It's easier to move from Java or data warehousing into testing later, but harder to move from testing to one of those. (not impossible, but harder.) Given that, I think it would be good to gain experience in one of the others as your first job.

What do they consider data warehousing to be? Does it including coding or pure database admin or tooling?

Hi,
I don't know about that. If you consider data warehousing and java which one has wider aspect and i think data warehousing means its all about business analysis. I don't know anything about data warehousing.
Thank you so much for your reply.

It's also about data analysis, data architecture, data management and data-centric development. You need to understand how to design systems and applications to handle large volumes of data to serve particular business needs (e.g. BI, analytics etc) using a range of database technologies and data modelling approaches. Some people these days are also using Hadoop as a data warehouse, which introduces a completely different set of challenges.

Data warehousing (DW) can be very broad as Chris mentioned. You should find out more about what your role is in each before deciding.

In fact I did couple years of DW and the company I was with didn't really live up to my expectation of "being in the DW field".

DW in a nutshell really is working with data (architecture, analysis, design, etc). Therefore, database skills is the foundation. DW also goes hand in hand with business intelligence (BI), which can be considered to be the front end of DW (aka reporting, forecasting, etc).

One key thing about DW or BI is the tool, eg IBM Cognos, SAS, Oracle BI, SAP Business Object etc. Being in BI/DW is really learning the tool.
