We performed a comparison between erwin Data Catalog by Quest and IBM InfoSphere DataStage based on real PeerSpot user reviews.
Find out what your peers are saying about Informatica, Alation, SAP and others in Metadata Management."When you combine it with data lineage, every time you need to make a change, it allows you to do impact analysis on any changes and then connect to the end-users or data stewards so that they can be aware that a change is coming. That's one of the main benefits we use it for."
"The data catalog feature is pretty good."
"Compared to other ETL tools, DataStage has excellent debugging and development capabilities. And the availability of connectors, even though we sometimes have to opt for specific ones. Also, the availability of patches is good."
"As a data integration platform, it is easy to use. It is quite robust and useful for volumetric analysis when you have huge volumes of data. We have tested it for up to ten million rows, and it is robust enough to process ten million rows internally with its parallel processing. Its error logging mechanism is far simpler and easier to understand than other data integration tools. The newer version of InfoSphere has the data catalog and IDC lineage. They are helpful in the easy traceability of columns and tables."
"We like the flexibility of modeling."
"We are mostly using transmission rules. It has a lot of functions and logic related to transmission. It is a user-friendly tool with in-built functions."
"In IBM DataStage, the Transformer is the most valuable feature for me. It enables me to apply complex transformations, generate the gateway key, and map source tables into the session table."
"The solution has improved the time it takes to perform tasks related to batch applications."
"I am impressed with the tool's ETL tracing."
"The most valuable feature of the solution is the ability to incorporate very complex business rules in Data Stage."
"There are always ways to improve things. For example, we can use AI to be able to find out something. When we are typing something, if we don't know the exact term, Artificial Intelligence would be useful to find terms that are phonetically or syntactically similar. Instead of having to type in the exact name, they can provide those in the list. So, they can provide AI support for the search because when you have thousands and thousands of terms, it is hard to remember all the names."
"There is room for improvement with respect to the connector and how to connect to the structured and unstructured database."
"In the future, I would like to see more integration with cloud technologies."
"I'd like to be able to do more with the data and metadata, including copy and pasting, et cetera."
"I really like this tool, but the administration should be on the same client application because a lot of administration features are not on the client-side, and they usually need to have administrative access. It's quite complicated to force IT teams to have separate administrative access from the developers."
"The troubleshooting guide is very bad."
"The pricing should be lower."
"The documentation and in-application help for this solution need to be improved, especially for new features."
"The initial setup can be complex."
"The interface needs improvement."
