Dear Sir or Madam,

Yesterday, it was granted for the second time, the Database Award of the
German computer magazine "COMPUTERWOCHE" and its partner Oracle.
Innovative spirit, strategic importance to the company and sophisticated
technologies are the criteria to determine the winners. This year, DENIC
is one of them. Participating for the first time, the registry immediately
won the second place.

As the second-largest Internet registry in the world, DENIC administers
the more than 15 million domain names of the German Top Level Domain .de.
Accordingly, the requirements to be met by the database, the core
applications, like the registration system and the whois lookup service,
and the accounting system are very demanding. The data amount having grown
to terabyte level, time had come to upgrade the old database and adapt it
to today's business needs. DENIC decided to carry out a complete redesign
of the data model and launched the DB refactoring project. The aim of this
project was improved data integrity at enhanced performance to thus create
a database that facilitated future adaptations.

Database migration during ongoing operation to ensure uninterrupted
availability of all DENIC services was the particular challenge of the
project. To this end, two databases – the old one and a new one – were
operated in parallel, so that service migration could be implemented step
by step without disturbing operation. In the first step, data were entered
and continually updated in the new database. This process was accompanied
by repeated consistency checks of the old and the new database. Long-term
parallel operation of the two databases made the last step, the shut-down
of the old database on 27 December 2011, almost a formality.

All in all a tremendous challenge. The jury was impressed: "The project
illustrated how sustainability can be achieved through an innovative data
model," reads the motivation of the jury’s choice. "Moreover, the new
system was launched with a terabyte migration during ongoing operation,
and the users did not even notice it."

The result is a high-performance database that processes business
transactions up to ten times quicker than before and that provides a
future-proof data model. "Our staff has been greatly committed to
implement this project successfully," says Marcos Sanz Grossón, Head of
DENIC's Software Engineering Department. "I am very pleased about the
recognition the project has received with the Database Award; it will be
an incentive for our future work."
In a video portrait created by COMPUTERWOCHE and commented by the jury,
experts from DENIC provide background information and explicate the
meaning of the project:
Kind regards
