If my one of customer saying they could a generate a report withing 30 second before and now they have to wait for 3min so how I can track that as a Senior Technical Support Analyst that whether it is a database issue or programming issue ?
I'm working on a system where data integrity is important so rather than just updating records we're always going to insert a new one, quite often there will be links in the system to previous versions so it'd be useful if this data was easily available.
Previously this system was being developed by a guy who's now left the company, he's been using GUIDs as Ids and that's something I'm tryin get get away from.
The current structure we have is:
RootId is the base ID and Id is the primary key, there is also an Audit table where adding an entry for the ID can mark it as deleted, this makes the select statements a bit over complicated since you have to find the maximum version for each RootId then join back to get the actual data and then join again to find any audit entries.
I was wondering, what other simpler versioning strategies are there?
id - unique id on this table
operation - insert,delete or update
table_name - name of table operation pertains to
col_name - name of the column operation pertains to
key_col - name of the key column operation pertains to
key_val - value of the key column operation pertains to
col_val_prior - value of col_name column before operation
col_val_new - value of col_name column after operation
username - name of user running operation
transaction_dt - datetime trigger was run
batch - guid that uniquely identifies an operation
I then created three triggers that I add to all tables to be audited(the triggers cover insert, update and delete operations).
This allows me to see all operations on tables I wish to audit.

Get the records from your database, using a SELECT clause.
Save that response into a variable of type array (or a generic list).
Which language are you actually using? C#, Java, C++, PHP? It depends on which framework and language you're using. The language would allow you to perform such actions on the objects (or the list of the object) that is being returned.
Usually results from the database are in a form of an array or list.

I have an rdl file as part of my solution, when I try to open it or edit it, it is opening in xml format, is there any way that I can open and edit this file, as I was working on Crystal Reports I was just able to open and make the header name changes, query changes and etc there itself and save the report that was reflecting there.
Is there anything similar here in SSRS because I want to edit the report and the xml format isn't much useful, any help like a code snippet, a link or suggestion would be greatly helpful.
