Hi,
We have database with 20GB records in total.There are 6 tables.Data increases linearly approximately, 200 MB/month. In future data needs to be archived.That means current database will store only 1 month transaction and older transactions should be moved to database on another server.Current database we are using is MS SQL 2005.
1)What database should be used for data archival?(mySQL/postGRE)
2)which web technology(ajax/jsp/python/..) will be suitable so that user can visit the website and search for archived reords?

Regards

Arjun,
1) Any database can support large amounts of data. It's disk space (and indexes) that are more important.
2) AJAX is not a server side language. It needs to be used with another language like Java or PHP. If you use Java, note that you should be using servlets and jsp, not just JSP.

Thanks.Disc space is huge,200GB.About database,I can install SQL 2005/mySQL/postGRE etc which is recommnded for archival kind of thing?It means it should not cause too much overhead.
AJAX and servlets? that means I need Tomcat or other servlet engine also right?I can go for that.which combination PHP/AJAX or servle/AJAX in terms of efficiency?Recently I used PHP and found that code is difficult to maintain.

What kind of overhead are you talking about? All DBs need to be administered.

AJAX and servlets? that means I need Tomcat or other servlet engine also right?I can go for that.which combination PHP/AJAX or servle/AJAX in terms of efficiency?Recently I used PHP and found that code is difficult to maintain.

It's hard to advise on what language to use without knowing more about the team that'd be doing the development, the existing infrastructure etc. If you don't want to use PHP, and there are no other considerations, then don't use it.
Both PHP and servlets/JSP can access databases - the web layer implementation language (and whether or not AJAX is used) really has nothing to do with how you might archive and access database data.
