Database Deployment- Synchronizing Database Structures

							?
Developing and deploying a new database is never easy. Manually synchronizing new
revisions of database structures with an already running system can become a
nightmare. If your assignment includes modifications to the structure of an existing
database, your options of performing the task without disrupting the workflow are
limited. Read this article and learn about the tools you'll need to synchronize database
structures much easier than ever before.




The Obvious Way




The simplest and most obvious way of synchronizing two databases would be by
deleting the old database and creating new structures on top of it. If you back up the
data before deleting the old database, and restore it from the backup after you're
finished updating the structures, you might just get away with it. However, this
approach is unacceptable in many environments as it disrupts the workflow and does
not provide reasonable security.




The Cheap Way




Coding a set of SQL statements and running the script on the client side is a better
idea, but still has many weaknesses as it consumes a developer's time on routine
operations, and opens the possibility for errors. If you are upgrading a database to a
new version, you'd have to apply all intermediate patches, introducing a lot more
possibilities for something to go wrong.




The Easy Way




Thinking logically, one can purchase a specialized synchronization tool, install it on
the developer side as well as distribute it among the customers. This does allow a
certain time-saving, but the method is costly and often requires paying for client-side
licenses.
The Right Way




If you don't want to code all of the updates manually, and don't want to distribute
third-party software to perform updates with your application, consider implementing
the necessary update functionality into your own application. The built-in
functionality will handle structural updates and database upgrades directly from
within your application.




Database Restyle - Library by Perpetuum Software LLC () automates the complex
process of database synchronization as much as possible without the drawbacks
associated with most third-party solutions. Database Restyle builds directly into your
application, eliminating the need to run external applications or distribute separate
solutions to your customers.




Database Restyle performs the most complex updates of database structures, allowing
both fully-automated and manually-controlled operation. Database Restyle can be
used in a wide variety of cases. It can sync the two databases, but it is not limited to
just that. Database Restyle works with other entities beside databases, such as
business objects, and supports the Linq To Sql model.




An intuitive visual environment allows Database Restyle to take snapshots of
database structures, as well as analyze, compare and synchronize databases. Running
Database Restyle as a wizard allows database developers and administrators to solve
typical tasks without coding by simply clicking the mouse. Full command line support
allows you to take snapshots and update databases from the command line.




Database Restyle - Library builds directly into your application, releasing you from
any obligations and concerns about the code. Using Database Restyle does not require
any additional licensing fees, allowing you to save on client licenses.
Handle database synchronization and updates in the right way. The free evaluation
