies ensured we had only one cache to look against (location transparency) at the same time, ensuring high availability."
"Portable object format (POF serialization) allows objects to be serialized and deserialized between Java and .NET so the two platforms can exchange data seamlessly."
"Basically reducing response times to extremely small latencies in their apps."
"Space consumption is much less."
"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."
"It can handle an extremely high volume of data."
 

Cons

"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."
"There have been some issues with performance, and there are some issues with inconsistencies."
"They allow functionalities to be released before the full tests for catching and correcting errors are completed."
"This version does not properly generate SQL Server computed columns; future versions do this."
"The model diagram because very clumsy when you save it on the team server and the models are very big."
"The solution's reporting could be improved because the report writer is terrible."
"The visual presentation is a little too colorful and seems that it is dumbed down."
"Tech support hasn't been as good lately as it was in the past. It is down to average."
"Would be good if the initial setup was easier."
"Coherence failed to live up to its SLA by not being able to recover but getting into a state where new nodes were created when the old ones were still there but for some reason no longer recognized as being part of the cluster."
"Reloading really takes a lot of time."
"The product is the best, but it's absurdly expensive because licensing is according to the number of CPUs."
"In my experience, I did find it challenging to use this product when namespace prefixes on the resulting XML object was a requirement."
"It is very expensive. It might not work well for small business people."
"It has become very heavy along with the price for Oracle's integrated product as a fusion middleware."
"Due to the licensing prices, we are looking for other solutions as an alternative to Coherence."
 

Pricing and Cost Advice

"It is priced fairly. It's around the same as erwin and other competitors' costs."
"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."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"Pricing is expensive and on the higher-end."
"The setup cost may have been around $1500 to $2000."
"I use the product's trial version."
"As an individual user, the renewal is a little costly."
"I feel the product's pricing is a good value."
