Hi all,

I am having an interview on Monday. They are looking for a Java developer with strong database knowledge. They are having a huge data migration project. I have never done any data migration. What type of questions I may be asked? Can anybody tell some example of data migration using java and oracle. So that I can be prepared for this interview with some examples. I did some google search but it all about pure data migration using some data migration tools. It didn't helped that much.

Thanks in advance,
Sudha.

Well, I would assume "strong database knowledge" to mean knowledge of the SQL language.

Thank you for your reply Henry. Can you tell me how to migrate data from one server to another from a developer point of view.

Regards,
Sudha.

Data migration depends on where the source is, where the target will be, what the original format is, what the target format will be, etc.... There is no magic migrate command that will work for everything. You need to fluent in Java, SQL, and the tools that will be used.

XML and related technologies like XSLT, XPath, XQuery etc are also very useful for data migration. You can export the data from application A as A.XML and then use XSLT & XPath to translate that to B.xml understodd by application B.

Some applications provide facilities to export in an archive format e.g. A.jar or A.zip and then import into the other application.

It is bit hard to say without having more details.
 
Don't get me started about those stupid light bulbs.
