DDL = Data definition Language (http://en.wikipedia.org/wiki/Data_Definition_Language)

create, drop, alter,


DML = Data manipulation language (http://en.wikipedia.org/wiki/Data_Manipulation_Language)

select, insert, update, delete.

Now we start also talk about DCL = Data control language (http://en.wikipedia.org/wiki/Data_Control_Language)

so, "source" DDL probably means the scripts needed to reproduce the database entirely (only the schema)?

that refer to all the object in script to CREATE each object.  normally you put these script in VSS or SVN to kept control on the objects history.

You can not really version your Database.mdf but you can do it with the DDL script in txt format.

Example:
- one folder by object type
- one txt file by object that include DDL statement to create the object


When I want to change a DATABASE object I change the txt file in my SVN server and after used RedGate SQL compare to synh the change made in the txt file to the real object in the database.

SQL compare will convert my create proc in alter proc if the proc already exists and will kept.

After the changes are successfully deployed on live server I can commit my change in SVN whit comment on the changes (now I can see the proc history in SVN)

OK. you can always version nicely like that on the schema, but never on the data, right?

CboudrozCommented:
yes you can, redgate SQL DATA compare can do it for you.


you need to save text file like :

insert into test (test1, test2,test3) value '1', '2', '3'
insert into test (test1, test2,test3) value '1', '2', '3'
insert into test (test1, test2,test3) value '1', '2', '3'
insert into test (test1, test2,test3) value '1', '2', '3'
insert into test (test1, test2,test3) value '1', '2', '3'
