Enables large teams to collaborate seamlessly with comprehensive integration and strong versioning support
ER/Studio is excellent for large teams; it scales well to teams of over one hundred plus people. It has strong versioning support and can even integrate with third-party versioning tools like GitHub. It has a rich set of integration options with various products in the market. The tool also supports both logical and physical data modeling, and it has out-of-the-box support for data vault methodologies. ER/Studio allows the enforcement of naming conventions, which is beneficial for maintaining standards within the organization.

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

"Straightforward setup."
"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."
"Data lineage tracking: It allows us to identify upstream and downstream systems using data."
"Developing new dimensional models; for the data we're hosting, dimensional modeling is more useful."
"It does the job."
"We are able to document the data lineage and data flows of our data from one system to another."
"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."
"Technical support from Oracle is okay."
"Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation."
 

Cons

"One limitation I have found in ER/Studio is that when you want to make some changes to the table definitions, you have to go item by item. You cannot do it globally. Another issue concerns defining the foreign keys between the different tables. It is a little more tedious in the ER/Studio than in ERrwin. With ERwin it is direct."
"Tech support is a sticking point with me. I am really disappointed in the tech support. We pay for the Platinum level. It takes hours to get a response."
"Sometimes our version is a little unstable. But I think this problem occurs because our version is old."
"I would like to upload, a database with about 3,000 tables. It takes so much time and, finally, it freezes the whole solution so that I actually cannot work with that environment. For the data warehouse, it's fine because I have 20 or 30 tables. It works fine. But, when I reverse-engineer the database with 3,000 tables, it freezes and it's hard to upload and reverse-engineer such environments in ER/Studio."
"I cannot evaluate any areas for improvement at this time."
"It would be helpful if they could create a generic JSON database type, as a target database, rather than a specific one like Mongo."
"It isn't easy to compare the thousands of tables in the model against the database. The tool should improve the synchronization within the large organization"
"They allow functionalities to be released before the full tests for catching and correcting errors are completed."
"The initial setup is complex and time-consuming."
"This platform has issues with stability and performance."
 

Pricing and Cost Advice

"The setup cost may have been around $1500 to $2000."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"The product is pricey."
"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."
"At my previous company using ER/Studio, a database compare took four hours before using the product and 15 minutes after using the product."
"It is priced fairly. It's around the same as erwin and other competitors' costs."
"Pricing is expensive and on the higher-end."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
