Find out what your peers are saying about LeanIX, Sparx Systems, erwin by Quest and others in Enterprise Architecture Management."The data lineage feature is very valuable."
"The logical model gives developers, as well as the data modelers, an understanding of exactly how each object interacts with the others, whether a one-to-many, many-to-many, many-to-one, etc."
"Any tool will do diagramming but I think the ability to put the stuff up in a graphical fashion, then think about it, and keep things consistent is what's valuable about it. It's too easy when you're using other methods to not have naming consistent standards and column consistent definitions, et cetera."
"The solution is excellent in providing a visual representation of a database and can generate DDL for implementing changes. We use DDL for logical purposes to review with business people, ensuring they have the required fields for processing. We also use it as a data dictionary for the physical data model to understand all the purposes of the terms. This helps us map the logical and physical terms with the business definition to understand our data."
"The most valuable feature is the physical or visual representation of the database, showing the tables, the columns, the foreign keys, and the ability to generate DDL, so you can physically implement databases."
"What has been useful, I have been able to reverse engineer our existing data models to document explicitly referential integrity relationships, primary/foreign keys in the model, and create ERDs that are subject area-based which our clients can use when working with our databases. The reality is that our databases are not explicitly documented in the DDL with primary/foreign key relationships. You can't look at the DDL and explicitly understand the primary/foreign key relationships that exist between our tables, so the referential integrity is not easily understood. erwin has allowed me to explicitly document that and create ERDs. This has made it easier for our clients to consume our databases for their own purposes."
"The solution's ability to compare and synchronize data sources with data models is fantastic. We use it for that on a regular basis to make sure that changes haven't been made to the database outside of the modeling process. I can take existing databases and reverse engineer them and understand their structure within 15 minutes. If I didn't have Data Modeler it would take hours. It increases our productivity and helps in understanding our legacy application."
"It allows us to create logical data models. We can represent a database model in business terms, which is very useful for us."
"Traceability is a fantastic feature."
"The solution's model mark could be better because it crashes sometimes."
"Some Source official systems give us DDLs to work with and they have contents not required to be part of the DDL before we reverse engineer in the erwin DM. Therefore, we manually make changes to those scripts and edit them, then reverse-engineer within the tool. So, it does take some time to edit these DDL scripts generated by the source operational systems. What I would suggest: It would be helpful if there were a place within the erwin tool to import the file and automatically eliminate all the unnecessary lines of code, and just have the clean code built-in to generate the table/data model."
"It would be nice to have it on the Linux platform, not just Windows. If they can support Linux, there would be a huge market for it."
"erwin is not as robust as a data warehousing project I've been on in the past."
"The Bulk Editor needs improvement. If you had something that was a local model to your local machine, you could connect to the API, then it would write directly into the repository. However, when you have something that is on the centralized server, that functionality did not work. Then, you had to export out to a CSV and upload up to the repository. It would have been nice to be able to do the direct API without having that whole download and upload thing. Maybe I didn't figure it out, but I'm pretty sure that didn't work when it was a model that sat on a centralized repository."
"The solution's reporting side needs to be improved."
"I would like to see the reporting capabilities be more dynamic and more inclusive of information. The API is very sparsely understood by people across the user community."
"I'd really like to see the PDF function become available. It would make my life much easier than what it is at the moment because whenever I need to collaborate with people that do not have erwin, I have to go through the wonkiness of going to Word and then save it from Word into PDF. There's a lot of differences between erwin 4.4 and 2020."
"The algorithm is outdated and should be upgraded."
