Analysts Much Happier with

At least one analyst found the Ascential technology "pretty impressive." Tony Baer, an analyst with onStrategies, said that up until this point, EII (enterprise information integration) competitor Informatica Corp. would always beat IBM over the head with the fact that it grew its tools organically. Informaticas tools came from the same engine and all shared the same metadata, which was "mostly but not all true," Baer said. "With Hawk, [IBM/Ascential] is saying, Weve done it," Baer said. "And they have a cool front end as well." More to the point, analysts are much happier now with IBMs metadata story, which was murky for some time. "Now the metadata engine is part of the product, instead of a separate engine that needs to be synchronized to and linked to," Baer said. "The core metadata engine is in each product, which includes classic ETL [extraction, transformation and loading], also data quality and data profiling, all off the same metadata engine. You dont have to sync to it." Click here for more on what made analysts so unhappy about IBMs formerly missing metadata story. The point is, Baer said, when youre working in a toolsay, youre developing a data extraction routineyou dont want to reinvent the wheel every time. If youre looking at source Y, you want to know what target it deals with, what parameters you run it under, and what documentation you might want to put in about when and why you run it, for example. Before IBMs integration, Ascential had a bunch of separate tools, for data movement, data staging, etc. Youd click the update button to get the latest information from DataStage, then it would deliver results, so youd have to push a button and get that stuff somewhere else.

By integrating and automating the tools, you finally dont have to worry about the people who are responsible for updating it. Check out eWEEK.coms for the latest database news, reviews and analysis.
