CHANGE

If it didn’t change, it would be called
HARDWARE
Software is easy to change
Deploying software changes
• Overwrite the old with
the new
• Side-by-side installation
• Replace the whole VM
• None of these
techniques will work for
our database code.
• The database has
“memory” or “state”
• The “state” is in the
data
• Any changes we make
need to preserve the
data, and hence the
“state”
Database Changes
How can we
make database
changes without
destroying our
data?

SCHEMA MOVEMENT SCRIPTS
SCHEMA MOVEMENT SCRIPTS
• Need to be IDEMPOTENT
– A function f : D -> D is idempotent if f (f x) = f x for
all x in D.
– i.e. repeated applications have the same effect as
one

SCHEMA MOVEMENT SCRIPTS
• Can grow to be very long
• Some changes can be complicated to
implement
• Can lead to run-time (i.e deploy-time) errors
• Emphasise the non-functional over the
functional
• Force us to use a declarative language in an
imperative manner
Declarative vs Imperative

CONNECTED DEVELOPMENT
Using the SQL Server Object Explorer in Visual
Studio, developers can now create, edit and
browse database objects located in either an onpremise database server, such as SQL Server
2008 or Microsoft SQL Server 2012, or offpremise in SQL Azure.

Project based Development
“For developers with limited or no access to a
live (production) database, SSDT provides an
improved development experience over the
existing Visual Studio database projects.”

Data Tier Applications
• Introduced in SQL Server 2008 R2
• Support added to SQL Server 2008 SP2 (but not in
SSMS!)
• Special Visual Studio project type
• Original Version only supported side-by-side
upgrades…
• In place upgrade supported in SQL Server 2008
R2 SP1 and VS2010 SP1
• .dacpac file extension
• This is the build output from SSDT
Data Tier Applications
• Deploy from Visual Studio ???
• Deploy from SSMS using the Wizard
• Deploy from the command line using
sqlpackage.exe
All of these use the DacFX API
SQLPackage.exe
• Extract: Creates a database snapshot (.dacpac)
file from a live SQL Server or Windows Azure SQL
Database.
• Publish: Incrementally updates a database
schema to match the schema of a source .dacpac
file. If the database does not exist on the server,
the publish operation will create it. Otherwise, an
existing database will be updated.
• Script: Creates a Transact-SQL incremental
update script that updates the schema of a target
to match the schema of a source.
SQLPackage.exe
• Provides greater flexibility than the SSMS
Wizard
• Can be automated using PowerShell, .bat files,
Continuous Integration tools, etc.
