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

"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."
"I think it's the best due to pricing and good overall support."
"We can track changes to our data models and tie those changes back to specific tasks or efforts that we identify."
"We use it either to help an organization understand what data it has got or to design a database."
"One example is the use of the product to make extracts and split databases, and we were selling parts of the company to other regions of other companies, and it made the process more efficient and faster and less costly."
"We have been able to quickly create models for our enterprise-wide databases, even when some of them are third-party databases."
"Using this product has improved the way we maintain our models because they have a place where we can keep all of them, and they can be viewed using the web interface."
"We use the solution to create data models which describe our company's data architecture"
"In my experience, while working on customers’ solutions where performance is a key requirement, along with robustness and stability needs, I have always found Oracle Coherence as the best solution for integrating with different Oracle products and caching data for application-specific needs."
"Coherence allows linear on-line scalability across multiple commodity servers."
"Basically reducing response times to extremely small latencies in their apps."
"Coherence has improved response times for queries of sizeable data sets, and by allowing for data distribution and replication through clustering, it improves the reliability of information systems."
"Technical support from Oracle is okay."
"Coherence has helped us to drastically reduce the request time of our web applications."
"High availability, distributed calculation features, and WebLogic integration are the most valuable features to me."
"The product is great, simple, and easy to use and integrate."
 

Cons

"The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare)."
"The repository causes continuous problems, as it's slow and sometimes crashes."
"The print facility is a little lacking."
"I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's."
"There have been some issues with performance, and there are some issues with inconsistencies."
"We would always like to see Repository performance improve, checking in and checking out."
"We receive these new functionalities, and sometimes we start to test them and we find errors that we need to correct by talking with tech support."
"Installation of the product itself is straight forward although the licensing process is awkward and confusing at best."
"It is very easy to set up a basic topology, but hard to configure and tune to make it really work."
"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."
"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."
"The initial setup is complex and time-consuming."
"Data transfer performance over geographical locations. Oracle database has better performance compared to Coherence when accessed from different regions."
"Product is too expensive and support is poor. There are better products."
"We have encountered the occasional minor bug and very occasional more serious bug."
"The cross-site or cross-data center replication seems slow. This can be improved."
 

Pricing and Cost Advice

"Pricing is on point, but do your due diligence - not every developer needs the tool."
"As an individual user, the renewal is a little costly."
"The product is pricey."
"The price of this product is okay."
"The solution’s pricing is high."
"Pricing is expensive and on the higher-end."
"At my previous company using ER/Studio, a database compare took four hours before using the product and 15 minutes after using the product."
"I feel the product's pricing is a good value."
