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

"The data modeling and reverse engineering features are most important to us."
"We have a database design group of about 15 people. The Repository enables multiple people to work on the same model at the same time. We have fully integrated models, so we have one model for the enterprise data warehouse, one model for MDM, with a lot of sub-models in these things. People work on different parts of the model at different times. So the repository enables us to share the models, and keep track of what everybody is working on."
"It's a great tool for modeling and I'm generally very happy with its features."
"It's much easier to develop the database structure and change it on the fly, rather than doing it manually in SQL Server itself, which saves time."
"It's much easier to develop the database structure and change it on the fly, rather than doing it manually in SQL Server itself. That saves time."
"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 interface is really simple to use and it allows me to pick and choose which tables I want to reverse engineer."
"It's easy to model and has a user-friendly interface. I like the team portal because, once we upload, the entire team can see the model."
"It can handle an extremely high volume of data."
"It helped us to cache the data in memory and improved performance by 10x."
"Space consumption is much less."
"Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation."
"Introducing a data grid, we moved from a vertically scalable solution to full scalability."
"I have used Oracle Coherence for more than 10 years, from version 3.5 through 12.1.2.1."
"The biggest improvement is in speed - everything is faster from record retrieval to workflow processing."
"Coherence absolutely outperforms others in terms of scalability, reliability, and performance."
 

Cons

"when there are some links to the external databases, if this database is not structured it is not uploaded. It gives me errors and I cannot see the view that was created on this structure and I cannot change those views, even manually. It skips the views. I have to ignore those views. I cannot re-upload them because it gives me an error."
"The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare)."
"They allow functionalities to be released before the full tests for catching and correcting errors are completed."
"Installation of the product itself is straight forward although the licensing process is awkward and confusing at best."
"The solution is not so strong at creating modeling views and database views."
"The only thing I had an issue with was licensing, and the support was very good."
"I cannot evaluate any areas for improvement at this time."
"The print facility is a little lacking."
"Product is too expensive and support is poor. There are better products."
"Customer service: Five out of 10."
"Complexity being a huge contributor to risk/cost for projects, I am more likely to use other products as a result."
"Initial setup was complex. We wrote a lot of wrapper code around the Coherence libraries in order to make it easier for the developer."
"Reloading really takes a lot of time."
"We have nodes failing all the time, especially because of timeouts caused by node synchronization, but occasionally there are also memory-related errors."
"Technical support is 3 or even 2 out of 10. Working directly through an account rep or a contact on Coherence dev team helps a lot."
"OSB could be tuned to do things like Apigee."
 

Pricing and Cost Advice

"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."
"The price of this product is okay."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"The solution’s pricing is high."
"As an individual user, the renewal is a little costly."
"The product is pricey."
"It is priced fairly. It's around the same as erwin and other competitors' costs."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
