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 are able to document the data lineage and data flows of our data from one system to another."
"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."
"It's a great tool for modeling and I'm generally very happy with its features."
"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."
"Modeling with Data Architect: We can quickly reverse-engineer a database from an existing database or create a model from scratch."
"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."
"My overall rating for the solution is ten out of ten."
"Overall, the product is very powerful and versatile for the task it's designed to do."
"Oracle Coherence improved site performance and the customer experience."
"Portable object format (POF serialization) allows objects to be serialized and deserialized between Java and .NET so the two platforms can exchange data seamlessly."
"Coherence allows linear on-line scalability across multiple commodity servers."
"It can handle an extremely high volume of data."
"Space consumption is much less."
"This product helped our organization to focus on implementing business logic without worrying about scalability on user loads of huge data queries."
"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."
"Coherence absolutely outperforms others in terms of scalability, reliability, and performance."
 

Cons

"The only thing I had an issue with was licensing, and the support was very good."
"I would like to see better documentation/help for the Data Architect tool. Creation of tutorials would be nice, as there are some features which are not as clearly defined as they should be."
"I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's."
"The repository causes continuous problems, as it's slow and sometimes crashes."
"It would be helpful if they could create a generic JSON database type, as a target database, rather than a specific one like Mongo."
"The visual presentation is a little too colorful and seems that it is dumbed down."
"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."
"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."
"Cluster management tools that are independent of WebLogic. Dynamic cluster config rollout and rollback."
"Monitoring API needs to be improved and needs to be user friendly. Also, the error and exception handling is not that great as it can be difficult to debug issues."
"Product is too expensive and support is poor. There are better products."
"Customer service: Five out of 10."
"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."
"I would like to see a more modern API like Hazelcast or Infinispan."
"The price is high. I believe there should be a cheaper version for only the caching solution."
 

Pricing and Cost Advice

"I use the product's trial version."
"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."
"The product is pricey."
"The setup cost may have been around $1500 to $2000."
"Pricing is expensive and on the higher-end."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"The price of this product is okay."
