Hi Friend.......
I have two questions for you................
I am doing indexing using Lucene. I am taking data from database
But for updation in index there is problem. How can I come to know that
a row or a single data cell is get changed from row ? How can I index
only that data cell ?
1] How to track database changes in web application from front end
processing at runtime ?
2] Can get information that database is changed...... Some events from
that I will come to know that database is changed
Explanation :
I am doing indexing and searching on database. If
database gets change then I have to update index also. But how I come to
know in web application that which database record gets change and on
which table record is deleted OR inserted. So I will update that
document only from the index by uniquely identifying it.
Can get information that database is changed...... Some events
from that I will come to know that database is changed............
Can I use AJAX OR Database Triggers OR Periodical updates OR
something different for that ?
I hope I will get solution from experts like you.
Thanks.
