13 Database handling, project backup

13.1 General

Managing data correctly is essential to any professional company nowadays. Also for
KNX projects, possibilities exist to save them in such a way, that they are largely
protected against data loss or damage, particularly while editing the project.

13.2 Using one database per project

When you start working with ETS, one normally starts by importing all possible product
databases of the different KNX manufacturers. This however produces very large
databases. The result is that the reaction speed of these databases decreases as the
number of products increases. Moreover, it is not advisable to use a single ETS4
database, as all data would be lost in the case of a database crash.
