Web Forms :: How To Implement Audit Trail In Project
Oct 11, 2010
I want to implement audit trail in my project. This implies keeping track of changes made in DB and later generating a report for specific data.
I'm looking for solutions other than triggers as in to have a generic solution for DB Audit trail in my project.
We'll probably be using Entity Framework 4.0. I want to explore the audit trail capabilities for the same any pointers in this directions would be helpful. also any ideas for DB Audit trail if we use Enterprise Library Data Application Block. Note:SQL Server 2008 has auditing features, but we'll not be using the Enterprise version.

We are developing a web application using asp.net and sql server. We are required to do an Audit trail for the application. As I understand this, an audit trail would basically be for all the Inserts, Updates and Deletes on the data base right? Now the way to approach this is that I have an Audit Trail Table in the DB that populates after every insert,update or delete is fired (Manually writing the script within the DAL). However any DB changes directly fired from SQL Management studio will NOT be recorded (for obvious reasons :P).
To cater for that I could create a trigger and that takes care of everything. I also did some googling and found out that SQL server has the ability to do audit trail. However the problem with using triggers is that I will NOT get the user information that logged in the website. I will get the sql user but I dont give two hoots about that, I am concerned about the website user. A solution that I figured out was either
a) Have an audit trail from my web application and also have trigger set up. On the audit report, I simply show an audit log from web application and and audit log from sql server.Obvious problems with this approach: over head. Writing to two different sets of tables on EVERY DB CHANGE.
b) I have a column called UserId ON EVERY DB TABLE. Then I create a trigger to capture all the DB changes. I pass this userId on every table I change (insert,update,delete) and the get this id from the trigger.
Obvious setbacks: unneccesary userid column in every table I do appologize for the long post. Basically I need an audit log that does log all the db changes (including direct hack to db) but at the same times gives me user login information for those db changes that were made FROM the web application.

I have a question regarding the record audit trail with EF. Recently we have started working on a application that has to have an record audit trail.Just few tables have Guid as PK, the rest of them have Int32 standard Identity setup.
The quick solution we have found is to wire up an event handler on SavingChanges and get all Added, Deleted and Modified records. But the problem is that the Inserted records for the tables that have Int32 as PK are audited with PK value of 0.
the code for the event handler looks like this:

I am in the process of creating an audit trail system. Simple enough. Certain fields require audit trail. What is the best design concept to allow this to work in multiple applications without having to change much? I would of course leave it to the admin of the site to add what fields should be audited, but the logic is the problem. Would implementing the interface IComparable be a place to start? My initial thinking is to compare 2 arrays against eachother and do an insert of what fields are in question. Array1 are the fields in the form, array2 are the fields from the sql table that require auditing.

My ASP.NET intranet web application uses Windows Authentication, and I would like to record the following details:
1) Windows ID
2) Session Start Time
3) Session Stop Time
4) URL being browsed to (optional)
I've got some basic code setup in "Session_Start" method of the Global.ASAX to log session start times (seen below), but that's it so far. I have the feeling this is a primitive approach and there are "better" ways of doing this. So I really have two questions:
1) Is this the right way to go about doing this? If not what are some other options?
2) If this is the right way, do I just need to drop some code in the "Session_End" method to record the time they exit, and thats a complete solution? Does this method always get called when they close the browser tab they have the site open in, or do they have to close the entire browser (I don't have logout functionality)? Any way users can skip over this session end method (or start for that case)?

Finally

We have an (asp.net) application that connects to a SQL Server 2008 R2 database using login credentials specifically setup for this application.
Our application access/modifies/deletes records via stored procedures, to which we pass the username of the user performing the action as a parameter.
We need to be able to keep an audit log of all updates and deletes on certain tables. The solution also needs to be as minimal as possible and not require any developer intervention.
The easiest way I can find, is to put a trigger on the table (A) that copies the 'old' data into a history table (A_History) The problem is that we need to be able to tell who performed the action, for an update this is easy we just look at username of the newly inserted record. But for a delete we do not have access to the username parameter sent to the stored procedure.
Is there any way to implement this without using things like CONTEXT_INFO(), because this would need to be added to every stored procedure and every call, which is bound to be forgotten.

I've been working on this for a while now and nothing has been a bigger pain in asp.net. I'm trying to implement custom profile fields in my visual studio 2008 web application project. I've read a lot of tutorials but they all seem to be either out dated or don't apply to web application projects. Last night I got a little closer to solving the problem when I found the "Web Profile Builder" for web applications. I've successfully set this up and can handle static profile data.I've got my web.config file setup and I can access my custom profile fields by Profile.CustomField. Now I want to figure out how I integrate this with the database and data connection. I know there are two standard ways to handle this, I would like to create new columns in the aspnet_Profile database (rather than the delimited key/value option).I'm pretty new to asp.net and this is my first project with c#, .net, and asp.

I'm currently using an SqlDataSource in ASP.NET/C# to let users insert, delete and update entries in a table/gridview. Every event needs to be written to an audit table.
I have easily implemented inserting and deleting - when inserting, the main info audited is just the parameter values of the insert query (e.Command.Parameters[0].Value.ToString() etc), and deleting is pretty much the same (just getting the ID in the delete query).
But with updating, I need to log which fields were changed and also their old values. How would I do this? As an example, here is the code for the inserting:

Suppose you have the following... An ASP.NET web application that calls a stored procedure to delete a record. The table has a trigger on it that will insert an audit entry each time a record is deleted. I want to be able to record in the audit entry the username of who deleted the record. What would be the best way to go about achieving this? I know I could remove the trigger and have the delete stored procedure insert the audit entry prior to deleting but are there any other recommeded alternative?
If a username was passed as a parameter to the delete stored procedure, is there anyway to get this value in the trigger that's excuted when the record is deleted? I'm just throwing this out there...

I am using SQL server triggers to do the database auditing for my website. My problem is that I cannot pass the username who manipulate data into the Audit table. The username saved into Audit table is always the SQL server user name which is part of my connection string. Is there any better way to handle this?

I'm trying create unit testing for an existing website project (not web application project). I cannot access my under test classes unless I use accessor. However, if I use accessor, I have problem to initiate an object with passing arguments. I only want to create unit tetsing for App_Code. After searching web, and I found that I'd better to create a web application project using my current existing website project. From solution explorer, add new project ->using existing website. My questions is: what impact will have for my current website to create the new project? Should I just convert my current website to web application? If do that, will it cuase problems on my website? I am new on asp.net, still learning..
