SQL Server :: Database Diagram Becomes Big - Doesn't Fit In Monitor's View
Sep 7, 2010
We have been assigned a project for future developement. The problem is original developer did not create any data model, so we are in trouble understanding how db structure flow goes. I know we can create database diagram (even did that), but db contains 162 tables so the db diagram becomes so big that it does not fit in the monitor's view. Viewing each table > keys (for relationships) is not possible.

when make buakup to my data base and open the database digram this error appear : Database diagram support objects cannot be installed because this database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects.

On a home PC I have SQL Server 2005 installed. If I go to SQL server management studio and select my database, I can then right click on the "Database Diagrams" folder and then select "New Database Diagram" from the popup menu. I can then generate a database diagram. However on my PC at work if I follow the same steps as above, the popup menu does not show an option for "New Database Diagram". Instead my choices are "Working with SQL Server 2000 diagrams" and "Refresh". So why is the "New Database Diagram" menu option missing? Also what is odd is that the popup selection reads "Working with SQL Server 2000 diagrams" when in fact I am using SQL Server 2005 not 2000? Does anyone know why my option to create a database diagram is missing?

How do you import database diagram at SQL Server Management Studio Express (SSMSE)? Using SSMSE in checking my database through a shared server, the "Database Diagrams" folder has no import functionality.

I have a producer-consumer scenario in ASP.NET. I designed a Producer class, a Consumer class and a class for holding the shared objects and responsible for communication between Producer and Consumer, lets call it Mediator. Because I fork the execution path at start-up (in parent object) and one thread would call Producer.Start() and another thread calls Consumer.Start(), I need to pass a reference of Mediator to both Producer and Consumer (via Constructor). Mediator is a smart class which will optimize many things like length of it's inner queue but for now consider it as a circular blocking queue. Producer would enqueues new objects to Mediator until the queue gets full and then Producer would block. Consumer dequeues objects from Mediator until there's nothing in the queue. For signaling between threads, I implemented two methods in Mediator class: Wait() and Pulse(). The code is something like this:
Class Mediator
{
private object _locker = new object();[code]....
Inside Mediator I use this.Pulse() every time something is Enqueued or Dequeued so waiting threads would be signaled and continue their work.But I encounter deadlocks and because I have never used this kind of design for signaling threads, I'm not sure if something is wrong with the design or I'm doing something wrong elsewhere ?

I know that I can convert a sequence diagram into a collaboration diagram easily using Rational Rose, but... Using Visual Studio, that is possible? Or I will have to create by myself?

isnt there performance analysis tools that i can use to monitor and trouble shoot things like timeout expired (slow query execution)?
I mean is there a way for me to monitor the query performance as it is run from the webpage. It runs perfectly in the SMS but it's slow when it's running from the webpages so it throws Timeout expired exception.

Custom Validation Control:
<asp:CustomValidator
ID="valSex" runat="server" ErrorMessage="1.2 <b>Sex</b> not specified"[code]...
When the page is submitted and Sex is not specified, focus is set but the 2 radio buttons are not quite in view, vertical scrolling is required to bring them into view. Shouldn't the Focus() method have brought the focus control into view?

Opening an existing asp.net 3.5 project using VWD Express 2010, the database diagram file under Database Diagrams folder went missing in Database Explorer tab. Everything is in there when I first created the diagram using VWD Express 2008. However, when I look at the .dbml file, the associated relationship between dozens of tables exist and my project runs successfully. I'm planning to create another table with relationships from existing tables but seems like I have to painfully recreate them back from scratch. How can I recover those diagrams?

With the debug mode, i know, that the app is executed. But sometimes the pages writes at every refresh the line in the database, but in most cases there is no entry in the database.

I have a table setup in the database for users who are basically going to create a classified listing. How can I setup a diagram that would easily create a table relationship with the Users table, so that it automatically inserts the users username when they submit a new ad? If so, how? I've tried adding a UserName row to my table and creating a relationship with the Users table "UserName" row, but it wasn't accepting the relationship when I tried to save the diagram...apparently because the UserName row in the Users table isn't a primary key?
Also, one this is setup, what's the best way to provide the user a way to see a list of their ads and have the ability to edit them?

I have a small app that is used to register users to the system. I am interested in having a log that will tell me, who - userid that logs in, what they do, how long. meaning, the rows they look at or update. I suppose to make a small table for this logging. lets assume a small table with only 2 columns, timestamp and the userid. It would be good to get some kind of ip address for identity.
the other parts will begood to know and interesting to learn how to code but less critical.
the signon.aspx you can see here. Is this where to code

I'm using SqlDependency to control my cache. I want to use it to monitor several tables (around 10). There should be one SqlDependency per watched table.
Should I create for each of them code like that:
public void CreateDependency_Table()
{
if (connectionStringSettings != null) [code]....
or can I reuse something between them? Like connection?Is this the preferred way of setting multiple notifications?
