Database diagram connectors (SSMS 2012) - sql-server

When creating a SSMS database diagram, I can click and drag to link two columns together. I can also move the connectors along the edges of the diagram.
The problem is that SSMS places the connectors table-to-table instead of column-to-column. This makes it hard to indicate at-a-glance exactly which columns are being linked, and if I place the connectors manually, they all get rearranged if I move the table. Is there any way to "snap" the connector to a column, or even any location on the table diagram?

I do not believe the database diagram connectors in SSMS work this way, but you can request/suggest new features here: https://connect.microsoft.com/SQLServer/Feedback

options for comparing datamodels between 2 databases?

I need to identify the datamodel differences between 2 databases: DB1 and DB2. I need a way to identify missing/extra database objects and naming differences. Is there a sproc or free tool that you can recommend for this purpose?
To compare between two database schema, you can use visual studio 2015. Please follow the following steps.
Open the visual studio 2015 IDE.
Go to the tools menu according to the following image.
Then select source and destination database as per following image.
Then compare button and see the changes between source and destination database according to the following image.
After clicking update button, your destination database schema will be changed as per source database.
Thanks.

What can I do with a SQL Server diagram

I created a SQL Server diagram in SSMS. This feature looks really great, but what can I do with it? :)
It's nice to have some kind of documentation, and it's nice that you can change a field within the diagram and this will have an effect on the actual table. But what are other reasons to create a diagram?
Is it possible for example to import a full diagram in any reporting tool? I noticed that the diagram is stored in a table which has a binary column in it with a long string. Can I copy/paste this in any other diagram tools?
Thanks in advance
I have never succeeded in importing into other tools. I tried pasting it into Visio (2007) but I could not edit the object in Visio, Notice you can control how the pages are printed (Right click on the surface area and select show page breaks - you can drag the page breaks) so that each printed page contains one or more complete tables. You can use the diagram to creating indexes and foreign key relationships. I have printed out the main tables and taped it to my desk while working on a project.

sql management studio 2012 diagram

I am creating a database diagram in SQL management studio 2012. In the picture for example these tables are linked by Subscriber_id, but if you move the table diagram the line is also moved. So you don't know see the joining key.
How can I make the line statically connected to both keys no matter where you move the table diagram. Please see example.
The link represents the join between the tables, not the fields. If you inspect the link you should see the actual join details.
If you right click on one of the tables you can select to view the relationships. You can also show the relationship names which indicates the nature of the relationship.
I'm not aware of anything in SSMS to print the detail you require, but if you have access to VS and Entity Framework you can generate an entity diagram that shows the navigation properties. This can be printed.

How to get database dependency/relationship among tables

Can anyone give me an idea about database flow diagram in my SqlServer Server Management Studio? I have a database (ERBIA) in my server; I want to know about the database relationship among different tables.
You can simply click on this:
And then select the tables for which you wish to create diagrams (graphs)
By database flow diagram I think you mean an Entity Relationship Diagram (ERD). There are a number of 3rd party tools that exist to create ERDs. ERWin, Visio, ER/Studio are some examples.
These tools can read the database schema information and create a diagram and draw relationship lines based on the Foreign Key constraints. You can edit the diagrams and depending on the tool update the database or generate a DDL script for the database changes.
SQL Server also includes a database designer, but it should be noted there is no separation from a logical model and the physical model. This means if you draw a line from one table to another indicating a relationship a FK will actually be created when you save the diagram. For some scenarios this would be a problem.

Linking tables between databases

I’m after a bit of advice on the best way to go about this is SQL server 2008R2 express. I have a number of applications that are in separate databases on the same server. They are all “plugins” that use a central staff/structure list that will be in a separate database. The application is in the process of being migrated from JET.
What I’m looking for is the best way of all the “plugin” databases being able to see the central database and use those tables in standard queries and views etc.
As I’m using express that rules out any replication solution and so far the only option I can think of is to use triggers or a stored procedure to “push” out all the changes to the plugins. The information needs to be populated on a near enough real time basis however the number of changes will be very small maybe up to 100 a day and the biggest table only has about 1000 rows at the moment (the staff names table).
Hopefully that will cover all everything but if anyone needs any more details then just ask
Thanks
Apologies if I've misunderstood, but from your description it sounds like all these databases are hosted on the same instance of SQL Server - it's your mention of replication that makes me uncertain.
Assuming that's the case, you should be able to replace any copies of tables from the central database which are held in the "plugin" databases with views or synonyms which reference the central tables directly, since SQL server allows you to make references between databases on the same server using three-part naming (database_name.schema_name.object_name)
For example, if each plugin db has a table StaffNames, you could replace this with a view by dropping the table, then creating a view:
drop table StaffNames
go
create view StaffNames
as
select * from <centraldbname>.<schema - probably dbo>.StaffNames
go
and your code should continue to work seamlessly, as long as permissions are set up.
Alternatively, you could replace all the references to the shared tables in the plugin databases with three-part name references to the central database, but the view method requires less work.
