IDERA ER/Studio and BMC AMI DevX both compete in the realm of comprehensive database and mainframe management solutions. BMC AMI DevX seems to have an upper hand in mainframe operations due to its robust debugging and change management features, while IDERA ER/Studio stands out in database modeling and collaboration tools.
Features: IDERA ER/Studio provides advanced graphic capabilities, reverse engineering, and strong support for database modeling, coupled with extensive collaboration tools. It also offers sophisticated presentation and flexibility, which are valuable in database environments. BMC AMI DevX is recognized for its debugging and change management functionalities, essential for handling large data and source control. Its adaptability and integration features enhance mainframe operations and management.
Room for Improvement: IDERA ER/Studio faces challenges with server application maintenance and performance issues related to repository speed. Licensing complexity and integration with Active Directory are additional areas for improvement. Users also seek better guidance on business benefits and SQL Server compatibility. BMC AMI DevX requires enhancements in documentation and testing tools, particularly concerning Eclipse integration. Users have reported a steep learning curve and issues with Eclipse compatibility, alongside suggestions for improved disaster recovery planning.
Ease of Deployment and Customer Service: IDERA ER/Studio offers various deployment options, including on-premises and hybrid cloud, though experiences with its technical support vary, prompting some users to prefer premium support. BMC AMI DevX provides on-premises and public cloud deployment with consistently positive reviews for its reliable customer service and technical support, although both could benefit from improved response times for technical issues.
Pricing and ROI: IDERA ER/Studio users encounter challenges with licensing complexity and pricing, but many find the value justifies the cost, leading to good ROI when fully leveraged. Conversely, BMC AMI DevX users appreciate its competitive seat-based licensing, despite some confusion around concurrent user licenses. Its flexible deployment and competitive pricing positively enhance perceived ROI, making both tools valuable when their full range of capabilities are utilized effectively.
I think the hybrid CI/CD integration with existing enterprise DevOps tools in BMC AMI DevX is very good.
BMC AMI DevX's technical support responds very well and takes all cases seriously.
Every time I open a case, I get an immediate response.
The documentation is more robust than Erwin's, but their interface is not as intuitive.
There is plenty of documentation available online for assistance, making it straightforward to address any issues.
From my perspective, I haven't seen BMC AMI DevX struggle in terms of workloads where it needs to be scaled up or scaled down.
BMC AMI DevX Code Pipeline runs on one LPAR, and no matter where someone is in the world, they have to use it on that LPAR.
BMC AMI DevX is absolutely scalable.
It scales well to teams of one hundred plus people.
BMC AMI DevX is very stable for a modern application processing huge workloads.
I would rate BMC AMI DevX as a stable solution that I have been using for years and find working fine.
Erwin is a very stable product.
I have to put my cursor on the field and tap it to bring focus there, or use the tab key multiple times to get to a field on the screen.
The startup problem is the one that definitely needs to be addressed.
To improve BMC AMI DevX, consideration should be given to cloud-style provisioning and development models, as well as integration of more AI capabilities.
Both Erwin and ER/Studio do not have AI or machine learning features for automation.
Erwin's metadata management is better in how it handles data.
The setup cost may have been around $1500 to $2000.
In terms of pricing, ER/Studio is slightly more expensive compared to Erwin, by about five to ten percent.
BMC AMI DevX's tools have affected my developers' productivity and efficiency by helping with the speed.
The CI/CD offering allows integration of quality checks and unit test processes into the pipeline, which improves compliance and enhances productivity, enabling developers to focus on development while the pipeline automates integration.
With ISPW, developers can back out the entire release or entire package.
When we built an application, it facilitated the development process by providing the skeleton of the application and the foundation for functions.
It has strong versioning support and can even integrate with third-party versioning tools like GitHub.
IDERA ER_Studio does a lot more and performs model comparison much better than Erwin.
